STN液晶中间体的合成综述

Discussion of Intermediate Synthesis in STN Liquid Crystal

本文综述了合成三种STN液晶中间体的合成方法,并较详细地介绍了作者合成烷基苯乙酮、烷基苯甲酸和烷基环已基甲酸的实验方法及结论。三种中间体用测定沸点、熔点、质谱、核磁共振等方法确定了结构,并用色谱测定了产品纯度超过了98.7％。

In this paper,the synthetic methods of three kinds of inportant intermediates for STN Liquid crystal have been in troduced,the authors detailed introduced their methods and con-clusins of experimentations for synthesizing 4-n-alkylacteophenones, 4 - n-alkylcyclo-hexane - 1-carboxylic acids and 4-n-alkylbenzoic acids. The structures of all products were checked and confirmed by Bp. Mp. Ms and NMR. The purity of the intermediates for STN liquid cuystal measured by GC were over 98. 7%.
