Abstract: A method for the regeneration of deactivated polymerization catalysts based on layered silicates involves (a) reducing the content of oxidizable organic impurities from the polymerization reaction by extraction with a solvent in the liquid or vapor state and then (b) calcining in an oxygen-containing atmosphere at 400-600 deg C.

Abstract: Procedimiento para la obtención de politetrahidrofurano, copolímeros de tetrahidrofurano, sus mono- o diésteres, así como los mono- o diésteres de politetrahidrofurano con índices de color reducidos en presencia de un catalizador, en el que el tetrahidrofurano crudo obtenido de modo conocido en sí se transforma en tetrahidrofurano puro por destilación, a continuación éste se somete a un hidrogenado sensiblemente completo en un catalizador que presenta metales de transición de los grupos 7 a 10 del Sistema Periódico de los Elementos, o sus óxidos, sobre un soporte, que es seleccionado a partir de óxido de aluminio, óxido de silicio, piedra pómez, bentonita, silicato de magnesio o mezclas, y el tetrahidrofurano altamente puro obtenido de este modo se emplea para la polimerización inmediatamente después de su obtención.

Abstract: The invention provides a process for preparing polytetrahydrofuran, tetrahydrofuran copolymers, their monoesters or diesters and the monoesters or diesters of polytetrahydrofuran having a low color number in the presence of a catalyst, which comprises converting crude tetrahydrofuran which has been prepared in a manner per se into pure tetrahydrofuran by distillation, subsequently subjecting the latter to essentially complete hydrogenation and using the high-purity tetrahydrofuran obtained in this way for the polymerization directly after its preparation.

Abstract: The invention relates to a method for the production of polytetrahydrofuran, tetrahydrofuran copolymers, diesters or monoesters of the above polymers with low colour index. The invention is characterised in that the polymer, obtained by cationic polymerisation of tetrahydrofuran is hydrogenated in the presence of a macroporous, supported, heterogeneous catalyst, the active metal of which is at least one metal of the VII to X transition group of the periodic table.

Abstract: PCT No. PCT/EP95/02592 Sec. 371 Date Mar. 20, 1997 Sec. 102(e) Date Mar. 20, 1997 PCT Filed Jul. 4, 1995 PCT Pub. No. WO96/01242 PCT Pub. 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.
