Abstract: The invention relates to a method for distillative separation of triethanolamin from a substance mixture consisting of mono- di-, and triethanolamin, ethanolamin-ether and water obtainable by an ammonia and ethylene oxide reaction in a liquid phase at a high pressure and temperature consisting in distilling the substance mixture in two stages. In the first stage, a low-boiling fraction and a high-boiling fraction are withdrawn and discharged, and in the second stage, a medium-boiling fractions is distilled at a triethanolamin content >99.4 % by weight and a diethanolamin content

Abstract: Process for separating triethanolamine continuously by distillation from a mixture of monoethanolamine, diethanolamine and triethanolamine together with ethanolamine ethers and water obtained by reaction of ammonia with ethylene oxide in the liquid phase under superatmospheric pressure and at elevated temperature, in which the mixture is distilled in two stages. The low-boiling fraction and the high-boiling fraction are taken off and discharged in the first stage and the intermediate-boiling fraction comprising >99.4% by weight of triethanolamine and

Abstract: Process for recovering cyclododecatriene (CDT) from a solution containing CDT and high boilers such as deactivated catalyst and polymers, which includes feeding the solution into a preheater and heating it, subsequently depressurizing it through a downstream pressure maintenance device and feeding the resulting two-phase mixture into a helical tube evaporator and there reducing the CDT content of the liquid phase by partial evaporation and discharging a gaseous product stream having an increased concentration of CDT.

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.
