【摘要】 本文从自由基反应机理出发,系统地研究了甲基异丙苯氧化生成甲基异丙苯氢过氧化物、a,a-二甲基甲苯甲醇、甲基苯乙酮、异丙基苯甲酸的主、付反应动力学。建立了各反应的氧化速率方程式,求得各反应的表观反应速率常数及表观活化能。在[ROOH]<[ROOH]_max（～21%）时,用所得的K值计算各瞬间氧化液组成与实测相符。测定了甲基异丙苯各异构体的相对易氧化性为:o:m:p=1:2.15:2.43。更多还原

【Abstract】 The kinetics of oxidation of cymenes was studied.The oxidation products,including cymene hydrogen peroxide,α,α-dimethyl benzyl alcohol, methyl acetophenone and cumic acid were taken into consideration. The rate equations of the oxidation reactions were formulated and also the apparent rate constants and activation energies of reactions were estimated.The calculated compositions of oxidation products agreed with those experimentally determined when [ROOH]<[ROOH]_max （0-21%）. The ratio of oxidation rate of cymene isomers were o:m:p= 1:2,15:2,43,更多还原
