It is one of the least hazardous organic sol- vents. Acute exposure can cause mucous membrane irritation, headache, and narcosis. No deaths due to acute exposure'have been recorded. There is no systemic injury associated with chronic inhalation of low con- centrations of acetone. The occupational standard for an 8-hour time weighted average exposure is 1000 ppm. Acetone has shown little reac- tivity in irradiation studies and is not an important component in photo- chemical oxidant formation. Simple diffusion modeling estimates place the likely maximum 1-hour aver- age ambient concentration at about 4 ppm. The maximum 24-hour average ambient concentration might be expected to be about 2 ppm. About 2 billion pounds of acetone were produced at 12 plants in 1974, with about 30 percent being used as a solvent. Production is expected to in- crease by 6 percent per year through 1978. Emissions result primarily from solvent usage, production, use as an absorbent packing for acetylene, bulk storage, and end-product manufacturing. About one-third of total production is eventually lost as emissions. Two types of emission controls are used extensively by the industry. These are vapor recovery and incineration. Control by adsorption on activated charcoal is used when recovery is economically desirable. The primary advantage of incineration is that low concentrations may be oxi- dized with only small supplemental fuel requirements. Fixed roof storage ------- tanks can be controlled by venting to an adsorber or incinerator, or they can be converted to floating roof design. Based on the results of the health effects research presented in this report, and the ambient concentration estimates, it appears that acetone as an air pollutant does not pose a threat to the health of the general population. In addition, acetone does not appear to pose other environ- mental insults xdiich would warrant further investigation or restriction of its use at the present time. ------- SECTION II AIR POLLUTION ASSESSMENT REPORT PHYSICAL AND CHEMICAL PROPERTIES Acetone is a colorless, highly flammable liquid with a characteristic pungent, mintlike odor and taste. The main industrial methods of manu- facture are the catalytic dehydrogenation of isopropanol and the oxida- tion of cumene. Acetone is used as an intermediate in the manufacture of methyl methacrylate and other chemicals. It is also widely used in lacquers and varnishes as a solvent, and in the rubber, dyeing, celluloid, rayon acetate and leather industries. It is a solvent for many fats and oils, a stain remover, and a common labo; properties of acetone are listed in Table 1. and oils, a stain remover, and a common laboratory solvent. Significant HEALTH AND WELFARE EFFECTS Effects on Man Acute Poisoning - Acetone is one of the least hazardous organic solvents. At high concentrations it acts on the central nervous system, producing narcosis or stupor, ketone bodies in the blood, and inflammation of the gastrointestinal tract accompanied by vomiting. At lower concentrations it will produce headache and mucous membrane irritation of the eyes, nose, and throat. Some dose-reponse data are summarized in Table 2. The odor of acetone is detectable without any background interference at 100 ppm. Humans never exposed to acetone vapor complained of slight •> eye, nose, and throat irritation at 300 ppm and 500 ppm. After a short ------- Table 1.

Awareness of mucous membrane irritation did not begin until 1,000 ppm to 1,500 ppm. However, many investigators have concluded that eye irritation does not become a factor until 2,500 ppm. The degree of irritation varies with individual susceptibility, with irritation disappearing after removal from the vapors. Symptoms of intoxication are similar to those seen after ethanol ingestion. Death due to acute exposure has never been recorded, but it is possible via narcosis leading to anesthesia and respiratory failure after prolonged exposure to high concentrations. Acetone taken in doses of 15 to 20 g daily for several days produced no ill effects other than drowsiness. An occasional-short exposure would not cause skin irritation. The danger of skin absorption is very slight and would not be significant in contributing to intoxication. Acetone is readily absorbed into the blood and is distributed throughout the body, with the majority exhaled unchanged by the lungs. Chronic Poisoning There is no systemic injury associated with the chronic inhalation of low concentrations of acetone. Workers have been exposed to concentrations averaging up to 2,000 ppm for up to 15 years without any ill effects. It has been stated that the worst that can happen to men g chronically exposed to such concentrations is a temporary dull headache. The United States Occupational Standard for an 8-hour time weighted average 9 is 1,000 ppm based on studies concerning industrial exposures. However, it may not be low enough to prevent all narcotic symptoms. Effects on Animals Acute Poisoning - The effects of acute exposure to acetone vapor for some animals are summarized in Table 3. As in man, it acts as an irritant to the mucous membrane in addition to acting on the central nervous sys- tem. Symptoms of intoxication are salivation, lachrymation, twitchings and convulsions leading to narcosis and respiratory failure. Eye irritation is temporary and disappears upon removal from the vapor. Skin absorp- tion of the vapor is considered slight and does not contribute to poisoning. ------- The only organ to be specifically injured by acetone poisoning is the kidney, with some investigators reporting lesions of the convoluted o tubules, or degeneration.

Cats repeatedly exposed to 1,265 to 2,110 ppm were found to suffer no ill effects except slight irritation of the eyes and nose." resulted in an increased tolerance to the vapor. Chronic exposure Effects on Vegetation The effects of acetone vapor on vegetation have not been well documented in the literature. Considering its properties as a solvent for oils and fats, leaf contact with acetone would probably cause a breakdown of tis- sue resulting in massive injury or plant death. A Russian study noted the combined effect of 0.74 ppm (1.75 mg/m3) acetone, 2.28 ppm (2.62 mg/m ) ethylene, 0.43 ppm (1.1 mg/m3) acetic acid, and 28 ppm (18.4 mg/m ) methane on the growth of English oak, English hawthorne, and Tartarian dogwood near a chemical plant. The gases were seen to retard growth in the tree shoots where growth processes are usually most intense. Growth in the ------- crown of trees on the side near the chemical plant was retarded more than growth on the opposite side. However, growth retardation may not be due entirely to acetone, since ethylene is an extremely sensitive growth inhibitor. Effects on Materials There are no data in the literature documenting the effects of acetone as an air pollutant on materials. Recognizing its properties as a solvent, when present in sufficient concentration it could become active in dissolving some forms of plastic or rubber. , Other Effects Acetone and Photochemical Smog - It is well documented that reactions involving hydrocarbons taking place in photochemical smog produce ozone and peroxyacetyl nitrate (PAN), two chemicals extremely toxic to plants and 11 12 man. Acetone has shown little reactivity in irradiation studies. ' Its contribution to producing significant amounts of PAN or ozone in the ambient'air is negligible. AMBIENT CONCENTRATIONS AND MEASUREMENT Ambient Concentration Estimates Although acetone emissions are greatest from the solvent usage source category, these sources tend to be small and geographically scattered. Production of acetone, however, occurs at a few locations for which the emissions characteristics can be fairly well defined, and which as single point or area sources have a large emission density. The largest installation for acetone production is located in a town of about 15,000 population, and it has a capacity of about 400 million Ib/yr. Assuming a 1 percent loss, this converts to an emission rate of: ------- (0.01 emission factor) (400 x 106 Ib/yr) (453.6 g/lb) 3.1536 x 107 sec/yr = 57.5 g/sec of acetone. Some assumptions must be made regarding this acetone release to the atmosphere. First of all, the emissions do not all come from one source location, but rather from a number of locations within the plant where acetone vapor leaks to the atmosphere. Thus, the emissions can be charac- terized as coming from an area source which will be taken to be 100 meters on a side. Secondly, the emissions occur at different heights, and an average emission height of 10 meters is assumed. Ground level concentrations can then be estimated at locations downwind 13 of the facility. To do this a virtual point source of emission is assumed upwind of the facility at a distance x^here the initial horizontal dispersion coefficient equals the length of a side of the area divided by 4.3. In this case: o = 100m/4.3 = 23.3m yo Assuming neutral stability conditions (Pasquill-Gifford Stability Class D) with overcast skies and light winds, the upwind distance of the virtual point source is approximately 310 meters. With consideration of the plant boundary, it is reasonable to assume that the nearest receptor location is thus about 500 meters from the virtual point source. Finally, taking 2 m/sec as an average wind speed, the ground level concentration may be calculated from: X = uiro a y ------- or = 57.5 X (2)TT(36)(18.5) w = 1.187 x 10~2 g/m3 for a 10-minute average concentration. Over a period of an hour this becomes (1.187 x 10~2 g/m3)(0.72) = 0.855 x 10~2 g/m3 or 3.7 ppm 1-hour average concentration. Over a 24-hour period, the average concentration might roughly be expected to be about 2.0 ppm. ' Measurement Techniques There are a number of techniques for determining acetone in air, includ- ing wet chemical methods, spectrographic methods, and gas chromatographic methods. All three basic analytical techniques are capable of detecting acetone in air in the parts per hundred million range. The determination of acetone by the wet chemical methods generally in- volves titration of iodoform which is produced by the quantitative reac- tion of acetone and iodine. Acetone samples may be collected either by fritted bubblers containing water or by adsorption on silica gel. Concentrations of the order of 10 ppm may be determined by this method; however, it is not specific for acetone and other methyl ketones will interfere. Collection in water using fritted bubblers is less desirable for field use due to the extra equipment requirements. Concentrations as low as 0.04 ppm may be determined by spectrophotometry. The sample is collected in 2,4-dinitrophenylhydrazine, treated with car- bon tetrachloride and sodium hydroxide, and read in a spectrophotometer at 420 nanometers. ------- In the gas chromatographic method the sample is collected on charcoal and subsequently desorbed with carbon disulfide. The presence and concentra- tion of acetone are determined by the characteristic retention time and the area of the breakthrough curve. ' SOURCES OF ACETONE EMISSIONS Acetone Production and Consumption 18 The production of acetone in 1974 was 2,073 million pounds, and it is ex- 19 pected to increase at 6 percent per year through 1978. Approximately 30 percent of all acetone produced is used as"a solvent for protective coatings and chemical processing. Presently 12 companies using the cumene or isopropyl alcohol process are manufacturing acetone (see Appendix A). The consumption of acetone for final products is shown in Table 4. This table also presents the expected growth rates for each sector of the market. Acetone Sources and Emission Estimates Primary sources of emissions of acetone result from solvent usage, ace- tone manufacturing, absorbent packing for acetylene, bulk storage, and end product manufacturing. Total emissions from all categories are estimated to be 698 million pounds, representing 34 percent of total production. See Table 5. The major source of acetone emissions results from its use as a solvent, mainly for protective coatings. It is assumed that all acetone used as a solvent will evaporate to the atmosphere. In 1974, an estimated 85 mil- lion pounds were used in paints, varnishes and lacquers, and 125 million pounds were used in thinners and wash solvents. Consumption of acetone for Pharmaceuticals (toiletries and cosmetics) accounted for 123 million pounds. Its use as a chemical processing solvent amounted to approximately 107 million pounds. The production of cellulose acetate consumed 80 10 ------- Table 4.

The second major source of emissions, other than from solvent usage, is the manufacture of acetone. In 1974, 58 percent of total acetone capacity in the United States and Puerto Rico was based on cumene oxida- tion, the remaining 42 percent was based on isopropyl alcohol. The oxidation of cumene is used by 9 of the 12 acetone producers. In this process acetone is produced as a coproduct with phenol by cleaving the cumene hydroperoxide obtained from the air oxidation of cumene. The reactions are presented below: ' OOH cumene hydroperoxide phenol CH3CO acetone Two processes for the production of acetone from isopropyl alcohol are currently used: catalytic dehydrogenation and oxidation. The dehydro- genation process converts isopropyl alcohol to acetone by heating it to 400°C in the presence of a brass or copper catalyst. The reaction is as follows: CH3 CH CH, OH isopropyl alcohol catalyst 400°C CH3CO acetone hydrogen 12 ------- The oxidation process converts isopropyl alcohol to hydroperoxide with oxygen, which on hydrolysis produces hydrogen peroxide and acetone. The reaction is presented below: CH3 CH CH3 OH isopropyl alcohol + 02 oxygen H2°2 hydrogen peroxide + CH3CO CH3 acetone Since there are no data available concerning emissions from these pro- 20 cesses, based on other similar chemical processes it is estimated that 1 percent of production is emitted as acetone. On this basis 21 million pounds of acetone are lost during the production cycle. Using the same emission factor, losses from end product manufacturing are 12 million pounds. The next major source of acetone emission results when it is used to saturate absorbent packing in acetylene cylinders. This mitigates ex- cessive pressure so that the cylinders can be shipped safely. Emissions from this source are estimated to have been 15 million pounds in 1974. The last major source of emissions results from bulk storage of acetone. 20 Using the emission factors in AP-42 and assuming all storage tanks are fixed roof, emissions are 13 million pounds. ACETONE EMISSION CONTROL METHODS The literature does not report specific control equipment for acetone emissions, but it does report on control devices for other similar hydro- carbons. Two types of control devices are presently used by the industry to control hydrocarbon emissions: vapor recovery and incineration. Both systems have reported efficiencies of at least 95 percent. 13 ------- Control of hydrocarbon emissions by adsorption on activated charcoal is generally applied when recovery of adsorbed material is economically desirable. Adsorption is generally used when concentrations of hydro- 21 carbons are greater than 2500 ppra. Other applications are for the control of very low concentration hydrocarbons that are poisonous to catalytic incinerators, and for collection and concentration of low con- centration emissions for subsequent disposal by incineration. Cost data for the cases utilizing adsorption are presented in Tables 6 and 7. The three cases presented are adsorption with solvent recovery, adsorption with incineration, and adsorption vith incineration plus heat recovery. Table 6.

Indicates a savings. 14 ------- Control of acetone emissions by incineration or catalytic oxidation in- volves direct oxidation of the combustible portion of the effluent, the desired ultimate products being water and carbon dioxide. The primary advantage of catalytic incineration is that extremely small concentrations of organics can be oxidized x^ith only small amounts of supplemental fuel required. The main disadvantages are the higher capital cost and the fact that certain hydrocarbons may poison the catalyst. Cost data for thermal and catalytic incinerators with and 22 without heat recovery are presented in Tables 8 and 9. Control of emissions from storage tanks will require the use of floating roof tanks or venting the emissions to the previously mentioned adsorber or incinerator. Emissions from fixed roof tanks can be vented to either system without any major increase in cost. If these systems are not available, the fixed roof tanks should be switched to floating roof tanks resulting in a 90 percent reduction of emissions. Figure 1 provides 22 estimated costs of various gasoline storage tanks. These equipment cost estimates can also be applied to acetone. As can be seen, conversion of fixed roof to floating roof tanks by installation of internal floating covers is more economical than the installation of new pontoon floating tanks. 15 ------- Table 8.
