氯磺酸制备脂肪酸甲酯磺酸盐的研究

Study on Preparing for Sodium α-Sulfo Fatty Acid Methyl Ester(MES)with Chlorosulfonic Acid

介绍了一种以氯磺酸为磺化剂，在无溶剂下制备棕榈酸甲酯磺酸盐的方法。其方法是：以棕榈酸甲酯为原料，氯磺酸为磺化剂，经无溶剂磺化反应、老化反应，中和、干燥后处理制备得到棕榈酸甲酯磺酸盐。经正交优化试验和重复性试验得到最佳的制备条件为：物质的量之比1：1．2、磺化时间60min、老化时间35min、氮气流量42L／h，得到的活性物含量为62％～65％。

A new technique on preparing of sodiumα -sulfo palm fatty acid methyl ester（MES） with chlorosulfonic acid as sulfonating agent was introduced. The specific method was methyl palmitate as raw material, under solvent -free condition, MES was obtained through sulfonation reaction, aging reaction, and then neutralization, drying post - processing. The best preparation conditions was got through the orthogonal optimization experiments and repetitive tests, as follows： the amount of substance ratio 1 ： 1.2, the sulfonation time 60min, the aging time 35min, the nitrogen flow 42 L/h, and active products content of 62% ~65%.
