Abstract
NEW MATERIAL:A compound of formulaI[X is R(R is 1W10C alkyl, alkoxy), group of formula II or formula III].
EXAMPLE: [4,-(4'-Methoxyphenyl) acetophenone oxim].
USE: A liquid crystal with positive dielectric anisotropy: it has a wide range of liquid crystal temperature, especially extending to high-temperature region. For example the compound in which X is C5H11 has 87°C C-S point, 119°C S-N point and 181°C N-I point and further show low viscosity at low temperature, thus being suitably used as a component of a liquid crystal composition for liquid crystal display elements operating in a wide temperature range.
PREPARATION: The reaction between the chloride of a carboxylic acid of formula IV and 4-fluoro-4'-hydroxy-biphenyl of formula V is effected in the presence of pyridine to produce the compound of formulaI.
