摘要
本文介绍了用传统催化剂提高失水山梨醇单油酸酯(Span-80)质量的实践、所选定的醚化催化剂浓度、醚化温度和醚化时间与有关资料上介绍的有较大的差别。大生产中制得的Span-80各项指标均符合国家行业标准,外观色泽及其它有关数据与国外产品相似。
In this paper, traditional catalyst had been used to improve quality of sorbitan monoloeate was introduced the concentration of catalyst choosed , temperature and time of etherifiation different from that report- ed in other paper. Span-80 prepared,in this way,correspond to national industrial standard, it's color and other data as product of other country.
