二丁基氧化锡的制备改进

Prepartion on Dibrtyltin Oxide

用甲苯和少量四氢呋喃作溶剂 ,通过格氏反应由四氯化锡制备了四丁基锡 ,四丁基锡与四氯化锡直接反应冷却后得二丁基二氯化锡粗品 ,随后用二丁基二氯化锡粗品的乙醚溶液直接水解制备二丁基氧化锡高并反应收率均大于 90 %。

Dibutyltin oxide was prepared by reaction of tin (Ⅳ) tetrachloride with tetrabutyltin, which was obtained through Grignard reaction in the mixture of THF and tolaruene, followed by hydrolysis of the yielded crude dibutyltin dichloride.
