The invention relates to a novel process for the preparation of ether and thioether compounds of formula ##STR1## by reacting compounds of formula ##STR2## with compounds of formula R.sub.1 --Y wherein R, R.sub.1, X, Y and n are as defined in claim 1, in the presence of an acid acceptor and in an aliphatic ketone, which process is carried out under pressure in the temperature range from 115.degree. to 200.degree. C.
本发明涉及一种新型的制备式为##STR1##的醚和
硫醚化合物的方法,其通过将式为##STR2##的化合物与式为R.sub.1 --Y的化合物在脂肪酮存在下,在酸受体存在下,在温度为115℃至200℃的范围内施加压力反应,其中R、R.sub.1、X、Y和n如权利要求1所定义。
