丙烯腈是一种无色、有刺激性气味的易燃液体,略溶于水,易溶于一般有机溶剂,可作为单体制备聚合物,如聚丙烯腈、腈纶纤维和丁腈橡胶。长时间吸入能引起恶心、呕吐、头痛、疲倦等症状,是一种致癌物质。我国规定工作场所空气中丙烯腈的时间加权平均容许浓度(PC-TWA)为1 mg/m3,短时间接触容许浓度(PC-STEL)为2 mg/m3[1]。国家标准检测方法和美国国家职业安全与卫生研究院(NIOSH)的检
Acrylonitrile is a colorless, irritating odor flammable liquid that is slightly soluble in water and soluble in common organic solvents. It can be used as a monomer to make polymers such as polyacrylonitrile, acrylic fiber and nitrile rubber. Prolonged inhalation can cause nausea, vomiting, headache, tiredness and other symptoms, is a carcinogen. China stipulates that the airborne workplace airborne acrylonitrile time-weighted average allowable concentration (PC-TWA) of 1 mg / m3, short-term exposure to allowable concentration (PC-STEL) of 2 mg / m3 [1].
