The present invention provides a method for synthesizing 4,4'-dihydroxybiphenyl. By using biphenyl as a starting material, 4,4'-dicyclopentylbiphenyl or 4,4' is obtained through Friedel-Crafts alkylation reaction. -Dicyclohexylbiphenyl, and then through the oxidation reaction to obtain hydroperoxide and then cracking reaction, the target product 4,4'-dihydroxybiphenyl can be obtained. The entire synthesis process has high selectivity, high yield and convenient operation. And green and environmental protection, suitable for industrial production. |
