摘　　要：以漆蜡为原料,经甲酯化后以氯磺酸为磺化剂,双氧水为漂白剂制备漆蜡脂肪酸甲酯磺酸盐,研究了最佳制备工艺条件,并对漆蜡脂肪酸甲酯磺酸盐的性能进行了研究。试验得到漆蜡脂肪酸甲酯磺酸盐最佳制备工艺条件为:漆蜡脂肪酸甲酯与氯磺酸摩尔比1∶1.2,磺化时间40 min,老化时间45 min;在最佳制备工艺条件下的漆蜡脂肪酸甲酯磺酸盐含量最高,为40.1%,二钠盐含量为18.5%;经纯化后,漆蜡脂肪酸甲酯磺酸盐含量为78.0%,二钠盐含量为3.2%。漆蜡脂肪酸甲酯磺酸盐临界胶束浓度为0.7×10-3mol/L,表面张力为39 mN/m;在其水溶液质量分数为0.1%时,分出5 mL水的时间为60 s;漆蜡脂肪酸甲酯磺酸盐的发泡能力为65 mm,静置5 min后,泡沫高度降为50 mm。Fatty acid methyl ester was prepared by esterification of lacquer wax and methanol, then the fatty acid methyl ester sulfonate （MES）was prepared by lacquer wax fatty acid methyl ester and chlorosulfonic acid with hydrogen peroxide as bleaching agent, and the optimal preparation conditions and properties of lacquer wax - based MES were researched. The optimal preparation conditions of lacquer wax - based MES were obtained as follows： molar ratio of lacquer wax fatty acid methyl ester to chlorosulfonic acid 1 ： 1.2, sulfonation time 40 min and aging time 45 min. Under these conditions, the contents of the lacquer wax -based MES and disodium salt were the highest, reaching 40.1% and 18.5% respectively, and their contents were 78.0% and 3.2% respectively after purification. The critical micelle concentration of the lacquer wax - based MES was 0.7 × 10^-3 mol/L,and the surface tension reached 39 mN/m.When the mass fraction of lacquer wax - based MES solution was 0.1% , it could separate 5 mL water in 60 s. The foaming capacity of the lacquer wax - based MES was 6 5 mm , and the foam height was down to 50 mm after standing for 5 min.
