Abstract
A process for producing octadienes comprises, on synthesis of octadienes by reacting butadiene with formic acid in the presence of a palladium catalyst, controlling the reaction pressure at not more than the vapor pressure of butadiene at the reaction temperature employed, thereby suppressing formation of byproducts which would accumulate in a catalyst-containing layer and minimizing the decrease of reaction rate and selectivity which would occur by such accumulation.
