studies on the kinetics of reaction of 1 mol of parabanic acid (imidazolidine-2,4,5-trione) with 1 mol of ethylene oxide (oxirane) or propylene oxide (2-methyloxirane) carried out in the presence of triethylamine catalyst in dimethylsulfoxide solution are presented. A rate equation describing the reaction is presented and the mechanism proposed. The validity of the proposed mechanism is proved by instrumental
在三乙胺存在下对 1 mol 对羟基苯甲酸 (imidazolidine-2,4,5-trione) 与 1 mol 环氧乙烷 (oxirane) 或环氧丙烷 (2-methyloxirane) 反应动力学的研究结果介绍了在二甲亚砜溶液中的催化剂。给出了描述反应的速率方程并提出了机理。通过仪器分析方法证明了所提出机制的有效性。还介绍了温度的影响并评估了反应的热力学参数。© 2002 Wiley Periodicals, Inc. Int J Chem Kinet 35: 73–80, 2003
