α-磺基脂肪酸甲酯钠盐的性能研究

Study of property of sodium α-sulfo fatty acid methyl ester

考察了MES二钠盐质量分数随pH值和温度的变化,比较了MES与LAS、AOS、AES及Igepon-A等在洗衣粉、肥皂及香波中的应用性能,从而得出:pH值在3 5～9 0、温度80℃以下,MES具有良好的水解稳定性及优异的抗硬水能力,在高达1500×10-6mol·L-1硬度的硬水中,仍具有极强的去污力,在粉状、块状和液体洗涤剂中有良好的应用前景。

The connection of MES disodium content with pH and temperature was investigated.The application of MES in laundry detergent,soap and shampoo was compared with LAS,AOS,AES and Igepon-A.It was indicated that MES had good hydrolytic stability and excellent contra hard-water ability with pH 35～90 and under 80 ℃.Even in the hard-water(1 500×10-6 mol·L-1),MES had excellent detergency.So MES would have better application prospects.
