有机锡类化合物分为一烃基锡(R_1SnX_3)、二烃基锡(B_2SnX_2)、三烃基锡(R_3SnX_3)和四烃基锡(R_4Sn)四大类。式中R多为烷基:X多为卤素,氧或有机酸类。三烃基锡和四烃基锡主要损害中枢神经系统,毒性最大;其次为二烃基锡,主要引起肝胆系统的损伤;一烃基锡毒性最小。目前,工业中最常用的是二烷基锡类化合物。据估计,全世界1986年有机锡总产量将达63,000吨,其中70％以二烷基锡的形式作为聚氯乙烯塑料的光热稳定剂(成品中约含0.5～2.0％).另外,二烷基锡可用作聚氨基甲酸乙酯泡沫塑料催化剂、橡胶熟化剂、抗氧化剂等。
Organotins are classified into four groups, R 1 Sn X 3, B 2 Sn X 2, R 3 Snn 3 and R 4 Sn. In the formula, R is mostly alkyl: X is mostly halogen, oxygen or organic acids. Trialkyltin and tetraalkyltin mainly damage the central nervous system and have the highest toxicity; followed by dihydrocarbyltin, which mainly causes hepatobiliary damage; At present, dialkyl tin compounds are the most commonly used in the industry. It is estimated that the total organic tin production in the world will reach 63,000 tons in 1986, of which 70% will be in the form of dialkyl tin as the light and heat stabilizer of polyvinyl chloride plastic (about 0.5 to 2.0% in the finished product) .In addition, Alkyl tin can be used as polyurethane foam catalyst, rubber curing agent, antioxidant and so on.
