                      三氯甲苯C6H5CCl3氣體檢測(cè)管132SC Trichlorotoluene 0.2-4ppm

                      簡(jiǎn)要描述:

                      三氯甲苯C6H5CCl3氣體檢測(cè)管132SC Trichlorotoluene 0.2-4ppm,三氯甲苯又稱芐川三氯(toluenetrichloride)。結(jié)構(gòu)簡(jiǎn)式C6H5CCl3。無色有強(qiáng)烈氣味的液體。不溶于水,可溶于乙醚、乙醇和苯。用于化學(xué)工業(yè)、塑料、染料的生產(chǎn)、香料工業(yè)等。大鼠吸入4h的Z小致死濃度為125ppm,經(jīng)口致死量為6g/kg(體重)。主要經(jīng)呼吸道進(jìn)入體內(nèi),對(duì)粘膜(特別是眼結(jié)膜)有刺激作用。高濃度吸入可致化學(xué)性肺炎和肺水腫。皮膚接觸可引起紅斑、大皰和濕疹。根據(jù)報(bào)道可致小鼠癌
