4′-庚氧基-4-联苯甲酸的合成

Synthesis of 4′ heptoxybiphenyl 4 carboxylic acid

改进了４′－庚氧基－４－联苯甲酸的合成路线。经元素分析、ＩＲ、１ＨＮＭＲ和ＭＳ确证了中间产物４′－庚氧基－４－乙酰基联苯的结构。ＤＳＣ及织构图证实其具有液晶性。

An improved synthetic route for 4′ heptoxybiphenyl 4 carboxylic acid was studied. The structure of the intermediate,4 acetyl 4′ heptoxybiphenyl, was confirmed by elemental analysis, IR, 1HNMR and MS,and its mesomorphic property was determined by DSC and optical microscopy.
