Method for continuously producing alkadienols
 A method for continuously producing alkadienols, which comprises subjecting a conjugated alkadiene and water to a hydration dimerization reaction in a continuous type reactor in the presence of carbon dioxide and a catalyst comprising a palladium compound and a phosphorus compound, wherein a hydrophobic phosphorus compound is used as the phosphorus compound, and the reaction is carried out in the presence of an amine while maintaining the concentration of the conjugated alkadiene in the reaction solution in the reactor within a range of from 0.5 to 4.5 wt %.
