摘要
制得了二丁胺甲基膦酸－亚酸氢锆Ｚｒ（ＨＰＯ３）２－ｘ·（Ｏ３ＰＣＨ２ＮＢｕ２）ｘ·Ｈ２Ｏ（ｘ＝０．８，０．６，０．５，０．４，０．３５），用溴化苄季铵化，得部分季铵化产物：溴化节基二丁铵甲基膦酸－二丁胺甲基膦酸－亚磷酸氢锆Ｚｒ（ＨＰＯ３）２－ｘ·（Ｏ３ＰＣＨ２ＮＢｕ２）ｘ－ｙ·（Ｏ３ＰＣＨ２Ｎ－Ｂｕ２·ＣＨ２Ｐｈ·Ｂｒ－）ｙ·Ｈ２Ｏ（ｙ＜ｘ），用作相转移催化剂，对液／固／液或固／固／液相转移催化的取代、成醚、合成酯及二氯卡宾加成反应均具良好的催化活性。催化剂易回收，回收率为７０％～１００％，重复使用１０次以上无明显失活。
Zirconium dibutylaminomethylphosphonate-phosphites Zr(HPO3)2-x·(O3PCH2N-Bu2)x·H2O(ZPDBN-ZP,x=0.8,0.6,0.5,0.4,0. 35)have been prepared for the firsttime. Partly quaternized ZPDBN-ZP with benzylbromide, zirconium(benzyldibutylammo-niomethylphosphonate bromide-dibutylammoniomethylphosphonate-phosphite)Zr(HPO3)2-x·(O3PCH2NBu2)x-y·(O3PCH2N+Bu2PhCH2Br-)y·H2O(ZPBBDB-ZPDBN-ZP,y<x)have been obtained. Heterogeneous PTC reactions of nucleophilic substitution, etherifica-tion,esterification, and addition of dichlorocarbene by using ZPBBDB-ZPDBN-ZP have beencarried out successfully. The catalysts can easily be recovered with recovery of 70%～100%. No obvious loss of the catalytic activity was found after more than ten times repeated use.
