摘　　要：以三氯氧磷、1,2-丙二醇为原料制备了一种多羟基磷酸酯阻燃剂。讨论影响反应的主要因素。确定优化条件为以甲苯作为溶剂,三氯氧磷与1,2-丙二醇的摩尔比为1∶3.2,反应温度90℃,反应时间3 h,产品收率达82.8%。A reactive flame retardant of polyhydroxy phosphate was prepared using phosphorus oxychlo- ride and 1,2-propanediol as raw materials. This paper aims to discuss the main factors affecting the response. The optimum conditions were determined as toluene as a solvent, the molar ratio of phosphorus oxychloride to 1,2-propanediol was 1 ： 3.2, the reaction temperature was 90℃, the reaction lasted for 3 hours, as a result, the obtained product yield reached up to 82.8%.
