Process for selective ortho-methylation of cyclohexanones in the vapor phase

摘要

A cyclohexanone having at least one ortho-hydrogen is selectively methylated in the ortho-position in the vapor phase. High conversion of the selected cyclohexanone and high selectivity in the ortho-position are obtained. The reaction products include 2-methylcyclohexanone, 2,6-dimethylcyclohexanone and 2,6-xylenol.
