Title (EN) VAPOR-PHASE CARBONYLATION OF LOWER ALIPHATIC ALCOHOLS USING TIN PROMOTED IRIDIUM CATALYST
(FR) CARBONYLATION EN PHASE VAPEUR D'ALCOOLS ALKYLIQUES INFERIEURS UTILISANT UN CATALYSEUR D'IRIDIUM ACTIVE A L'ETAIN
Abstract: front page image
(EN)A vapor-phase carbonylation method for producing esters and carboxylic acids from reactants comprising lower alkyl alcohols, lower alkyl alcohol generating compounds, and mixtures thereof. The method includes contacting the reactants and carbon monoxide in a ccarbonylation zone of a carbonylation reactor under vapor-phase conditions with a catalyst having a catalytically effective amount of iridium and tin associated with a solide carrier material.
(FR)L'invention porte sur un procédé de carbonylation en phase vapeur permettant d'obtenir des esters et acides carboxyliques utilisant des réactifs comprenant des alcools inférieurs, des alcools alkyliques inférieurs, des composés générateurs d'alcools alkyliques inférieurs et leurs mélanges. Le procédé consiste à mettre en contact les réactifs et du CO dans la zone de carbonylation du réacteur de carbonylation dans des conditions de carbonylation en phase vapeur avec un catalyseur contenant des quantités à effet catalytique d'iridium et d'étain associés à un support solide.
