Abstract
A process is provided for hydrogenation of unsaturated diesters produced by the reaction of conjugated diolefin and monocarboxylic acid in which the diester is contacted with hydrogen in the presence of a noble metal and a monoamine. The presence of the monoamine suppresses hydrogenolysis of the diester to monoester. In a preferred embodiment 1,4-diacetoxy-2-butene is hydrogenated in the presence of a palladium catalyst and a monoamine selected from methylamine, n-butylamine, triethylamine, tripropylamine, quinoline, and toluidine.
