摘　　要：以三氯化铝为催化剂，环氧氯丙烷、磷酸为原料合成了磷酸单（１－氯－２－羟基丙基）酯并以磷酸单（１－氯－２－羟基丙基）酯和三氧化二锑为原料合成了其锑合物。实验结果表明，以甲苯为溶剂，在反应温度为９０℃，时间２ ｈ，原料配比为ｎ（环氧氯丙烷）∶ｎ（磷酸）＝ １∶１．２ 条件下，酯的收率为８２．５％ 。锑合物的合成条件为：温度９２℃，反应时间为４ ｈ，以二甲亚砜为溶剂，产品收率为８５．６％ 。Mono (1 chloro 2 hydroxy propyl) phosphate is synthesized from epichlorohydrin and phosphoric acid with toluene as solvent and AlCl 3 as catalyst at a temperature of 90℃ for 4 hours. The normal ratio of epichlorohydrin to phosphoric acid is 1∶1.2, and the total yield can reach 82.5%. Antimony trioxide and the ester are used as raw materials to synthesize antimony mono (1 chloro 2 hydroxypropyl) phosphate with dimethyl sulfoxide as solvent and oxalic acid as catalyst at a temperature of 92℃ for 4 hours, and the total yield can reach 85.6%.
