2-헥사논 C화학적 특성, 용도, 생산
개요
2-Hexanone has been used as a solvent for both cellulose- and resin-based coating systems. In the early 1970s, a number of workers in the print department of a coated fabrics plant developed severe peripheral neuropathy from an unknown cause. In search of an etiological agent, and in the absence of other neurotoxicants, 2-hexanone was implicated as it was recently substituted for methyl isobutyl ketone in the manufacturing process. Similar observations in workers exposed to 2-hexanone may have resulted in the decline in production and use in the United States.화학적 성질
2-Hexanone is a colorless to pale yellow liquid with a sharp odor. It dissolves very easily in water and is miscible in ethanol, methanol, and benzene. 2-Hexanone evaporates easily into the air as a vapor. It is stable, flammable, and incompatible with oxidizing agents, strong bases, and reducing agents. 2-Hexanone is a waste product of wood pulping, coal gasifi cation, and oil shale operations. Formerly, 2-hexanone was in use as a paint and paint thinner with other chemical substances, and to dissolve oils and waxes.and is used as a solvent and organic syn- thesis intermediates. However, the industrial uses of 2-hexanone is now very much restricted.물리적 성질
Clear, colorless to pale yellow, flammable liquid with an odor resembling acetone and 2-butanone. Nagata and Takeuchi (1990) reported an odor threshold concentration of 24 ppbv. Amoore and Hautala (1983) reported odor threshold concentrations of 250 μg/L and 76 ppbv in water and air, respectively.용도
2-Hexanone is used in various organic chemical syntheses. It is used in the synthesis of (+/-)-monomorine. It is also used in the preparation of alcohols by transfer hydrogenation of ketones.생산 방법
MnBK can be produced by a reaction between acetic acid and ethylene under pressure MnBK can be produced by a reaction between acetic acid and ethylene under pressure.일반 설명
A clear colorless liquid. Flash point 95°F. Less dense than water. Vapors heavier than air.공기와 물의 반응
Highly flammable. Slightly soluble in water.반응 프로필
2-Hexanone is incompatible with oxidizing agents. 2-Hexanone may also react with strong bases and reducing agents.위험도
Flammable, moderate fire risk, explosive limits 1.2–8% in air. Irritant to eyes and mucous membranes, narcotic in high concentration, absorbed by skin. Causes peripheral neuropathy and testicular damage.건강위험
Inhalation of high concentrations of vapor may result in narcosis; peripheral neuropathy may develop. Ingestion of large amounts may cause some systemic injury. Contact with eyes causes mild to moderate irritation. Liquid irritates skin; prolonged or repeated contact may cause defatting of the skin with resultant dermatitis.화재위험
2-Hexanone is flammable.잠재적 노출
The material is used as a solvent환경귀착
Biological. Using the BOD technique to measure biodegradation, the mean 5-d BOD value (mM BOD/mM 2-hexanone) and ThOD were 5.22 and 61.4%, respectively (Vaishnav et al., 1987).Photolytic. A second-order photooxidation rate constant of 8.97 x 10-12 cm3/molecule?sec for the reaction of 2-hexanone and OH radicals in the atmosphere at 299 K was reported by Atkinson (1985).
Chemical/Physical. 2-Hexanone will not hydrolyze because it has no hydrolyzable functional group (Kollig, 1995).
저장
2-Hexanone should be kept stored in a tightly closed container, in a cool, dry place, away from sources of ignition.운송 방법
UN1224 Ketones, liquid, n.o.s., Hazard Class: 3; Labels: 3-Flammable liquid, Technical Name Required폐기물 처리
Dissolve or mix the material with a combustible solvent and burn in a chemical incinerator equipped with an afterburner and scrubber. All federal, state, and local environmental regulations must be observed.주의 사항
Occupational workers should be careful when using and handling 2-hexanone. Workers should wash thoroughly after handling the chemical substance. Workers should avoid contact of 2-hexanone with the eyes, skin, and clothing and also avoid contact with heat, sparks, and flame.2-헥사논 준비 용품 및 원자재
