摘要： The invention relates to a process of preparing glycol carboxyethylmethylphosphinate, which comprises a) reacting elemental yellow phosphorus with methyl chloride in the presence of an alkali or alkaline earth metal hydroxide to form a mixture which includes the alkali and/or alkaline earth metal salts of methylphosphonous, phosphorous and hypophosphorous acids as main constituents, b) esterifying the methylphosphonous acid from the mixture obtained by a), c) removing the methylphosphonous ester from the mixture, d) adding the thus obtained methylphosphonous ester to an acrylic ester, e) hydrolyzing the diester thus obtained, f) esterifying the resulting carboxyethylmethylphosphinic acid with ethylene glycol directly to the glycol carboxyethylmethylphosphinate. The invention also relates to the use of the glycol carboxyethylmethylphosphinates prepared according to the invention as reactive flame retardants for polymers.
摘要翻译：本发明涉及一种制备二羧酸乙基甲基次膦酸二甲酯的方法，该方法包括：a）在碱金属或碱土金属氢氧化物存在下，使元素黄磷与氯甲烷反应形成一种混合物，该混合物包括甲基亚磷酸的碱金属和/或碱土金属盐，磷和次磷酸作为主要成分，b）从a）中得到的混合物中酯化甲基亚膦酸，c）从混合物中除去甲基亚膦酸酯，d）将得到的甲基亚膦酸酯加入到丙烯酸酯中，e）水解二酯 f）将得到的羧乙基甲基次膦酸与乙二醇直接酯化至二羧酸乙乙基甲基次膦酸酯。本发明还涉及根据本发明制备的二羧酸乙基甲基次膦酸酯作为聚合物的反应性阻燃剂。
