Abstract

NEW MATERIAL:A diester of 2,3-dichlorohydroquinone shown by the formula (the ring A and the ring B are cyclohexylene, phenylene; R1 and R2 are H, 1W8C alkyl, alkoxy).
EXAMPLE: 1,4-Bis(4-trans-benzylcyclohexylcarbonyloxy)2,3-dichlorobenzene.
USE: A liquid crystal substance having a negative dielectric anisotropy. Having a wide range of liquid crystal temperature, and excellent as a component for liquid crystal material because of its small rise in viscosity.
PROCESS: In a case of symmetric type diester a 4-substituted benzoic acid or trans-4-substituted cyclohexanecarboxylic acid is reacted with a chlorinating agent such as thionyl chloride to give an acid chloride, 2mol of this acid chloride is reacted with 1mol 2,3-dichlorohydroquinone in a basic solvent (e.g., pyridine), to give a symmetric type compound shown by the formula V.
