摘要
采用了新型的失水催化剂，利用分步催化工艺合成了优质的Ｓｐａｎ－８０，考察了分步催化中失水和酯化反应的相互依赖关系及其对产品质量的影响。
Abstract The high quality products of Span-80were prepared by the continuous two-stepcatalysis reaction ,in which new antioxidantcatalysts had been used in the deliveration.The relationship between dehydration and es-terification,as well as their effects on the qual-ity of products were studied.
