Abstract: Acrylic acid compounds of the general formula CHR1=CR2-COX in which R1 is hydrogen or a methyl group, R2 is hydrogen or a methyl group, X is an alcohol, mercaptan or secondary amine radical attached through the hetero atom, are produced by heating at between 60 DEG and 500 DEG C. an ethylenedicarboxylic acid derivative of formula with a tertiary phosphine, tertiary arsine or tertiary stibine as catalyst. When carried out in the liquid phase, the temperature is preferably between 80 DEG and 260 DEG C. A metal, metal oxide, metal hydroxide, metal sulphide, or metal salt may be used as activator. A tertiary phosphine may be used in admixture with one or more of a tertiary arsine or stibine, the mole ratio of phosphine to the other tertiary component or components being between 1 : 0,1 and 1 : 0,5. The catalyst may be applied to a porous support. A nonreactive gas may be introduced into the reaction mixture during the reaction to carry off the products formed. Alternatively, the initial material may be dissolved in a low-boiling solvent prior to its addition to the catalyst. Numerous examples of initial materials, catalysts, and activators are given.
