标 题 :Process for the Synthesis of Amine Ethers
发明人：FREY MARKUS; BROENNIMANN VALERIE
权利人:CIBA GEIGY CORP
摘要:The present invention relates to novel processes for the preparation of a sterically hindered amine ether by reacting a corresponding sterically hindered amine oxide with a ketone or an aldehyde with at least one reactive H in the presence of a peroxydisulphate. Products obtained by this process may be hydrogenated. The compounds made by these processes are particularly effective in the stabilization of polymer compositions against harmful effects of light, oxygen and/or heat and as flame-retardants for polymers.

发明人：MURPHY LEANNE DAWN
权利人:XEROX CORP
摘要:Processes for selectively hydrogenating double and/or triple bonds in organic molecules include providing at least one organic molecule containing a double and/or triple bond, providing at least one hydrogen donor molecule, and hydrogenating the double and/or triple bond in the presence of at least one catalyst. Processes for preparing arylamine molecules include selectively hydrogenating double bonds in arylamine compounds by providing at least one organic molecule containing a multiple bond, providing at least one hydrogen donor molecule, and hydrogenating the multiple bond in the presence of at least one catalyst. The processes provide efficient, cost-effective and safe methods for conducting selective hydrogenation reactions in the synthesis of organic molecules, such as charge-transport molecules.
