| Treatment | Following oral exposure to acetone, consider insertion of a nasogastric tube to aspirate stomach contents only after recent, large acetone ingestionssymptomatic and supportive treatment is generally all that is required. Following inhalation exposure, move patient to fresh air. Monitor for respiratory distress. If cough or difficulty breathing develops, evaluate for respiratory tract irritation, bronchitis, or pneumonitis. Administer oxygen and assist ventilation as required. Treat bronchospasm with inhaled beta2 agonist and oral or parenteral corticosteroids. Irrigate exposed eyes with copious amounts of room temperature water for at least 15 minutes in case of eye exposure to acetone. In case of dermal exposure, remove contaminated clothing and wash exposed area thoroughly with soap and water. A physician may need to examine the area if irritation or pain persists. (T36) |
| 相互作用 | ... The aim of the present study was the evaluation of possible protective effects of vit E treatment against acetone-induced oxidative stress in rat RBCs. Thirty healthy male Wistar albino rats, weighing 200-230 g and averaging 12 weeks old were randomly allotted into one of three experimental groups: Control (A), acetone-treated (B) and acetone + vit E-treated groups (C), each containing ten animals. Group A received only drinking water. Acetone, 5% (v/v), was given with drinking water to B and C groups. In addition, C group received vit E dose of 200 mg/kg/day im. The experiment continued for 10 days. At the end of the 10th day, the blood samples were obtained for biochemical and morphological investigation. Acetone treatment resulted in RBC membrane destruction and hemolysis, increased thiobarbituric acid reactive substance (TBARS) levels in plasma and RBC, and decreased RBC vit E levels. Vit E treatment decreased elevated TBARS levels in plasma and RBC and also increased reduced RBC vit E levels, and prevented RBC membrane destruction and hemolysis .../Researchers/ prepared microsomes from lungs and livers of rats exposed to 20 ppm pyridine by inhalation for 5-6 hours/day for 10 days, to acetone (7.5%, v/v) in drinking water for 10 days or by inhalation to 50% aqueous acetone for 5-6 hours/day for 10 days, or to acetone in combination with pyridine administered separately as above. Controls received water for inhalation and oral exposures. In the liver microsomes, there was induction of ethoxyresorufin O-deethylase (EROD) activity for oral acetone by 2.5-fold, for pyridine by inhalation by 2.8-fold, and for the combination of acetone and pyridine by 7.6-fold, indicating greater-than-additive interaction. The levels of CYP1A1 were induced by acetone, pyridine, and the combination by 8.3-, 6.6-, and 32.7-fold, respectively. These results indicated even greater synergistic interaction. Similar greater-than-additive interaction results were also found for methoxyresorufin O-demethylase (MEROD) and CYP1A2 in the liver microsomes. Microsomal EROD was induced by all treatments in the lung, and a synergistic interaction was even greater in the lung, with an increase that was 4-fold for acetone, 21-fold for pyridine, and 115.5-fold for the combination. CYP1A1 was also induced synergistically by acetone and pyridine in the lung microsomes./In a previous study it was/ demonstrated that acetone potentiated the nerve conduction velocity and neurobehavioral effects of 2,5-hexanedione in rats, but /it was/ noted that the mechanism of action of this potentiation was not fully understood. More recently, /researchers/ performed similar experiments. This time, they included histological examination of the sciatic and tibial nerves in rats immediately after the 6-week exposures in rats allowed a 10-week recovery period. As in previous experiments, acetone potentiated 2,5-hexanedione-induced open field ambulation and rearing balance in the rotarod tests, and grip strength. The ambulation was reversible during the recovery period by all treatments, but the effects on rearing and balance were reversible in the 2,5-hexanedione group only. That is, the potentiation by acetone persisted. Histological examination revealed that after exposure, giant axon swelling was induced by 2,5-hexanedione and the combination of 2,5-hexanedione and acetone, and a change in the distribution of fiber area size occurred in rats exposed to 2,5-hexanedione. The lesions observed in the co-exposure group were statistically similar to the effects of 2,5-hexanedione alone, but appeared aggravated by co-exposure, as seen by conventional pathological evaluation. After the 10-week recovery period, the nerve tissues appeared normal. The investigators concluded that neurotoxicity of the combined exposure was not reversible and that the mechanism of acetone potentiation is probably an effect on the toxicokinetics of 2,5-hexanedione.Pretreatment with acetone for 6 days (one-tenth the LD50) potentiated acute ethanol toxicity in rats. ... /Investigators/ ... demonstrated that acetone pretreatment potentiates chlorinated hydrocarbon toxicity. ... Acetone protected animals against electroshock or isonicotinic acid hydrazide-induced convulsions. Acetone ... enhanced the hepatotoxicity of 1,1-dichloroethylene (200 ppm) in rats.For more Interactions (Complete) data for ACETONE (13 total), please visit the HSDB record page. |

| 環境中動態 | TERRESTRIAL FATE: Based on a classification scheme(1), an estimated Koc value of 2.4(SRC), determined from a structure estimation method(2), indicates that acetone is expected to have very high mobility in soil(SRC). Volatilization of acetone from moist soil surfaces is expected to be an important fate process(SRC) given a Henry's Law constant of 3.50X10-5 atm-cu m/mole(3). Acetone is expected to volatilize from dry soil surfaces(SRC) based upon its vapor pressure of 231 mm Hg at 25 °C(4). A 96% of theoretical BOD using activated sludge in the Japanese MITI test(5) suggests that biodegradation is an important environmental fate process in soil(SRC). Results of other screening tests also indicate that acetone is readily biodegradable under both aerobic and anaerobic conditions(6,7).AQUATIC FATE: Based on a classification scheme(1), an estimated Koc value of 2.4(SRC), determined from a structure estimation method(2), indicates that acetone is not expected to adsorb to suspended solids and sediment(SRC). Volatilization from water surfaces is expected(3) based upon a Henry's Law constant of 3.50X10-5 atm-cu m/mole(4). Using this Henry's Law constant and an estimation method(3), volatilization half-lives for a model river and model lake are 21 hours and 8.8 days, respectively(SRC). Experimentally determined volatilization half-lives in a shallow stream were measured in the range of 8-18 hours(5-7). According to a classification scheme(8), an estimated BCF of 3(SRC), from its log Kow of -0.24(9) and a regression-derived equation(2), suggests the potential for bioconcentration in aquatic organisms is low(SRC). A 96% of theoretical BOD using activated sludge in the Japanese MITI test(10) suggests that biodegradation is an important environmental fate process in soil(SRC). Results of other screening tests also indicate that acetone is readily biodegradable under both aerobic and anaerobic conditions(11,12). Volatilization may be faster removal mechanism of acetone than biodegradation in very shallow, rapidly moving water(5-7). Acetone is not expected to undergo hydrolysis in the environment due to the lack of functional groups that hydrolyze under environmental conditions(3).ATMOSPHERIC FATE: According to a model of gas/particle partitioning of semivolatile organic compounds in the atmosphere(1), acetone, which has a vapor pressure of 231 mm Hg at 25 °C(2), will exist solely as a vapor in the ambient atmosphere. Vapor-phase acetone is degraded in the atmosphere by reaction with photochemically-produced hydroxyl radicals(SRC)the half-life for this reaction in air is estimated to be about 89 days(SRC) calculated from its rate constant of 1.80X10-13 cu cm/molecule-sec at 25 °C(3). Acetone absorbs at wavelengths >290 nm(4) and, therefore, may be susceptible to direct photolysis by sunlight(SRC). Results of photolysis tests indicate that acetone has a direct photolysis half-life in the range of 10-80 days in the troposphere depending upon solar angle and sunlight intensity(5,6). Acetone has been detected in rain and cloud water(7), and therefore, may be removed from the air by wet deposition(SRC). |

| FIFRA 要件 | Residues of acetone are exempted from the requirement of a tolerance when used as a solvent, cosolvent in accordance with good agricultural practice as inert (or occasionally active) ingredients in pesticide formulations applied to growing crops or to raw agricultural commodities after harvest.Residues of acetone are exempted from the requirement of a tolerance when used in accordance with good agricultural practice as inert (or occasionally active) ingredients in pesticide formulations applied to animals. Use: solvent, cosolvent.As the federal pesticide law FIFRA directs, EPA is conducting a comprehensive review of older pesticides to consider their health and environmental effects and make decisions about their continued use. Under this pesticide reregistration program, EPA examines newer health and safety data for pesticide active ingredients initially registered before November 1, 1984, and determines whether the use of the pesticide does not pose unreasonable risk in accordance to newer safety standards, such as those described in the Food Quality Protection Act of 1996. Pesticides for which EPA had not issued Registration Standards prior to the effective date of FIFRA '88 were divided into three lists based upon their potential for human exposure and other factors, with List B containing pesticides of greater concern than those on List C, and with List C containing pesticides of greater concern than those on List D. Acetone is found on List D. Case No: 4002Case Status: No products containing the pesticide are actively registered. Therefore, we are characterizing the case as "cancelled." Under FIFRA, pesticide producers may voluntarily cancel their registered products. EPA also may cancel pesticide registrations if registrants fail to pay required fees or make/meet certain reregistration commitments, or if EPA reaches findings of unreasonable adverse effects.Active ingredient (AI): acetoneAI Status: The active ingredient is no longer contained in any registered products. Thus, we characterize it as "cancelled." |

説明
Acetone is a flammable, colorless liquid with a pleasant odor. It is used widely as an organic solvent and in the chemical industry. It is the simplest ketone, which also goes by the name dimethyl ketone (DMK). Acetone was originally referred to as pyroacetic spirit because it was obtained from the destructive distillation of acetates and acetic acid.
天然物の起源
Reported found in apple, pear, grape, pineapple, strawberry, raspberry, tomato, black currant, citrus, onion and potato; also reported found in cocoa leaves, in Mexican goosefoot and in the oils of coriander and lavender. In trace amounts it has been reportedly identified in the oil of bitter orange, in distilled wine and in coffee aroma
来歴
The traditional method of producing acetone in the 19th century and the beginning of the 20th century was to distill acetates, particularly calcium acetate, Ca(C2H3O2)2. Weizmann discovered a process to produce butyl alcohol and acetone from the bacterium Clostridium acetobutylicum in 1914. With England’s urgent demand for acetone, Winston Churchill (1874–1965) enlisted Weizmann to develop the Weizmann process for acetone production on an industrial scale. Fermentation and distillation techniques for acetone production were replaced starting in the 1950s with the cumene oxidation process . In this process, cumene is oxidized to cumene hydroperoxide, which is then decomposed using acid to acetone and phenol. This is the primary method used to produce phenol, and acetone is produced as a co-product in the process, with a yield of about 0.6:1 of acetone to phenol.
使用
Acetone′s luminesence intensity is dependent upon the solution components 1. The absorption of UV light by acetone, results in its photolysis and the production of radials 1.

製法・合成法
調製方法
Acetone is obtained by fermentation as a by-product of n-butyl alcohol manufacture, or by chemical synthesis from isopropyl alcohol; from cumene as a by-product in phenol manufacture; or from propane as a by-product of oxidation-cracking.
