摘要： PROBLEM TO BE SOLVED: To obtain a container for storing a liquid material capable of preventing the deterioration of a liquid crystal compound containing fluorine atoms, etc., capable of maintaining a high specific resistance value, and suitable for carrying the liquid crystal by constituting a resin layer formed on the inner side brought into contact with the liquid material. SOLUTION: This container has at least two layers comprising a resin layer, such as a polypropylene layer, formed on the inner side brought into contact with a liquid crystal material such as a compound of the formula (R is a 1-5C alkyl; A is a single bond, trans-1,4-cyclohexylene; R is F, Cl, cyano, a 1-5C alkyl; ph is 1,4-phenylene) and a metal layer, such as an aluminum layer, formed on the outside of the resin layer. A liquid crystal is preferably stored in the container.

摘要： NEW MATERIAL:A compound shown by the formula I (R is cyano, 1-8C alkyl or alkoxy; is halogen; group shown by the formula II is trans-1,4-di-substituted cyclohexane ring). EXAMPLE:4-n-Pentylbenzoic acid trans-4'-(4''-chlorophenyl) cyclohexyl ester. USE:A liquid component for liquid crystal composition. A liquid crystal compound has a transition temperature from a high nematic phase to an anisotropic liquid phase, shows chemical stability, and liquid crystal display cell containing the compound shown by the formula I can display even at high temperature. Usable in a watch, electronic calculator, measuring equipment, etc. PREPARATION:A halobenzene is reacted with cyclohexene and acetyl chloride in the presence of AlCl3 to give a compound shown by the formula III, which is oxidized with an oxidizing agent such as m-perchlorobenzoic acid, etc. to give a compound shown by the formula IV, which is reduced with a reducing agent such as LiAlH4, etc. to give a compound shown by the formula V, and this compound is reacted with a 4-substituted benzoic acid chloride in the presence of a basic substance to give a compound shown by the formula I .

摘要： NEW MATERIAL:A liquid crystal compound of formulaI(R is 2W8C alkyl or alkenyl; R' is 2W8C alkyl or alkenyl).
EXAMPLE: 4'-n-Butyryloxyphenyl-trans-4-n-propylcyclohexanecarboxylate.
USE: A material for a liquid crystal display element having the following properties: (1) A wide nematic temperature range loated on a high temperature side. (2) No part for cutting off ultraviolet light is required since the compound is colorless, transparent and chemically stable. (3) Low viscosity and rapid response. (4) Slight change in threshold voltage with temperature and improved multiplex driving property.
PROCESS: A trans-4-alkylcyclohexanecarboxylic acid of formula II is reacted with thionyl chloride to give a compound of formula III, which is then reacted with an alkylcarbonyl chloride of formula IV to afford a compound of formula V. The resultant compound of formula V is then reacted with the compound of formula III in the presence of pyridine to give the compound of formulaI.

摘要： PURPOSE:To provide a liquid crystal compsn. which has high anisotropy in refractive index and is hardly brough into a smectic state, by incorporating a 4'-alkyl-(or alkoxy)-4-chlorobiphenyl. CONSTITUTION:For example, chlorobiphenyl of formula I and a compd. of formula II (wherein R is a 2-5C straight-chain alkyl) are subjected to a Friedel- Crafts acylation reaction in the presence of AlCl3 in dichloroethane to obtain an alkyl carboxylic acid chloride of formula III which is then mixed with hydrazine hydrate of the formula (NH2)2.H2O. The carbonyl group is then reduced in the presence of KOH in diethylene glycol to obtain a 4'-alkyl-(or alkoxy)-4-chlorobiphenyl of formula IV (wherein R is a 3-5C straight-chain alkyl or alkoxy). 1-50wt% 4'-alkyl-(or alkoxy)-4-chlorobiphenyl is added to a liquid crystal material.
