CA 2556954

A carbonylation process for producing a carbonylation product by contacting carbon monoxide with a feed comprising an alcohol and/or a reactive derivative thereof in the vapour phase using an heterogeneous heteropolyacid catalyst comprising one or more metal cations selected from Cu, Fe, Ru, Os, Co, Rh, Ir, Ni, Pd and Pt and wherein there is at least 0.5wt% water present in the feed.

La présente invention a trait à un procédé pour la production d'un produit de carbonylation par la mise en contact de monoxyde de carbone avec une charge comportant un alcool et/ou un dérivé réactif de celui-ci dans la phase vapeur au moyen d'un catalyseur hétéropolyacide hétérogène comprenant une ou des cations métalliques choisis parmi Cu, Fe, Ru, Os, Co, Rh, Ir, Ni, Pd et Pt et dans lequel se trouve au moins 0,5 % en poids d'eau présente dans la charge.
