Abstract
Butadiene and water are reacted continuously in the presence of a solvent capable of dissolving both reactants and a palladium catalyst with the mole ratio of butadiene to the reaction product octa-2,7-dien-1-ol in the reaction mixture being maintained at 0.6 or more. By this process, octa-2,7-dien-1-ol can be produced continuously without reductions in reaction rate and selectivity and with decreased insoluble polymer formation.
