Preparation method of 3, 4-epoxycyclohexyl formate-3'4'-epoxycyclohexyl methyl ester

The invention discloses a method for synthesizing 3, 4-epoxycyclohexycarboxylic acid-3'4'-epoxycyclohexyl methyl ester under the solvent-free triphase-transfer catalysis. In the method, oxyful and 3-cyclohexenecarboxylic acid-3'-cyclohexene methyl ester (CAS:2611-00-9) are used as raw materials, polymer material chloromethylation styrene resin and polyvinyl chloride resin are used as carriers, grafting quaternary ammonium salt is used as triphase-transfer catalyst, and no organic solvent is present. Under the circumstance of normal pressure and a temperature of 30-80 DEG C, the reaction lasts 1-6 hours, and then the target product, 3,4-epoxycyclohexycarboxylic acid-3'4'-epoxycyclohexyl methyl ester, is obtained. Compared with existing methods, the invention has easier access to the raw materials and has the advantages of low production cost, mild reaction condition, simple and convenient product separation after the reaction, and remarkable energy conservation and consumption reduction. The triphase-transfer
