Abstract

Vinyl esters of aliphatic monocarboxylic acids having less than five carbon atoms are reacted with alcohols having the formula R1R2CHOH, in which R1 is halogenmethyl, cyano, cyanomethyl or aldomethyl and R2 is alkyl or the same as R1 in the presence of a reaction medium containing sufficient alkali-metal salt or tertiary amine to give a pH greater than 7.0. Examples of such secondary alcohols are: methyllactate, aldol, glycerol, diacetin, aldolcyanhydrin, lactonitrile and glycerol-a -d -dichlorhydrin and suitable catalysts are cyanides, silicates, carbonates and tetraborates of alkali metals, triethylamine and tributylamine. In examples: (1) vinyl acetate is reacted with aldol, lactonitrile, diacetin and glycerol-a : d -dichlorhydrin; (2) vinylformate is reacted with lactonitrile; (3) vinylpropionate is reacted with lactonitrile; (4) methyllactate containing some potassium cyanide is circulated through a reservoir, a stainless steel coil immersed in a cooling bath and back to the reservoir while vinylacetate is slowly introduced. The resulting ester of the secondary alcohol is usually recovered by distillation, the acetaldehyde simultaneously produced may be separated, however, by reacting with a compound which yields a product capable of removal by filtration or decantation.
