一种双亚磷酸三(3,3’-二甲基-5,5’-二叔丁基-2,2’-联苯酚)酯的微波合成方法
摘要：
本发明公开了一种双亚磷酸三(3,3’-二甲基-5,5’-二叔丁基-2,2’-联苯酚)酯的微波合成方法，该方法以摩尔比为1:1-10:1的亚磷酸三烷基酯与3,3’-二甲基-5,5’-二叔丁基-2,2’-联苯酚为原料，芳基取代氯化磷或烷基取代氯化磷为催化剂，无溶剂微波辐射条件下合成双亚磷酸三(3,3’-二甲基-5,5’-二叔丁基-2,2’-联苯酚)酯，微波辐射功率为100-1000w，微波反应时间为5-30分钟。本发明工艺具有双亚磷酸酯产率高、副产物少、反应时间短、无溶剂操作、环境友好无污染、后处理简单等特点。
摘要（英）：

The invention discloses a bis-phosphorous acid triphenyl (3,3'-tetra-dimethyl-5,5'-di-tert-butyl-2,2'-xenol) ester microwave synthesis method. According to the method, phosphorous acid trialkyl ester and 3,3'-tetra-dimethyl-5,5'-di-tert-butyl-2,2'-xenol are used as raw materials, wherein the molar ratio of the phosphorous acid trialkyl ester and the 3,3'-tetra-dimethyl-5,5'-di-tert-butyl-2,2'-xenol is 1:1-10:1; aryl substitute phosphoric chloride or alkyl substitute phosphoric chloride serves as a catalyst; bis-phosphorous acid triphenyl (3,3'-tetra-dimethyl-5,5'-di-tert-butyl-2,2'-xenol) ester is formed by synthesis under microwave radiation without solvent; microwave radiation power is 100-1000w, and microwave reaction time is 5-30min. The method has the advantages of being high in bis-phosphite acid ester yield, small in number of by-products, short in reaction time, capable of achieving solvent-free operation, environmentally friendly, free of pollution, simple in aftertreatment and the like.
