丁酮(甲基乙基甲酮,2-butanone,methylethyl ketone,CH_3COCH_2CH_3),简称M.E.K.。工业上主要用于制造油漆、胶涂料、橡胶、树脂、塑料、胶卷、水泥等。丁酮是脱脂剂的通用成分。在石油加工、制鞋、制药、化妆品的生产上和各种化学实验室中应用非常广泛。为制定我国丁酮的卫生标准,本文对丁酮的毒理研究资料介绍如下。 一、理化特性 丁酮为无色透明、易挥发的液体,有丙酮样气味。分子量:72.06;比重:0.8072(25/25°);沸点:79.6℃;溶点:-87℃;蒸气比重:2.41;蒸气压力:133.3Pa(25℃);闪点:-6.1℃;爆炸极限:1.8～10%。能溶于水和有机溶剂。易
Butanone (methyl ethyl ketone, 2-butanone, methylethyl ketone, CH 3 COCH 2 CH 3), referred to as M.E.K. Industrial mainly used in the manufacture of paint, plastic coating, rubber, resin, plastic, film, cement and so on. Butanone is a common ingredient for degreasing agents. In petroleum processing, shoemaking, pharmaceuticals, cosmetics production and a variety of chemical laboratory is widely used. In order to develop the hygienic standard of butanone in our country, this paper describes the toxicological data of butanone as follows. First, the physical and chemical properties of methyl ethyl ketone colorless, transparent, volatile liquid, acetone-like odor. Molecular Weight: 72.06; Specific Gravity: 0.8072 (25/25 °); Boiling Point: 79.6 ° C; Melting Point: -87 ° C; Vapor Specific Gravity: 2.41; Vapor Pressure: 133.3Pa (25 ° C); Flash Point: -6.1 ° C; : 1.8 ~ 10%. Soluble in water and organic solvents. easy
