Abstract
Abstract NEW MATERIAL:A p-(beta-alkyloxy)ethylbenzoic p'-cyanophenyl ester of the formula (R is 1-6C straight-chain alkyl; X is H, C1). EXAMPLE:p'-Cyanophenyl p-(beta-propyloxy)ethylbenzoate. USE:A constituent of nematic liquid crystal materials with positive dielectric anisotropy. PREPARATION:The reaction of p-(beta-alkoxy)ethylbenzoic acid with a chlorinating agent such as thionyl chloride or phosphorus pentachloride gives its acid chloride and the chloride is made to react with p-cyanophenol or p-cyano-m-chloro- phenol in a basic solvent such as pyridine to give the compound of the formula.
