摘要:The present disclosure provides a method for producing one or more intermediates for the synthesis of one or more ionizable lipids, the method comprising: (i) producing a beta-ketoacid by reacting a cyclic ester, a terminal hydroxyester or a derivative thereof, a dicarboxylic acid half ester, or an acid chloride derivative of the dicarboxylic acid half ester, in a condensation reaction, thereby producing the beta-ketoacid or a beta-ketoester that is hydrolyzed to produce the beta-ketoacid; and (ii) decarboxylating the beta-ketoacid, thereby producing the one or more intermediates, wherein the one or more intermediates have a structure that may be defined by Formula A. Further provided is a method for producing ionizable lipid from the intermediate comprising adding an ionizable head group moiety to (a) a ketone group of one or more intermediates having the structure that may be defined by Formula A; or (b) a corresponding alcohol of the intermediate.

摘要:Process for synthesizing and purifying polyol fatty acids polyesters or other nondigestible fats selected from the group of esterified linked alkoxylated polyols and esterified epoxide extended polyols, in which unreacted lower alkyl ester is recovered from a reaction mixture and recycled for use in the synthesis of the nondigestible fat. The process includes the steps of reacting an excess of lower alkyl ester with polyol to esterify hydroxyl groups thereof and form polyol fatty acid polyester, separating at least a portion of the unreacted lower alkyl ester from the polyol fatty acid polyester, and recycling the separated unreacted lower alkyl ester for further reaction with polyol or partially esterified polyol. The recycled lower alkyl ester is substantially free of lower alkyl ester degradation reaction products, such as carbonyls and free fatty acids.

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.

标题 :Process for the synthesis of ethanol and acetaldehyde using cobalt compounds with novel promoters
发明人：LIN JIANG-JEN; KNIFTON JOHN F
权利人:TEXACO INC
摘要:Ethanol and/or acetaldehyde are prepared in good yield by contacting methanol, hydrogen and carbon monoxide with a catalyst system comprising a cobalt-containing compound and a promoter in the presence of an inert oxygenated solvent at a temperature of from about 50 DEG C. to about 350 DEG C. and a pressure of at least 500 psig or greater. The combination of cobalt-containing compound and promoter may be (a) a cobalt-containing compound with an organo-sulphur compound, (b) an iodide-containing cobalt compound with a nitrogen-containing compound as promoter, and (c) a cobalt-containing compound with 1,1'-bis(diphenylphosphino)ferrocene.
