二丁基马来酸锡制备

(1)氧化二丁基锡的合成常温下将红磷、丁醇投入反应釜，然后分批加入碘，边加边搅拌，随着反应的进行，温度逐渐升高，当温度达到127℃左右时，停止反应。加水洗涤，静置分层。分去水层，油层进行分馏，得精制碘丁烷。将碘丁烷、溶剂正丁醇及锡粉、镁屑加入反应釜，在强烈搅拌下于120～140℃进行反应。达到终点后进行蒸馏，回收正丁醇和未反应的碘丁烷。釜液为碘代丁基锡粗品。加入10%的盐酸，控制温度60～70℃搅拌洗涤半小时，静置分层，分出废酸液，得精制二碘代二正丁基锡。将20%的烧碱溶液加入到二碘代二正丁基锡中，搅拌下控制温度60℃左右，进行水解反应。水解完成后，静置分层，分去水层后，用水洗涤，获精制氧化二正丁基锡。

(2)成品的制备将氧化二丁基锡和马来酸酐加入反应釜，在搅拌下控制温度于60～70℃下，进行缩合反应。反应产物经减压脱水、压滤，即得成品。
