Abstract
An aluminum and phosphorus mixed oxide catalyst is prepared by coprecipitating an aluminum and phosphorus mixed compound from a solution of water-soluble aluminum and phosphorus compounds; drying the precipitate at 80-180 degreesC; and calcining in air stream the dried precipitate by gradual heating from room temperature to 400-800 degreesC. Independent claims are also included for: (1) an aluminum (Al) and phosphorus (P) mixed oxide catalyst having an Al:P atomic ratio of 0.4:1-1:1 and surface area of 40-100 m2/g; and (2) a process for the preparation of polyhydroxybenzenes monoalkylethers optionally having alkyl or halogen on the aromatic ring, by reaction with optionally substituted 1-6C alcohols, in gas, liquid or mixed phase being catalyzed by the inventive catalyst.
