摘    要:对石蜡无催化剂氧化改性的工艺条件进行了研究,考察了空气流量、氧化引发剂的质量分数、反应温度和反应时间对石蜡氧化过程的影响及反应条件对氧化石蜡性质的影响。结果表明,在不添加任何催化剂的前提下,选取适当的反应条件,可以得到色泽好、味道轻、酸值高的氧化石蜡产品;反应温度和反应时间是影响石蜡氧化反应和氧化石蜡性质的重要因素。若要获得理想的氧化反应速率,反应温度通常在150~155℃之间,反应时间一般在6~8h之间。由于采用无催化剂氧化改性,产物无须分离提纯,质量稳定;生产出的氧化石蜡能满足多种特种蜡的配方要求,尤其是在配制乳化蜡时,在外观、粘度、稳定性等方面都取得了较佳的效果。

关 键 词:石蜡  氧化  改性

Abstract:The process conditions of oxidation modify of paraffin waxes without using catalysts were investigated. Influences of air flow rate, mass fraction of oxidation initiating agent, reaction temperature and reaction time on the oxidation process and properties of paraffin waxes were studied. The results show that under proper conditions without using catalysts, the oxidized product with better tint, less smell and high acid number are obtained. Reaction temperature and reaction time are important factors, which affect oxidation process of paraffin waxes and properties of oxidized paraffin waxes. The optimal oxidation rate would be obtained when reaction temperature is at 150~155 ℃, optimal reaction time is 6~8 hours. In the oxidation absence of catalyst, there is no necessary to purify the oxidized product and its quality is stable. Oxidized paraffin waxes obtained from this process can satisfy the formula of many special waxes, especially using them to prepare emulsifying wax, the appearance, viscosity and stability of emulsion is good.
Keywords:Paraffin wax  Oxidation  Modify
