Abstract—

This paper describes oxidation of a ternary system (styrene epoxide (SE)—hydroquinone (Hq)—Cu(II) chloride) with oxygen in the solvent (tert-butanol/water (4 : 1 by volume)). The expression of the rate in the concentration: V = k[CuCl₂]¹[SE]⁰[Hq]⁰ at [SE] > [Hq] > [CuCl₂] is explained by the formation of the ternary complex, antecedent of oxidation. The effective rate constant of the oxidation is k [s^–1] = 92.5 exp (–22/RT) at 323–343 K. The ratio of concentration of absorbed oxygen to copper catalyst [O₂] /[CuCl₂] \( \gg \) 1, i.e., the oxidation is a catalytic reaction.

叔丁醇水溶液中环氧苯乙烯-对苯二酚-氯化铜（II）三元体系的催化氧吸收

摘要—

本文介绍了在溶剂（叔丁醇/水（体积比为4：1 ））中用氧气氧化三元体系（苯乙烯环氧化物（SE）-对苯二酚（Hq）-Cu（II）氯化物）的方法。在[SE]> [Hq]> [CuCl ₂ ]处浓度为V = k [CuCl ₂ ] ¹ [SE] ⁰ [Hq] ⁰时，速率的表达通过三元络合物的形成来解释。氧化。在323–343 K时，氧化的有效速率常数为k [s ^–1 ] = 92.5 exp（–22 / RT）。吸收的氧气与铜催化剂的浓度之比[O ₂ ] / [CuCl ₂ ]\（\ gg \） 1，即氧化是催化反应。
