摘　　要：通过后交联反应制备了经偏苯三甲酸酐化学修饰的富羧类吸附树脂(命名为FZH124),通过FT-IR、比表面及孔径分析对其结构进行表征。在探讨FZH124对水中苯酚、尿囊素及5-对羟基苯基乙内酰脲(HPHI)的静态吸附效率的基础上,提出了合成5-对羟基苯基乙内酰脲的催化效果,并以FZH124为催化剂,以苯酚、尿囊素为原料,水体系下一步催化合成了5-对羟基苯基乙内酰脲,采用高效液相色谱及质谱进行了确认和标定。The multicarboxyl resins(named FZH124) modified with trimellitic anhydride by post-crosslinking reaction were prepared and characterized by FT-IR and BET. The possible catalytic effect for synthesis of 5-p-hydroxyphenyl hydantoin was proposed after investigating the static adsorption performance of phenol, allantoin and 5-(4-hydroxyphenyl)hydantoin on FZH124 from aqueous solution. 5-(4-Hydroxyphenyl)hydantoin was synthesized by reaction of phenol and allantois with FZH124 as catalyst in aqueous. And the final product was confirmed and demarcated by HPLC and MS.
