Abstract
Unsaturated glycol diesters are prepared at high reaction rates, high degrees of conversion and high selectivity, by reacting a conjugated diene, a carboxylic acid and oxygen, in the presence of an improved active solid catalyst, in the liquid phase. The improved catalyst of the invention comprises palladium containing thorium as a promotor. In the preferred embodiment, butadiene and acetic acid are reacted with oxygen to produce the desired 1,4-diacetoxy-2-butene at high conversions and selectivity.
