synthetic route
Methyl cyclohexane can be prepared by the following main methods:
Fischer esterification method with cyclohexane carboxylic acid and methanol acid catalysis (such as H2SO4), reflux ≈ 99%
The reaction between methyl formate and cyclohexene addition in the presence of cyclohexene+methyl formate catalyst is approximately 48%
3-Chlorocyclohexane two-step method: Chlorocyclohexane → hydrolysis → esterification hydrolysis to obtain cyclohexanol, followed by oxidation esterification with a total yield of 65%
Note: Fischer esterification method is a mainstream process in laboratory and industry, with simple operation and high yield.
