    Abstract: This invention relates to modified Group IIIB metal-containing bimetallic or polymetallic catalysts and the use thereof in the preparation of alkoxylation products, i.e., condensation reaction products of alkylene oxides and organic compounds having at least one active hydrogen. In another aspect of this invention, processes are provided for preparing the modified Group IIIB metal-containing bimetallic or polymetallic catalysts for alkoxylation using a Group IIIB metal or a Group IIIB metal-containing compound as sources for the catalytically-active group IIIB metal. In a further aspect of this invention, processes are provided for preparing alkoxylation products that have beneficial, narrow molecular weight ranges using the modified Group IIIB metal-containing bimetallic or polymetallic catalysts.

    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.
