Abstract: The invention relates to a method for processing at least partly deactivated polymerization catalysts for the polymerization or copolymerization of THF which are contaminated with the polymerization or copolymerization products of THF. The inventive method comprises the following steps: (a) purifying in a first step the polymerization catalyst by treating it with water vapor at a temperature of 80 to 250 DEG C and a pressure of 0.5 to 40 bar and preferably (b) regenerating the purified polymerization catalyst in a second step.

Date Jan. 18, 1996A process is disclosed for the selective hydrogenation of butynediol to 2-butene-1,4-diol using a palladium catalyst to which either copper and zinc, or silver and zinc, or copper, silver and zinc are added as doping agents. In the preferred embodiment, it has been possible, by optimizing the composition of the catalyst, to improve the activity and selectivity of the catalysts in question while also eliminating the need to handle toxic substances during the catalyst manufacturing process.

Abstract: A process for obtaining oligomers of polytetrahydrofuran or of tetrahydrofuran copolymers from a methanolic crude product which contains polytetrahydrofuran or tetrahydrofuran copolymers and is obtained in the transesterification of the mono- and/or diesters of polytetrahydrofuran or tetrahydrofuran copolymers with methanol, which includes a) removing the majority of the methanol from the crude product in a first distillation stage, b) separating the resulting bottom product by distillation into a top fraction containing the oligomers of polytetrahydrofuran or of tetrahydrofuran copolymers, and polytetrahydrofuran or tetrahydrofuran copolymer, and c) condensing the oligomers of polytetrahydrofuran or of tetrahydrofuran copolymers out of the top fraction from stage b).
