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: Process for the production of at least one alkanolamine by reaction of ammonia with alkylene oxide. The process is carried out in a reactor in the presence of a catalyst and yields mono-, di and/or trialkanolamines. The distribution of the different alkanolamines is regulated by the temperature in the reactor, which is characterized by adjustment of the temperature by regulation of the temperature profile in the reactor.

Abstract: Process for preparing an ethylamine by reacting ethanol with ammonia, a primary amine or a secondary amine in the presence of hydrogen and a heterogeneous catalyst, in which a biochemically prepared ethanol (bioethanol) in which the concentration of sulfur and/or sulfur-containing compounds has been reduced beforehand by bringing it into contact with an adsorbent is used.

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.
