摘要
在氯仿体系中,以氢化棕榈酸甲酯为原料、氯磺酸为磺化剂,通过磺化、老化、中和、干燥后制得氢化棕榈酸甲酯磺酸盐。经单因素及正交实验优化得到最佳工艺条件:滴加温度40℃,氯仿与甲酯质量比2.0∶1.0,氯磺酸与甲酯物质的量比1.55∶1.0,磺化时间60 min,老化时间70 min。在最佳工艺条件下,制备的产品颜色呈淡黄色,氢化棕榈酸甲酯磺酸盐的含量为64.36%。
Hydrogenated palmitinic acid methyl ester sulfonate was synthesized through sulfonation reac- tion, aging reaction, neutralization and drying process using hydrogenated palmitinic acid methyl ester as raw materials, chlorosulfonic acid as sulfonating agent in trichloromethane system. The optimal conditions were approached through single factor experiments and the orthogonal experiments as follows：dropping temperature 40 ℃ ,mass ratio of chloroform and methyl palmitate 2.0 ： 1. 0, molar ratio of chlorsulfonic acid and methyl palmitate 1.55： 1.0, sulfonation time 60 min, aging time 70 rain. Under the optimal con- ditions, the content of hydrogenated palmitinic acid methyl ester sulfonate was 64.36% and the colour of product was light yellow.
