专利号:US-4920204-A 优先权日:1987-11-12 标题:Ceric hydrocarbyloxy nitrates and their use in organic synthesis 发明人:GRADEFF PETER S; SCHREIBER FRED G; GROSBOIS JEAN; MAUERMANN HEIKO 权利人:RHONE POULENC IND 摘要:Ceric hydrocarbyloxy nitrates having the general formula: x = 1, 2 or 3 are obtained by reaction of ceric ammonium nitrate with x moles of ammonia and an aliphatic, cycloaliphatic or aromatic alcohol having from two to twenty carbon atoms, and are useful in the preparation of ceric hydrocarbyl oxides difficult or expensive of access by other routes, and in synthesis of other organic ceric compounds.
专利号:US-6166212-A 优先权日:1999-05-20 标 题 :Process for the synthesis of N-(hydroxyalkoxy) substituted hindered amine stabilizers 发明人:GALBO JAMES P; DETLEFSEN ROBERT E; DIFAZIO MICHAEL P; GRACE HENRY C; KUELL CHRISTOPHER 权利人:CIBA SC HOLDING AG 摘要:N-(Hydroxyalkoxy) hindered amine stabilizers are prepared by reacting the corresponding N-oxyl compound with a peroxide or organic hydroperoxide and a catalytic amount of a metal salt or metal-ligand complex in an alcohol solvent. These N-(hydroxyalkoxy) hindered amines are particularly useful as stabilizers for polyolefins, thermoplastic polyolefins and automotive coating compositions.
