process for the production of 2 - methyl - 1 - and 2 - cyclohexandion methylresorcinol.

摘要

A process for producing 2-methyl-1,3-cyclohexanedione which comprises subjecting 1,3-cyclohexanedione, formaldehyde and a dialkylamine to Mannich reaction to obtain a 2-dialkylaminomethyl-1,3-cyclohexanedione, and subjecting the 2-dialkylaminomethyl to hydrogenolysis, and a process for producing 2-methylresorcinol which comprises aromatizing 2-methyl-1,3-cyclohexanedione obtained. According to these processes, it is possible to produce high-purity 2-methylresorcinol and 2-methyl-1,3-cyclohexanedione commercially easily and advantageously.
