Procédé de O-alkylation des composés phénoliques.

摘要

Process for O-alkylation of phenolic compounds, more particularly a process for the preparation of the ethers derived from diphenols. The characteristic of the process consists in reacting the said phenolic compound with an alkanol, in gas phase, in the presence of an effective quantity of a catalyst chosen from orthophosphates of trivalent rare-earth metals.
