Abstract:
A process for preparing 2,6-dimethylphenol from a 2,4,6-trimethylphenol solution, comprising steps of:effecting a selective oxidation of said 2,4,6-trimethylphenol solution by reacting with an oxygen-containing gas to produce a 3,5-dimethyl-4-hydroxybenzaldehyde at temperatures of 20 to 200Â° C. in the presence of an iron-containing catalyst system and a first solvent; and effecting a deformylation of said 3,5-dimethyl-4-hydroxybenzaldehyde to produce said 2,6-dimethylphenol at temperatures of 50 to 400Â° C. in the presence of a copper-containing catalyst system and a second solvent.
