Abstract

NEW MATERIAL:The compound of formula I (R and R' are 1W7C straight-chain alkyl; each of the two cyclohexane rings has trans-configuration).
EXAMPLE: The compound of formula II.
USE: A material for electro-optical display. It has high clear point and a wide intermediate-phase temperature range, and is useful as an additive to other nematic liquid crystal compounds or their mixture for extending its intermediate-phase temperature range to the high-temperature side. The viscosity increase of the resulted liquid crystal mixture can be suppressed to a considerably low level. It is chamically stable, does not decompose with water, light, etc., and is colorless.
PROCESS: Reaction of 4-trans-n-alkylcyclohexanecarbonyl chloride with p-hydroxybenzoic acid gives the compound of formula III, which is chlorinated to obtain the compound of formula IV. The compound of formula I can be obtained by reacting the compound of formula IV with 4-trans-n-alkylcyclohexanol in a basic inert solvent.
