    摘要: Unsaturated glycol diesters are prepared in an extremely high degree of conversion and selectivity by reacting a conjugated diene, a carboxylic acid and oxygen in the presence of a solid, active, long-lived catalyst composed of a mixture of palladium and at least one component of antimony, bismuth, selenium or tellurium supported on activated carbon, which catalyst is prepared by subjecting the mixture to reduction, treating the mixture with oxygen or an oxygen-containing gas at an elevated temperature and subjecting the treated mixture to reduction again.
