摘　　要：采用H2O2为引发剂,考察了反应温度、反应时间、引发剂加入量、空气流量和搅拌速度等因素对氧化石蜡酸值的影响,结果表明,搅拌速度和空气流量影响不大;当引发剂加入量为5%,反应温度为150℃,反应时间为8 h,空气流量为200 mL/min时,石蜡经氧化后酸值可达到32.1 mg KOH/g。经与硬脂酸作为引发剂进行比较,该改性氧化蜡具有颜色浅、气味轻等优点,可以替代天然蜂蜡制成性质稳定的乳化蜡。Using H2O2 as an initiator,the effects of reaction temperature,reaction time,initiator dosage,air flow and stirring speed on the acid value of oxidized paraffin wax were investigated.The results showed that the stirring speed and air flow are little effect on the reaction.When the concentration of initiator is 5%,reaction temperature is 150 ℃,reaction time is 8 h,air flow is 200 mL/min,the oxidized paraffin wax with acid value of 32.1 mg KOH/g can be achieved.Compared with the stearic acid as the initiator,the modified oxidized paraffin wax is light color and less smell,it can be used to produce stable emulsion wax replacing natural bee-wax.
