Abstract

The consumption of styrene epoxide (SE) and hydroquinone (HQ) in a ternary system (TrS) (SE–HQ–Cu(II)) in an oxygen atmosphere in a methanol solution is studied. The oxygen uptake by the SE–HQ–CuCl₂ Trs is studied manometrically. The expression of velocity in terms of the reagent concentrations V = k[Cu(II)]¹[HQ]⁰[SE]⁰ and the effective oxidation rate constant k = 1.82 × 10⁵exp(–40 kJ mol^–1/RT) s^–1 is obtained in the temperature range 308–323 K. The oxidation mechanism of the TrS is discussed.

环氧苯乙烯-对苯二酚-氯化铜三元体系在甲醇溶液中的氧化反应

研究了三元体系（TrS）（SE - HQ - cu (II)）在甲醇溶液中氧气氛下环氧苯乙烯（SE）和对苯二酚（HQ）的消耗。用压力计研究了SE-HQ-CuCl2 Trs的吸氧性能。在308 ~ 323 k的温度范围内，反应速度用试剂浓度表示为V = k[Cu(II)]1[HQ]0[SE]0，有效氧化速率常数k = 1.82 × 105exp(-40 kJ mol-1 /RT) s-1。讨论了TrS的氧化机理。
