摘要

研究了在 Mo2B 存在下丙烯酸乙烯烯丙酯与过氧化氢叔丁酯发生环氧化反应时催化剂活化过程的动力学规律。研究表明,催化剂的活化过程发生在环氧化过程的开始阶段,主要是在过氧化氢叔丁酯和烯烃的同时作用下进行的。未活化催化剂与反应物和反应产物生成复合物的能力明显低于活化催化剂,环氧化物的形成实际上只发生在活化催化剂上。研究表明,催化剂活化过程可以用 Avrami-Yerofeev 拓扑化学方程式来描述,并包括两个连续阶段--成核和在环氧化反应中形成新的活性相。

STUDY OF THE CATALYTIC ACTIVITY OF Mo2B IN THE REACTION OF β-ETHYL ALLYL-α-ETHYL ACRYLATE WITH tert-BUTYL HYDROPEROXIDE
Kinetic regularities of catalyst activation processes in the reaction of epoxidation of ethylallyl ethyl acrylate with tert-butyl hydroperoxide in the presence of Mo2B were investigated. It is shown that the activation of the catalyst, which takes place at the beginning of the epoxidation process, mainly occurs under the simultaneous action of tert-butyl hydroperoxide and olefin. The ability to create complex with reactants and reaction products for the unactivated catalyst is significantly lower than for the activated one, and the formation of epoxide occurs practically only on the activated form of the catalyst. It is shown that the catalyst activation process can be described by the Avrami-Yerofeev topochemical equation and includes two successive stages – nucleation and formation of a new phase active in the epoxidation reaction.
