摘要: 维生素E是一种具有良好生理活性和药理价值的抗氧化剂,市场需求量不断增长,目前人们获得维生素E的80%来自于合成产品。对合成工艺进行改进,制备高纯度的合成维生素E产品,具有广阔的发展前景。本文简要阐述了合成维生素E的两种原料三甲基氢醌及异植物醇的制备方法,着重介绍了合成维生素E的催化体系与溶剂体系,并对存在的问题及研究发展前景进行了评述。Abstract: Vitamin E is a kind of antioxidant with good biological activity and medical functions. The demand for the vitamin E product on the market is constantly increasing. Currently 80% of vitamin E that people acquired is from synthetic product, so there is a broad development prospect for improving synthetic process and producing vitamin E product with high purity. In this paper, the preparation methods of trimethylhydroquinone and isophytol, which were materials for the synthesis of vitamin E, were briefly introduced. The research progress of new catalyst systems and new solvent systems were summarized. In addition, the existed problems and development prospect of the synthetic process were also commented.
