| titleOfInvention | Process for the carbonation of diolefins |
| abstract | Conjugated diolefins (e.g., 1, 3-butadiene) are carbonylated by the palladium-catalyzed addition of carbon monoxide and an alcohol of the formula ROH (e, g., benzyl alcohol) whereby polycarboxylic esters are formed in which the pair of double bonds of the conjugated diolefin has been transformed into a moiety having the formula: (FORMULA) In the process, the olefin, carbon monoxide, and alcohol are reacted in the presence of a palladium (II) salt a copper (II) salt and a base, at certain concentrations and at a pressure and temperature sufficient to effect the carbonylation. The resulting unsaturated diester can be hydrolyzed and hydrogenated or vice versa to obtain the corresponding linear diacid (e.g., adipic acid). |
