近年来,甲基锡化合物替代铅盐类稳定剂在塑料行业中得到了广泛的应用。由于工艺控制技术难度较高,甲基锡稳定剂在合成过程中,往往含有多种杂质。三甲基氯化锡是甲基锡稳定剂的主要杂质之一,也是引起职业中毒的主要原因。其毒性高,常温下可挥发,主要通过呼吸道、消化道进入体内, In recent years, methyl tin compounds instead of lead salt stabilizer in the plastics industry has been widely used. Due to the difficulty of process control technology, methyl tin stabilizer often contains a variety of impurities in the synthesis process. Trimethyltin chloride is one of the major impurities of methyltin stabilizer, which is also the main cause of occupational poisoning. Its high toxicity, volatile at room temperature, mainly through the respiratory tract, digestive tract into the body,
