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.

标题:Slurry process for synthesis of bisphosphites and situ use thereof for producing bisphosphite
发明人：MILLER GLENN A
权利人:MILLER GLENN A; DOW TECHNOLOGY INVESTMENTS LLC
摘要:The present invention provides a step-wise process for preparation of a bisphosphite. In step (a) the process prepares a phosphoromonochloridite in high yield, by contacting phosphorus trichloride with an aromatic diol in a slurry under reaction conditions and in the presence of a second aromatic diol to produce a mixture comprising the phosphoromonochloridite, the second aromatic diol, and excess PCl3. The slurry comprises less than 5 mole percent of a nitrogen base, and the organic solvent is selected for its low hydrogen chloride solubility. After removing the excess PCl3, a nitrogen base is added to effect condensation of the phosphoromonochloridite with the second aromatic diol to yield the bisphosphite. The invention particularly provides a process for preparing 6,6′-(3,3′,5,5′-tetra-tert-butylbiphenyl-2,2′-diyl)bis(oxy)didibenzo[d,f][1,3,2]dioxaphosphepine by the above route.
