Fluorine-containing phenyl benzoate compounds, and their production and use

Abstract

Fluorine-containing phenyl benzoate compounds which have the general formula: ##STR1## wherein R is a C.sub.1 -C.sub.12 perfluoroalkyl group, a C.sub.1 -C.sub.12 alkyl group, a C.sub.1 -C.sub.12 alkoxy group, a C.sub.2 -C.sub.13 alkanoyloxy group, a C.sub.2 -C.sub.13 alkoxycarbonyl group, a C.sub.2 -C.sub.13 alkoxycarbonyloxy group or a C.sub.2 -C.sub.13 alkyldioxycarbonyl group and X is a C.sub.1 -C.sub.12 alkyl group, a C.sub.1 -C.sub.12 alkoxy group, a cyano group, a trifluoromethyl group or a nitro group with the proviso that X is trifluoromethyl when R is other than perfluoroalkyl are useful as components of liquid crystals.
