摘要： 分别采用电位滴定法、Ross-Miles泡沫仪、改进的酸滴定法和浊度法测试了脂肪酸甲酯磺酸盐(MES)的水解稳定性、发泡稳泡性能、钙皂分散力及Krafft点,并测试了含MES的洗衣液的稳定性和去污性能。结果表明,储存温度为45 ℃时,MES在pH=4.5~9.0时是稳定的,当pH达到10.0时,α-磺基脂肪酸二钠盐(DS)质量分数明显增加,水解现象较明显;MES对钙皂的分散力为2.5 g钙皂/gMES,LAS对钙皂的分散力为0.34 g钙皂/g LAS;MES的Krafft点约为20.9 ℃;含MES的洗衣液配方产品具有很好的稳定性,去污性能能达到国标要求。

Abstract: The hydrolytic stability,foaming power and foam stability,lime soap dispersing power and Krafft point of fatty acid methyl ester sulfonate (MES) were measured by potentiometric titration,Ross-Miles foam instrument,improved acidometric titration and turbidimetric test,respectively.The stability and detergency of the liquid detergent containing MES were also tested.The results show that when the storage temperature is 45 ℃,MES is stable at pH 4.5-9.0,however,when pH is 10.0,the mass fraction of disodium salt ofα-sulfonated fatty acid (DS) increases,indicative of obvious hydrolysis;MES shows excellent lime soap dispersing power with a value of 2.5 g calcium soap per gram of MES (In contrast,the value for LAS is 0.34 g calcium soap per gram of LAS);The Krafft point of MES is approximately 20.9 ℃;The liquid detergent products containing MES have excellent stability,and the detergency performance can meet the requirements of the national standard.

Key words: fatty acid methyl ester sulfonate, hydrolytic stability, lime soap dispersing power, liquid detergent
