摘　　要：以单因素试验为基础,结合多元线性回归研究了不同因素对脂肪醇聚氧乙烯醚硫酸钠(AES)中二噁烷含量的影响。结果表明:贮藏期间,AES产品中的二噁烷含量与EO数、温度、pH值和时间呈正相关,即随着EO数的增加,温度的升高,pH值的增大和时间的延长,AES中的二噁烷含量均增加;采用多元线性回归分析各因素对二噁烷含量的影响,影响程度为:EO数>pH值>时间>温度;光照对二噁烷含量的增长具有一定的影响,但影响程度较小。Based on the results obtained from single factor experiments and in combination with multiple linear regressions,the influences of different factors on the content of dioxane in sodium fatty alcohol ether sulphate(AES)were investigated.The results show that the dioxane content in AES is positively correlated with EO number,temperature,pH and time during storage,i.e.,more dioxane exists in the case of larger EO number,higher temperature,higher pH or longer time.According to the analysis with multiple linear regression,the contributions of the 4 factors to the increase of dioxane in AES are ranked as follows:EO number>pH>time>temperature.Sunshine has a slight influence on the increase of dioxane content.
