【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。更多还原

【Abstract】 The content of 1,4-dioxane in narrow-distribution sodium fatty alcohol ether sulfate（narrowdistribution 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.更多还原
