ABSTRACT:
The present invention provides an improved process for the production of ortho-alkyl phenols by vapor phase reaction of a phenol having at least one ortho-hydrogen with an alcohol, the improvement comprises soaking manganic oxide in an aqueous solution of alkali metal salt, separating the soaked manganic oxide from the solution, drying and calcining the soaked manganic oxide at a temperature of 300.degree.-600.degree. C. for a period of 1-3 hours to form an alkali metal oxide thereon, wherein the weight ratio of the alkali metal oxide to the manganic oxide is 0.5-0.0001 wt %, preferably 0.1-0.001 wt %.
