三氯甲苯C6H5CCl3气体检测管132SC Trichlorotoluene 0.2-4ppm

简要描述:

三氯甲苯C6H5CCl3气体检测管132SC Trichlorotoluene 0.2-4ppm,三氯甲苯又称苄川三氯(toluenetrichloride)。结构简式C6H5CCl3。无色有强烈气味的液体。不溶于水,可溶于乙醚、乙醇和苯。用于化学工业、塑料、染料的生产、香料工业等。大鼠吸入4h的Z小致死浓度为125ppm,经口致死量为6g/kg(体重)。主要经呼吸道进入体内,对粘膜(特别是眼结膜)有刺激作用。高浓度吸入可致化学性肺炎和肺水肿。皮肤接触可引起红斑、大疱和湿疹。根据报道可致小鼠癌
