Abstract

Polycarboxylic acids, esters and nitriles, e.g. adipic acid, dimethyl adipate and adiponitrile are prepared by reacting an acetylenically unsaturated compound with an organic carboxylic acid, anhydride, ester, salt, or nitrile thereof in the presence of a free-radical initiator as catalyst. Acetylene or substituted acetylenes may be used and the free-radical initiator may be a peroxide, or an organic or inorganic persalt. A large excess of the acid component may form the reaction medium, or an inert diluent may be present. Examples describe the preparation of adipic acid, 2,5-dimethyladipic acid, 4-carboxymethyloctanedioi acid, disodium adipate, dimethyl adipate and adiponitrile.
