Process for the synthesis of aryl alkyl monoethers |
摘要 |
The invention relates to a process for the synthesis of aryl alkyl monoethers by reaction of a phenol compound, comprising one or more hydroxyl groups attached to the aromatic system, and of a dialkyl carbonate. It is a solvent-free process carried out at a pressure of between 0.93x105 Pa and 1.07x105 Pa, at a temperature of between 100° C. and 200° C., and in the presence of a catalyst chosen from the group consisting of alkaline carbonates and alkaline hydroxides. The dialkyl carbonate is added gradually to the reaction mixture.
