摘要:

在实验室三氧化硫降膜式硫酸化装置上,分别以n(SO3)∶n(窄分布脂肪醇醚(AEO))、硫酸化温度、SO3体积分数、脂肪醇醚硫酸酯放置时间和中和温度为单因素变量,研究了窄分布脂肪醇醚硫酸盐(窄分布AES)产品中二噁烷的含量变化。结果表明:随着体系中n(SO3)∶n(窄分布AEO)的增加、硫酸化温度的升高、SO3体积分数的升高、脂肪醇醚硫酸酯放置时间的延长和中和温度的升高,窄分布AES中二噁烷的含量增加。

关键词: 三氧化硫, 窄分布脂肪醇醚硫酸盐, 二噁烷

Abstract:

The content of 1,4-dioxane in narrow-distribution sodium fatty alcohol ether sulfate (narrow-distribution AES) was studied by using n(SO3)∶n(narrow-distribution fatty alcohol ether), sulfation temperature, volume fraction of SO3, storage time and neutralization temperature as single-factor variables on a laboratory device of sulfur trioxide falling film sulfation. The results showed that, the content of 1,4-dioxane in narrow-distribution AES would increase with the increase of excess SO3, sulfation temperature, volume fraction of SO3, storage time of narrow-distribution fatty alcohol ether, and neutralization temperature.

Key words: sulfur trioxide, narrow-distribution sodium fatty alcohol ether sulfate, 1,4-dioxane
