A method for production of aryl alkyl ethers comprises reacting a hydroxyaromatic compound with an alcohol in the presence of a catalyst, whereby the homogeneous mixture of hydroxyaromatic compound, alcohol and catalyst is introduced into the reactor at normal pressure, reacted at a temperature of 250 to about 370 ~C and the product concentration in the reaction mixture adjusted such that the catalyst does not precipitate out.

L'invention concerne un procédé pour produire des éthers d'arylalkyle, ledit procédé consistant à faire réagir un composé hydroxy-aromatique avec un alcool en présence d'un catalyseur. Selon ce procédé, on introduit dans le réacteur un mélange homogène à la pression normale, contenant le composé hydroxy-aromatique, l'alcool et le catalyseur, puis on le fait réagir à une température comprise entre 250 ·C environ et 370 ·C environ, avant d'ajuster la concentration de produit dans le mélange réactionnel de façon à éviter la précipitation du catalyseur.
