Abstract
A process for producing a conjugated diene monoester by reacting a gaseous mixture comprising a conjugated diene, a carboxylic acid and oxygen as reactive components, in which the fraction of said conjugated diene is preferably 12-60 mole % and the fraction of oxygen is preferably 5-30 mole %, in the gas phase in the presence of a catalyst, characterized by carrying out the reaction in the presence of a catalyst which comprises, as active components, (a) palladium, (b) at least one member selected from the group consisting of magnesium, calcium, barium, cerium, lanthanum, tungsten, copper, zinc, cadmium, boron, thallium, molybdenum, tin, lead, phosphorous, arsenic and selenium and (c) at least one alkali metal carboxylate, or a catalyst which comprises, as active components, these three components (a), (b) and (c) together with (d) at least one alkali metal halide.
