标题 :Synthesis of nanoparticles

权利人:CT ANGEWANDTE NANOTECH CAN
摘要:Methods for the preparation of inorganic nanoparticles capable of fluorescence, wherein the nanoparticles consist of a host material that comprises at least one dopant. The synthesis of the invention in organic solvents allows to gain a considerably higher yield compared to the prior art synthesis in water. All kinds of objects can advantageously be marked and reliably authenticated by using an automated method on the basis of a characteristic emission. Further, the size distribution of the prepared nanoparticles is nartower which renders a subsequent size-selected separation process superfluous.

标题:Process for the enatioselective synthesis of intermediates used

权利人:HOECHST MARION ROUSSEL INC
摘要:A process for the stereoselective synthesis of [R]- and [S]-2,3-dihydro-1,3-dimethyl-2-oxo-1H-indole-3-acetonitriles comprises reacting racemic and 5-alkoxy-substituted (+/-)-1,3-dimethyloxindoles with a halogenated acetonitrile in the presence of a substituted N-benzyl cinchoninium, quinidinium, cinchonidinium, or quininium catalyst. The resulting alkylated oxindoles can be converted to primary amines by catalytic reduction in the presence of hydrogen gas. One of the primary amines, such as enantiomers of 3-(2-aminoethyl)-1,3-dihydro-1,3-dimethyl-5-methoxy-2H-indol-2-one, can be enriched by contact with a chiral tartaric acid in an amount sufficient to preferentially precipitate a salt of the chiral acid and one of the enantiomers. The product can be used in the synthesis of stereospecific forms of physostigmine and related compounds having pharmaceutical activity.

权利人:MOMENTIVE PERFORMANCE MAT INC
摘要:The invention relates to a process for the stepwise synthesis of silahydrocarbons bearing up to four different organyl substituents at the silicon atom, wherein the process includes at least one step a) of producing a bifunctional hydridochlorosilane by a redistribution reaction, selective chlorination of hydridosilanes with an ether/HCl reagent, or by selective chlorination of hydridosilanes with SiCl 4 , at least one step b) of submitting a bifunctional hydridochloromonosilane to a hydrosilylation reaction, at least one step c) of hydrogenation of a chloromonosilane, and a step d) in which a silahydrocarbon compound is obtained in a hydrosilylation reaction.

标 题 :Process for regenerating noble metal catalyst for the synthesis of hydrogen peroxide according to the anthraquinone process
发明人：SCHREYER GERD; THEISSEN FERDINAND; WEIBERG OTTO; WEIGERT WOLFGANG
权利人:DEGUSSA
摘要:In situ regeneration of noble metal catalysts for the synthesis of hydrogen peroxide by the anthraquinone process is provided by employing as the working solution coming from the extraction or desorption step and being introduced into the hydrogenation step a solution which contains at least 250 mg/liter of hydrogen peroxide, to thereby completely regenerate the noble metal catalyst by full capacity of the hydrogenation step.
