Phosphorous-aluminium-mixed oxide catalyst, process for its preparation and use thereof.

摘要

An A1 and P mixed oxide, with surface area 50-100 m<2>/g, prepared by gradually heating up to 400-800 DEG C a mixed compound in its turn obtained by coprecipitation from an aqueous solution of A1 and P compounds, is advantageously used as a catalyst for the monoalkylation of diphenol compounds.
