Metal carboxylate-alkoxy alcoholate composition and process

Abstract

Metal carboxylate-glycol or carboxylate-glycol ether compositions, useful as siccatives in paint and like coating drier compositions, as internal combustion engine fuel--and other fuel--additives, and as stabilizers for polyvinyl chloride type plastics, and soluble in linseed oil and in aliphatic and aromatic hydrocarbon solvents, are prepared in liquid form by heating a mixture of (a) an appropriate metal powder or compound such as an oxide, hydroxide, acetate, or carbonate, (b) a branched chain aliphatic or a non-aromatic cyclic carboxylic acid, even an acid as low as a five carbon acid, or a mixture of such acids, and (c) a polyol or an alkoxy alkanol, e.g., a glycol or glycol ether; and, after filtration of the reaction mix, distilling off any volatile reaction by-product and also excess glycol or glycol ether. Higher than the usual equivalents of metal may be reacted for each equivalent of acid used. Certain of the products have remarkably low viscosity without special dilution. The products are believed to be metal carboxlate-glycolate, -ether glycolate-alcoholate complexes.
