The esterification wax was synthesized by one-step oxygen oxidation and esterification process from mixed paraffin and microcrystalline with the mass ratio of 6:4. The results were compared with traditional air oxidation process. The kinetic models of the oxygen and air oxidation were established, respectively. The model parameters were obtained by linear regression of saponification values under different reaction temperatures The activation energy is 6.49 kJ/mol for oxygen oxidation and 11.56 KJ/mol for air oxidaomtion, while pre-exponent factor is 3.09 h-1 and 11.33 h-1, respectively. Compared with air oxidation, the product of oxygen oxidation possesses higher esterification number, less off-gas discharge and quicker reaction rate.%石蜡与微晶蜡质量比6∶4的混合原料,经纯氧氧化、酯化一步法合成高酯值蜡.与传统的空气氧化法进行了对比研究,并以皂化值为参数建立了两种氧化法的动力学模型.由不同反应温度下的实验数据回归得到氧气氧化反应的活化能为6.49 kJ/mol,指前因子为3.09h-1;空气氧化反应的活化能为11.56 kJ/mol,指前因子为11.33 h-1.研究表明,相对于空气氧化法,氧气氧化法具有产品酯化值高、尾气排放量少以及反应速率快的优点
