摘　　要：以费托蜡为中心,通过改性、调和生产高附加值特种蜡,是我国费托蜡工业未来的发展方向。对费托蜡的无催化氧化的改性工艺条件以及引发剂的作用原理进行了研究,考察了反应温度、反应时间、氧气流量等因素对氧化蜡酸值、皂化值的影响。结果表明,最佳实验条件为:反应温度160℃、反应时间6 h、氧气流量400 mL/min,在该条件下制得的氧化蜡酸值可达40.51 mg(KOH)/g,皂化值可达86.50 mg(KOH)/g;引发剂的加入在一定程度上加快了氧化反应的速度,其中以硬脂酸为引发剂更适宜大规模的工业应用。The future development direction of China's Fischer Tropsch wax industry is to produce high value-added special wax by modification and blending centered on Fischer Tropsch wax.The modification process conditions of Fischer Tropsch wax without catalytic oxidation and the action principle of initiator were studied.The effects of reaction temperature,reaction time and oxygen flow on the acid value and saponification value of oxidized wax were investigated.The optimum experimental conditions are:reaction temperature 160℃,reaction time 6 h and oxygen flow 400 mL/min.Under these conditions,the acid value of oxidized wax can reach 40.51 mg(KOH)/g and saponification value can reach 86.50 mg(KOH)/g.The addition of initiator accelerates the oxidation reaction to a certain extent,and stearic acid as initiator is more suitable for large-scale industrial application.
