NEW MATERIAL:A 4-trans(trans-4'-alkylcyclohexyl)cyclohexylmethyl 4-cyanophenyl ether of formulaI(R is 1W10C alkyl). n USE: A high-temperature liquid crystal component capable of increasing the clear point of a liquid crystal mixture by mixing with one or several types of a Schiff base liquid crystal, azoxy liquid crystal, biphenyl liquid crystal, etc. n PROCESS: A compound of formula II is reacted with a halogenating agent to give a compound of formula III, which is then reacted with ethanol to afford a compound of formula IV. The resultant compound of formula IV is then reduced with LiAlH 4 in a solvent, e.g. THF, at a low temperature to give a compound of formula V, which is then reacted with hydrobromic acid under acidic conditions with sulfuric acid to afford a compound of formula VI. The resultant compound of formula VI is reacted with a compound of formula VII to afford the compound of formulaI. n COPYRIGHT: (C)1982,JPO&Japio |
