Abstract: A tetrahydrofuran-copolymer is obtained by co-polymerizing tetrahydrofuran with an alpha , omega -diol, in the presence of a heteropolyacid and a telogen. The telogen and/or diol are added in reactor (I) of the process. Water is distilled off directly from reactor (I), besides polymerization, throughout the reaction.

Abstract: Unsubstituted or alkyl-substituted THF is obtained by catalytic hydrogenation in the gas phase of C4-dicarboxylic acids and/or their derivatives using a catalyst comprising 20% by weight, preferably >30% by weight, in particular from 35 to 90% by weight, of an oxidic support having acid centers, at a hot spot temperature of from 240 to 310° C., preferably from 240 to 280° C., and a WHSV over the catalyst of from 0.01 to 1.0, preferably from 0.02 to 1, in particular from 0.05 to 0.5, kg of starting material/l of catalystxhour.

Abstract: Described is a process for the preparation of a particulate tetrahydro-3,5-dimethyl-1,3,5-thiadiazine-2-thione product by combining a first aqueous solution comprising methylammonium N-methyldithiocarbamate with a second aqueous solution comprising formaldehyde, followed by separation and drying of the resulting solid, which comprises combining the first and the second aqueous solutions in such a way that the ratio between the concentrations of dithiocarbamate functions and of formaldehyde is essentially constant in the reaction mixture over time during the duration of the reaction.

Abstract: The present invention relates to a process for preparing polytetrahydrofuran, polytetrahydrofuran copolymer, diester or monoester by polymerizing tetrahydrofuran in the presence of at least one telogen and/or comonomer and of an acidic heterogeneous catalyst based on activated sheet silicates or mixed metal oxides in a fluidized bed.

Abstract: A supported catalyst (I) containing 0.1-20 wt.% rhenium and 0.05-10 wt.% platinum (with respect to the total weight of the catalyst) is prepared by: (a) treatment of the optionally pretreated support with a solution of a rhenium compound; (b) drying and heating in a reducing atmosphere at 80-600 degreesC and; (c) impregnation with a solution of a platinum compound and drying. An Independent claim is also included for a process for the production of alcohols by catalytic hydrogenation of carbonyl compounds using the catalyst (I).
