Process for producing alkadienols
 The disclosure describes a process for producing alkadienols comprising the steps of: reacting a conjugated alkadiene with water in a reaction solvent in the presence of a palladium catalyst; distilling the obtained reaction mixture so as to separate the reaction solvent from the reaction mixture while directly supplying heated water, steam or a mixture thereof as a heating medium to a distillation column, under the condition that the temperature of a bottom liquid in the distillation column is not higher than 120.degree. C.; and phase-separating bottoms discharged from the bottom of the distillation column.
