Abstract
PURPOSE: To prepare the hydrogenated title compound in high yeild, suppressing the formation of by-products, without decomposing the polymer, by the hydrogenation of a solution of butadiene peroxide polymer in the presence of a specific amount of alkali and a hydrogenation catalyst.
CONSTITUTION: In the preparation of 1,4-butanediol by the hydrogenation of butadiene peroxide polymer in the presence of a hydrogenation catalyst, such as Raney-Ni, diatomaceous earth, alumina, etc., the solution of the perioxide polymer is mixed with the same volume of water, and further added with an alkali (pref. NaOH or KOH dissolved in water, alcohol, etc.) to attain a pH value of 6W9.
