A process is disclosed for producing a 3-pentenoic ester which comprises reacting butadiene, carbon monoxide and an alcohol in the presence of cobalt carbonyl catalyst, characterized in that the reaction is carried out in a reaction medium composed of at least two solvents selected from the group consisting of pyridine, quinoline, isoquinoline and substituted pyridine, substituted quinoline and substituted isoquinoline in which substituent or substituents are selected from the group consisting of alkyl having 1-6 carbon atoms, alkenyl having 1-6 carbon atoms, aryl, alkylaryl having 7-10 carbon atoms and aralkyl having 7-10 carbon atoms.

Process for producing 3-pentenoic esters

Ethanol is produced with a good selectivity and good conversion from methanol, carbon monoxide and hydrogen by conducting reaction in the presence of a cobalt sulfide or a mixture of a cobalt sulfide and at least one of a nitrogen-containing compound and a phosphorus compound.
