Abstract: Process for regenerating spent multimetal oxide oxidation catalysts from catalytic gas-phase oxidations of lower organic compounds, which catalysts, unspent, contain as base constituents the elements Mo, W, V and Cu in oxide form, by the action of oxidising agents and of solubilising aqueous ammonia containing added acetic acid and/or the ammonium salt thereof and subsequent drying and calcination in which, within the process, the content of the metallic constituents is quantitatively determined and supplemented to the respective original value.

Abstract: Polytetrahydrofuran, polytetrahydrofuran copolymers, diesters or monoesters of these polymers are prepared by polymerization of tetrahydrofuran in the presence of at least one telogen and/or comonomer, which is in the form of shaped catalyst bodies or catalyst particles having a volume of the individual shape of the body or particle of at least 0.05 mm 3 , preferably at least 0.2 mm 3 , in particular 1 mm 3 , and has at least one of the features a) and b): a) a pore radius distribution having at least one maximum in the pore radius range from 100 to 5000 Å, b) a pore volume of catalyst pores having radii of 200-3000 Å of greater than 0.05 cm 3 /g and/or a pore volume of pores having radii of 200-5000 Å of greater than 0.075 cm 3 /g and/or a pore volume of pores having radii of >200 Å of greater than 0.1 cm 3 /g.

Abstract: A solvent-free curable composition has a long shelf life and consists of A 100 parts by weight of an epoxy resin and B from 10 to 100 parts by weight of, as a curing agent for the epoxy resin, an aromatic diamine containing groups, with or without C from 0.01 to 5 parts by weight of an accelerator, the curing agent for the epoxy resin being finely dispersed in the latter and preferably having a particle size of less than 10 mu m. The preferred epoxy resin curing agent is 4,4'-diaminodiphenyl ketone. The curable composition is used in particular for the preparation of fiber-reinforced materials.
