Abstract: The invention relates to a method for decoloring polymers or copolymers obtained by cationic polymerisation of tetrahydrofuran or tetrahydrofuran and alkylene oxide, optionally in the presence of a telogen, wherein a) the low boiling parts are initially separated by vacuum distillation or extraction and b) the remaining polymer or copolymer is heated to a temperature of 20-150 DEG C in the presence of at least one auxiliary agent selected from solid oxides and/or phyllosilicates.

Abstract: Polytetrahydrofuran, tetrahydrofuran copolymers, diesters or monoesters of these polymers are prepared by polymerizing tetrahydrofuran in the presence of at least one telogen and/or comonomer on a heterogeneous carrier catalyst which contains on an oxidic carrier material as active mass a catalytically active amount of at least one oxygenous molybdenum and/or tungsten compound and, when the precursor compounds of the active mass have been applied to the carrier material precursor, has been calcined at temperatures of between 500 DEG C and 1000 DEG C. The catalyst used contains a promotor which comprises at least one element or a compound of an element of the 2nd, 3rd including the lanthanides, 5th, 6th, 7th, 8th or 14th group of the periodic system of elements.

Abstract: The invention relates to a catalyst comprising alpha -aluminium oxide as the support material and copper as the active constituent, the BET surface (as defined in DIN 66131) of the aluminium oxide being not lower than 30 m /g. It also relates to a process for preparing said catalyst according to the invention, and the use thereof in dehydrogenation of cyclohexanol to form cyclohexanone, and also to the use of alpha -aluminium oxide, the BET surface (as defined in DIN 66131) of said aluminium oxide being not lower than 30 m /g, to prepare a catalyst.

Abstract: Cobalt catalysts (I) are claimed, in which the active material contains 55-98 wt% Co, 0.2-15 wt% P, 0.2-15 wt% Mn and 0.05-5 wt% alkali metal, calcd. as oxide. The calcined catalyst is reduced in a stream of hydrogen at final temps. of 200-400 deg C and then surface-oxidised in a stream of air at final temps. of 20-60 deg C. Also claimed is a process for the hydrogenation of organic nitriles and/or imines at 60-150 deg C and 50-300 bar using (I) as catalyst.
