Abstract

L'invention concerne un procédé pour produire des éthers d'isopropényle de formule (A) dans laquelle R représente un groupe aliphatique, cyclo-aliphatique, aralyphatique, aromatique ou hétérocyclique pouvant porter d'autres substituants qui ne réagissent pas avec des acétylènes ou des allènes, ce procédé consistant à faire réagir un courant gazeux (I) qui contient la composante MAPD (méthylacétylène et/ou propadiène) et qui est obtenu dans un craqueur pour séparer des fractions C3, avec au moins un courant gazeux sélectionné entre un courant gazeux (II) qui contient un cétal d'acétone de formule (B) dans laquelle R a ladite signification, et un courant gazeux (III) qui contient un monohydroxyalcool de formule ROH dans laquelle R a ladite signification, en présence d'un catalyseur hétérogène.
