Abstract: PROBLEM TO BE SOLVED: To provide a process for removing the sodium once more which derives from a catalyst after transesterification with minimum facilities. SOLUTION: For producing a hydroxyl group-containing polymer, especially a polytetrahydrofuran containing a hydroxyl end group, a corresponding acyloxy group-containing polymer, used as a start material, is transesterified with an alcohol in the presence of a sodium-containing catalyst, and for removing sodium cations, following the transesterification, in a catalytic amount of water, the polytetrahydrofuran solution is directly introduced into at least one ion exchanger and allowed to flow through it.

Abstract: PROBLEM TO BE SOLVED: To provide a method which effects the subject reaction in the vapor phase advantageously from industrial, economical and environmental aspects in the presence of a catalyst composed of copper and Na2 O supported by a carrier composed of SiO2 and CaO. SOLUTION: This method effects the subject reaction in the presence of free hydrogen by passing 1,4-butanediol over an immobilized phase of catalyst composed of 4 to 40wt.%, preferably 4 to 32wt.%, of copper and 0 to 5wt.%, preferably 0 to 2wt.%, of Na2 O, each percentage being based on the total quantity of the catalyst, supported by a carrier composed of 80 to 100wt.%, preferably 90 to 100wt.%, of SiO2 and 0 to 20wt.%, preferably 0 to 10wt.%, of CaO, where the copper grains having an average diameter of 10 to 100nm are dispersed at a rate of 20 to 50% so as to have a surface area of 10 to 50m /g over the carrier, under the conditions of temperature: 150 to 300 deg.C, preferably 190 to 230 deg.C, absolute pressure: 1 to 40 bar, preferably about 1 bar, and hourly space velocity of 1,4-butanediol: 0.2 to 20kg, preferably 0.5 to 7.5kg, per kg copper, with the carrier gas containing free hydrogen being reused as the recycle gas.
