Abstract
NEW MATERIAL:4-n-Alkylbiphenylcarboxylic acid 2-chloro-4-n-alkylphenyl ester of formula I (R and R' are 2W8C alkyl).
EXAMPLE: 4-n-Peptylbiphenylcarboxylic acid 2-chloro-4-n-butylphenyl ester.
USE: Liquid crystal material for double frequency driving or for the element of a positive guest-host display effective to raise the clear point, and the range of the liquid crystal temperature can be easily widened. The dispersion frequency is rather low considering the low viscosity of the compound. It has high chemical stability.
PROCESS: 4-n-Alkyl-4'-cyanobiphenyl of formula II is subjected to the thermal reaction with an aqueous solution of KOH in ethylene glycol to afford 4-(p-n-alkylphenyl) benzoic acid, which is then made to react with SOCl2 to give a benzoic acid chloride. This compound is esterified with 2-chloro-4-n-alkylphenol of formula III to give the compound of formula I.
