尿囊素合成催化剂的比较研究

Study on the Efficiency of Catalysts for the Allantion Synthesis

:对比了以乙醛酸和尿素为原料合成尿囊素工艺中三种催化剂盐酸、磷钨酸、Fe2 O3-SO42 -的催化效果。结果表明 :尿囊素收率较高时 。

The efficiency of catalysts:hydrochloric acid ,H 7P(WO 7) 6·xH 2O,Fe 2O 3 SO 4 2- ,used to catalyze the synthesis of allantion by glyoxylic acid and urea, is studied, Is showed that all of them result in high yield of allantion.
