Paragraph 0066; 0070; 0076, (2019/04/10)
The invention discloses a preparation method of trans-trans dicyclohexyl alkane liquid crystal compounds. According to the preparation method, 1-(4-(4-alkylcyclohexyl)phenyl)alkyl-1-one is used as a raw material; a benzene ring is converted into a cyclohexyl ring by means of a catalytic hydrogenation reaction; transposition is performed under the alkaline condition, so that 1-(4-(4-alkylcyclohexyl)cyclohexyl)alkyl-1-ol is obtained; the trans-trans dicyclohexyl alkane liquid crystal compounds are finally obtained by carrying out an oxidation reaction and a reduction reaction. The preparation method provided by the invention is unique in synthetic route, not only realizes green chemical industry, but also enables the product yield to be greatly increased, improves the product quality, and reduces the cost.
