PROCESS FOR PRODUCING ALKADIENOL

摘要

A process for producing an alkadienol which comprises reacting a conjugated alkadiene with water in a reaction solvent in the presence of a palladium catalyst, separating the solvent from the resultant reaction mixture by distilling the mixture under the condition wherein the temperature of the bottom oil in a distillation column is 120 C or below while directly feeding hot water and/or steam as the heat-transfer medium to the column, and subjecting the bottom to phase separation. This process causes neither the decomposition and/or polymerization of the formed alkadienol nor the metallation of the palladium catalyst, and hence serves to inhibit the loss of the alkadienol and the catalyst and provide the objective alkadienol in a high yield.
