Claim Text:
1. A method for producing 2,7-octadien-1-ol, comprising: subjecting butadiene and water to a telomerization in the presence of a palladium catalyst, a tertiary amine and carbon dioxide, the palladium catalyst comprising a water-soluble triarylphosphine and a palladium compound, the water-soluble triarylphosphine comprising two or more sulfonate groups; mixing a telomerization solution obtained by the telomerization with an organic solvent having a dielectric constant of 2 to 18 at 25° C. to form a liquid having an aqueous phase and an organic phase; and carrying out phase separation of the liquid in the presence of carbon dioxide by recovering the 2,7-octadien-1-ol from the organic phase while retaining the palladium catalyst in the aqueous phase.
