Method for synthesizing carvacrol from dipentene dioxide

The invention discloses a method for synthesizing carvacrol from dipentene dioxide. The method comprises the following steps: step 1, utilizing the dipentene dioxide as a raw material and performing reducing reaction in a solvent A through the action of ammonium formate to obtain alpha,alpha,6-trimethyl-7-oxa bicyclo(4.1.0)heptane-3-methyl alcohol under the situations of hydrogen pressurization and utilizing Pd/C as a catalyst; step 2, performing dehydrating and rearranging reaction on the alpha,alpha,6-trimethyl-7-oxa bicyclo(4.1.0)heptane-3-methyl alcohol obtained in step 1 under acid catalysis to obtain iso-dihydrocarvone; step 3, dissolving the iso-dihydrocarvone obtained in step 2 and a carbon-based compound catalyst into a solvent and heating the mixture to generate dehydrogenation oxidation reaction, generating carvacrol, filtering the carvacrol to separate the carbon-based compound catalyst and performing reduced pressure rectification on filtrate to obtain a carvacrol finishedproduct. The Pd/C, the a
