Abstract
A process and novel catalyst for the carbonylation of one or more of alcohols, ethers and ether alcohols to esters and, optionally, to carboxylic acids. The reaction is effected in the vapor state over a solid catalyst comprising a polyoxometalate anion in which the metal is at least one taken from Group V and VI of the Periodic Chart of the Elements complexed with a cation from a member of Group VIIIA of the Periodic Chart of the Elements. Preferably, the catalyst is deposited on a support that is inert to the reaction. The preferred support is silica.
Claims14
A process for the carbonylation of one or more alcohols, ethers and ether alcohols to esters and, optionally, to carboxylic acids, by reaction thereof in the vapor state over a solid catalyst comprising a polyoxometalate anion in which the metal is one or more metals selected from the group consisting of molybdenum, tungsten, vanadium, niobium, chromium, and tantalum, complexed with a cation of one or more metals selected from the group consisting of Fe, Ru, Os, Co, Rh, Ir, Ni, Pd and Pt.
