The present invention concerns a process for the etherification of olefins. According to the process, an olefin or a mixture of olefins is reacted with an alcohol or a mixture of alcohols in the presence of a catalyst. According to the invention, a catalyst is used which comprises a grafted polymer fiber, there being functional groups attached to the grafted polymer fiber. By means of the invention it is possible to speed up the etherification process of in particular heavier ethers.

Cette invention a trait à un procédé d'éthérification d'oléfines. Dans le cadre de ce procédé, on fait réagir une oléfine ou un mélange d'oléfines avec un alcool ou un mélange d'alcools en présence d'un catalyseur. Ce catalyseur comprend une fibre de polymère greffé auquel sont attachés des groupes fonctionnels. La mise en oeuvre de ce procédé permet d'accélérer le processus d'éthérification, notamment d'éthers plus lourds.
