    Abstract: Disclosed is a 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.

    Abstract: A colorant composition for use in coating compositions is disclosed. The colorant composition comprises a pigment component, for imparting a color to the coating composition, and a liquid vehicle for the pigment component. At least a portion of the liquid vehicle is a nitrogen-containing component selected from compounds which have a formula

    and mixtures thereof, wherein each R is independently selected from the group consisting of H, monovalent hydrocarbyl radicals having 1 to about 4 carbon atoms, divalent hydrocarbyl radicals having 1 to about 2 carbon atoms,and R'OH wherein R' is a divalent hydrocarbyl radical having 1 to about 4 carbon atoms, provided that the compound includes at least one hydroxyl group and if one R is a divalent radical then another R is a bond in the divalent radical or is another divalent radical. The use of such nitrogen-containing components provides colorant compositions having substantial benefits, e.g., substantially similar or better performance characteristics and reduced toxicity relative to current colorant compositions.
