Abstract

NEW MATERIAL:A 2,3-dicyano-p-hydroquinonecyclohexanecarboxylic ester of the formula (R1 and R2 are H, 1-10C alkyl or alkyloxy groups).
EXAMPLE: 2,3-Dicyans-1,4-bis (trans-4-octylcyclohexylcarboxy) benzene.
USE: Liquid crystal materials having a large negative dielectric anisotropy useful for light scattering or DAP type liquid crystal display units and guest-host type color display units, without degrading the optical stability of the well-known practical liquid crystals.
PROCESS: Cyclohexanecarboxylic acid or its trans-4-alkyl or alkoxy derivative is chlorinated. Two moles of the chlorination product is reacted with one mole of 2,3-dicyano-1,4-hydroquinone in a basic solvent to give the objective compound of formula I.
