Abstract: The invention relates to a catalyst which contains a catalytically active quantity of at least one oxygen-containing molybdenum and/or wolfram compound on an oxidic support material and which has been calcinated at temperatures of 400 to 900° C. after the precursor compound of the catalytically active compounds have been applied to the support material or to a support material precursor. The transport pores for this catalyst each have a diameter of >25 nm and a volume of at least 50 mm /g. The catalyst contains x mumol (wolfram and/or molybdenum)/m molybdenum and/or wolfram, with 10.1 /g. Catalysts of this type are characterized by an acidity of at least 70 mumol/g at pKs

Abstract: The invention relates to a method for the single-step production of polytetrahydrofuran and/or tetrahydrofuran copolymers having an average molecular weight of 650 to 5000 daltons by polymerizing tetrahydrofuran on an acidic heterogeneous catalyst in the presence of at least one telogen and/or comonomer of the group of the alpha, omega diols, water, polytetrahydrofuran having a molecular weight of 200 to 700 daltons and/or of the cyclic ethers, characterized by a) removing the suspended and/or dissolved catalyst components and/or secondary products of the catalyst contained in the polymerization product, b) carrying out a separation in at least one distillation step from the resulting catalyst-free polymerization product to give a distillation product that contains the polymerization product and at least one tetrahydrofuran fraction, and returning at least part of the tetrahydrofuran fraction to the polymerization, and c) removing from the distillation residue of processing step b) the low-molecular polytetrahydrofuran and/or tetrahydrofuran copolymers that have an average molecular weight of 200 to 700 daltons, and obtaining a polytetrahydrofuran and/or tetrahydrofuran copolymer that has an average molecular weight of 650 to 5000 daltons.

Abstract: A process for obtaining oligomers of polytetrahydrofuran or of tetrahydrofuran copolymers from a methanolic crude product which contains polytetrahydrofuran or tetrahydrofuran copolymers and is obtained in the transesterification of the mono- and/or diesters of polytetrahydrofuran or tetrahydrofuran copolymers with methanol, which includes a) removing the majority of the methanol from the crude product in a first distillation stage, b) separating the resulting bottom product by distillation into a top fraction containing the oligomers of polytetrahydrofuran or of tetrahydrofuran copolymers, and polytetrahydrofuran or tetrahydrofuran copolymer, and c) condensing the oligomers of polytetrahydrofuran or of tetrahydrofuran copolymers out of the top fraction from stage b).
