摘要
以棕榈油为原料,通过酯交换反应、硫酸化改性制备皮革加脂剂。采用正交试验法优化的甲醇酯交换反应条件为:n(甲醇):n(棕榈油)=3:1,在65℃时加入催化剂甲醇钠0.5%(质量分数)反应1 h。此优化条件下引入羟基量适中,酯交换深度较好。对改性棕榈油进行硫酸化,当m(硫酸):m(改性棕榈油)=25%,在25～30℃温度下反应5 h,制得的加脂剂呈棕黄色,流动性较好,水乳液稳定性好。
Fat liquor was synthesized through esterification and sulfurication by palm oil as raw material.Through orthogonal test analysis,the optimum reaction conditions of esterification were that the molar ratio of alcohol to oil was 3：1,mass of catalyst was 0.5 percent of palm oil,reaction temperature was 65 ℃and reaction time was 1 h.The optimum reaction conditions of sulfurication were as following：mass of sulfuric acid to modified palm oil 25 %,reaction temperature 25 ~ 30 ℃,reaction time 5 h.Fat liquor agent obtained was the brown mobile liquid and its emulsion was steady,had no stratification and floating oil in 24 h.
