有的品种已实现了量产。

Abstract

A series of 2-amino-4-alkylphenol were synthesized by reduction of 4-alkyl-2-nitrophenol which was synthesized from alkyl-phenol. In the presence of polyphoshoric acid

2-amino-4-alkylphenol reacted with alkyl benzonirtrile to yield 2

5-disubstuted benzoxazole

a series of liquid crystalline compounds were synthesized. The structures of products were calibrated

the parameters of liquid crystal were measured and the performances of liquid crystal were studied. Some of the products achieved mass production

good effect was obtained.
