Patent

CA 2394030

The present invention relates to processes for making a reaction product comprising trimethylpentene(s) which com-prises contacting C4 olefinic feedstock containing isobutene and n- butene(s) with a catalyst comprising zeolite beta under conditions allowing selective dimerization of isobutene to trimethylpentene(s). It also relates to the products obtained by these processes.

La présente invention concerne des procédés d'obtention d'un produit réactionnel comprenant au moins un triméthylpentène, qui consistent à mettre en contact une matière de départ oléfinique contenant de l'isobutène et au moins un n-butène avec un catalyseur comprenant de la zéolite bêta, dans des conditions permettant la dimérisation sélective de l'isobutène en triméthylpentène(s). L'invention concerne également les produits obtenus selon ces procédés.
