Abstract
Alkadienols are prepared by reacting a conjugated diolefin, such as butadiene, with water in the presence of palladium or platinum catalyst and in the presence of solvents. The addition of carbon dioxide to the reaction mixture greatly increases the yield of alkadienols. The products can be hydrogenated to saturated alcohols, useful for making plasticizers.
Claims29
Process for forming octadienols which comprises forming a reaction mixture containing butadiene, water, a solvent which is at least partially miscible with water and butadiene and carbon dioxide and a catalyst which is a palladium compound complexed with a phosphine ligand, causing the butadiene and water to react at a reaction temperature of from 20.degree.C. to 180.degree.C;
- to form an octadienol and recovering the octadienol from the reaction mixture;
- said butadiene, carbon dioxide and water being present in amounts sufficient to produce said octadienol.
