Abstract
NEW MATERIAL:A 3'-chloro-4'-cyanophenyl-4-( β-alkoxyethoxy )benzoate expressed by formulaI(R is 1W10C alkyl).
EXAMPLE: 3'-Chloro-4'-cyanophenyl-4-(β-propoxyethoxy)benzoate.
USE: A liquid crystal additive, having a high positive dielectric anisotropy, and particularly effective for giving a p type liquid crystal composition having a low viscosity by adding to an n type liquid crystal composition having a low viscosity.
PROCESS: A 4-(β-alkoxyethoxy)benzoyl chloride is reacted with a 3'-chloro-4- cyanophenol in the presence of pyridine to give the compound expressed by formulaI.
