Abstract: NCO compounds with covalently bonded polyhedral oligomeric silicon-oxygen cluster units and good solubility are suitable as crosslinkers in coating systems. The NCO compounds lead to improved coating properties, such as good leveling of cured baking varnishes.

Abstract: The invention relates to a process for preparing functionalized oligomeric silsesquioxanes by reacting incompletely condensed oligomeric silsesquioxanes with alkoxysilanes and also to their use for further derivatizations, for the synthesis of catalysts and their starting compounds, and for the synthesis and modification of polymers.

Abstract: A radiation-curable powder coating composition, contains: I. a binder containing at least one compound crosslinkable by actinic radiation; and II. at least one compound containing polyhedral oligomeric silicon-oxygen cluster units, represented by the formula [(RaXbSiO1.5)m(RcXdSiO)n(ReXfSi2O2.

Abstract: The invention relates to a method for catalytically oxidizing unsaturated hydrocarbons to form oxidation products, and to the production of saturated alcohols, ketones, aldehydes or carboxylic acids by subsequently hydrogenating the oxidation product. A compound of formula (I) is used as a catalyst during oxidizing in which: R1, R2═H, an aliphatic or aromatic alkoxy radical, carboxyl radical, alkoxycarbonyl radical or hydrocarbon radical, each having 1 to 20 carbon atoms, SO3H, NH2, OH, F, Cl, Br, I and/or NO2, whereby R1 and R2 signify identical or different radicals or R1 and R2 can be coupled to one another via a covalent bond, with Q1, Q2=the same or different, C, CH, N; X, Z═C, S or CH2; Y═O or OH; k=0, 1 or 2; 1=0, 1 or 2; m=1 to 100 in the presence of a radical initiator. Peroxy compounds or azo compounds can be used as radical initiators. Preferred substrates are cyclic aliphatic or aromatic compounds.

Abstract: The invention relates to a process for manufacturing zeolite catalysts containing subgroup metals by hydrothermal synthesis with subsequent calcination, which is characterized in that the subgroup metals are used in hydrothermal synthesis in the form of carbonyl, isonitrile or cyanocomplexes.

Abstract: The invention relates to a method for oxidizing substrates such as hydrocarbons, waxes or soot. The method involves the use of a compound of formula (I) in which: R1 and R2 represent H, an aliphatic or aromatic alkoxy radical, carboxyl radical, alkoxycarbonyl radical or hydrocarbon radical, each having 1 to 20 hydrocarbon atoms, SO3H, NH2, OH, F, Cl, Br, I and/or NO2, whereby R1 and R2 designate identical or different radicals or R1 and R2 can be linked to one another via a covalent bonding; Q1 and Q2 represent C, CH, N, CR5, each being the same or different; X and Z represent C, S, CH2, each being the same or different; Y represents O and OH; k=0, 1, 2; l=0, 1, 2; m=1 to 3, and; R5 represents one of the meanings of R1. Said compound is used as a catalyst in the presence of a radical initiator, whereby the molar ratio of the catalyst to the hydrocarbon is less than 10 mol %. Peroxy compounds or azo compounds can be used as the radical initiator.
