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:Sugar esters and an improved anhydrous method of manufacture
发明人：KEA SANDRA; WALKER CHARLES E; KLINE ERIC
权利人:NEBRASKA STATE
摘要:The invention relates to an improved process for the synthesis of sugar esters carried out in a substantially anhydrous system and in the presence of an organic acid chloride. Any of the known available sugars may be used and in particular hydrolyzate sugars derived from starch are effectively employed in accordance with the present invention to produce sugar esters having superior emulsifying characteristics for use as an ingredient in food products for human consumption.
