摘要: 以硬脂酸为主要原料,在85℃下,用浓硫酸对硬脂酸进行磺化,恒温反应6h,制得α磺化硬脂酸。用水/丙酮提纯后与氢氧化钠反应,得到双亲水基阴离子型表面活性剂。红外光谱初步确定其结构,实验表明,该目标物水溶液的CMC和〖WTHX〗γ〖WTBZ〗 CMC低于SDS,具有较高的表面活性;同时有良好的起泡和稳泡性能。具有理论意义和实用价值。

Abstract: Amphiphilic anionic surfactant is produced through following measure: Take stearic acid as main raw material, and then make sulfornation by battery acid at 85℃. reaction time is 6 hour. then the product is purified with water/acetone, in the end, reacted with NaOH again. Infrared spectrum preliminarily makes sure its structure.This experiment shows that target′s aqueous solutions are of lower CMC and γ CMC than SDS′s and higher surface activity, in the meantime, latherability and foam stability.

Key words: stearic acid, sulfonation, critical micelle concentration, latherability, foam stability
