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
