三丁基氧化锡简介
Tributyltin oxide (TBTO) is an organotin compound chiefly used as a biocide (fungicide and molluscicide), especially a wood preservative. Its chemical formula is [(C4H9)3Sn]2O. It has the form of a colorless to pale yellow liquid that is only slightly soluble in water (20 ppm) but highly soluble in organic solvents. It is a potent skin irritant.
Tributyltin compounds had been used as marine anti-biofouling agents. Concerns over toxicity of these compounds have led to a worldwide ban by the International Maritime Organization. It is now considered a severe marine pollutant and a Substance of very high concern by the EU.
生产方法
由无水四氯化锡与丁基溴化镁反应生成四丁基锡,再与四氯化锡发生重分解反应生成三丁基氯化锡,最后与氢氧化钾反应得到三丁基氧化锡。
用途
1.氧化剂。分解单酯(包括含有肽键的)。杀真菌剂。杀菌剂。杀虫剂。防污漆。
2.有机锡的分子能透过细胞膜,与蛋白质及酶中的酸性基团缔合的阳离子竞争,使细胞代谢极度紊乱而导致微生物死亡。有机锡可用来抑制产生黏泥的细菌,对硫酸盐还原菌和某些产气菌的杀灭效果也较好。
3.用于制取防腐漆和农药,如熏蒸剂和杀毒剂。
