Title:
ESTER DERIVATIVE OF 3-CHLORO-6-HYDROXYPYRIDINE
Document Type and Number:
Japanese Patent JPS58121272
Kind Code:
A
Abstract:
NEW MATERIAL:The compound of formulaI(X is 1W10C alkyl or alkoxy; the ring Y is group of formula II, III, IV or V or phenylene).
EXAMPLE: trans- 4-( trans-4'-Propylcyclohexyl )cyclohexanecarboxylic acid 3-chloro-6-pyridyl ester.
USE: A liquid crystal compound. In spite of the low dielectric anisotropy, the compound exhibits broad nematic temperature range and high stability to moisture, light and heat without too much increase in the threshold voltage and saturation voltage.
PROCESS: The compound of formulaIis prepared by reacting a carboxylic acid corresponding to the objective compound with thionyl chloride, and reacting the resultant carboxylic acid chloride with 3-chloro-6-hydroxypyridine in the presence of pyridine.
