Abstract

PURPOSE: A catalyst containing iron oxide and alumina at a specific ratio is used to effect the reaction of a phenol bearing a hydrogen on the ortho position with an alcohol, thus producing a phenol alkylated on the ortho position in high conversion and selectivity.
CONSTITUTION: When a phenol bearing a hydrogen atom on the ortho position is alkylated with an alcohol, a catalyst that contains iron, aluminum and oxygen as essential components where the atomic ratio of iron to aluminum is 100/(0.1W20), preferably 100/(0.5W10) is used. The above mixture catalyst is prepared by coprecipitation from an iron salt and an aluminum salt or alumina sol with an alkali, drying and calcination or by mixing an iron salt and an aluminum salt, drying, decomposing and calcining them. During the reaction, the admixing of steam to the reaction system at a molar ratio of (1W10) (steam)/1 (phenol) increase the recovery yield of the remaining alcohol and prevents the reduction in catalyst activity.
