标题:Process for synthesis of isobornyl (Meth) acrylate
发明人：KNEBEL JOACHIM; SAAL DORIS
权利人:ROEHM GMBH
摘要:The present invention relates to processes for synthesis of isobornyl (meth)acrylate by reacting camphene with (meth)acrylic acid in the presence of sulfuric acid and at least one compound having inhibiting action. Aqueous sulfuric acid with an acid concentration in the range of 65 to 85 wt % is used. Isobornyl (meth)acrylate can advantageously be distilled from a mixture containing sulfuric acid in the presence of 2,6-di-tert-butyl-alpha-(dialkylamino)-p-cresol.

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.
