1,2-己二醇合成技术及应用进展

Synthesis and Application Progress on 1,2-hexanediol

1,2-己二醇因其良好的溶解性、无腐蚀性、抗菌和保湿等性能,被用于精细化工(如化妆品、高级油墨、高级油漆、高级胶水等)和医药等行业。近几年我国1,2-己二醇的使用量在不断增加,但1,2-己二醇在国内的生产企业很少,目前大多依赖进口。1,2-己二醇的合成一般以1-己烯为起始物,经氧化剂环氧化和水解两个过程生成1,2-己二醇。主要根据氧化剂的不同对1,2-己二醇的合成反应进行了分类介绍,涉及不同催化剂的催化效果;同时简单介绍了1,2-己二醇在工业上的应用。

1,2-hexanediol is used in fine chemical industry （such as additives of cosmetics, printing ink, paints andcoatings, senior glue, etc. ） and pharmaceutical industry due to its good solubility, non - corrosiveness, antimicrobialactivity and moisture retention property, etc. In recent years, the consumption of 1,2-hexanediol in our country has beenincreasing. However, there are few enterprises in the domestic production of 1,2-hexanediol and the gap between supplyand demand depends on imports. Usually, 1-hexene is used as the starting material, and after two processes-epoxidationby oxidant and hydrolysis, 1,2 -hexanediol is then produced. The synthesis of 1,2 -hexanediol was introduced mainlyaccording to different kinds of oxidants. Meanwhile, the catalytic effects of different catalysts were discussed, theindustrial application of 1,2-hexanediol was also briefly introduced.
