摘要

环己烷苯类液晶是TFT液晶、高档第一极小TN和STN类混晶中常用的单体

杂质的存在对混合液晶电阻率、清亮点、低温性能有很大的影响。文章用不同极性的色谱柱对环己烷苯类液晶中的顺反产物进行分离

寻找到最佳的检测柱和最佳检测方法

并结合GC-MS手段对产品顺式定性。

Abstract

The hexamethylene alkyl benzene liquid crystal monomers are used in the Thin Film Transistor (TFT) liquid crystal

the first grade tiny Twisted Nematic (TN) and the Super Twisted Nematic (STN). The impurity affects resistivity

clearing points and the low temperature property of the mix liquid crystal a lot. In this work

the different polar gas chromatographic column and reversed-phase liquid chromatographic column are used to separate the cis-trans production to find the best column and the optimal analytical method. GC-MS is also used to determine the cis-product qualitatively.
