专利号:US-2012277444-A1 优先权日:2011-04-27 标 题:Synthesis of hydroxyalkyl amides from esters 发明人:MAHADEVAN SHIVKUMAR; VENKATASUBBAN KUNISI 权利人:MAHADEVAN SHIVKUMAR; VENKATASUBBAN KUNISI 摘要:Hydroxyamides are synthesized from esters. A process of making hydroxyalkyl amides comprises: reacting an ester with a hydroxyalkyl amine having the formula H 2 N—R 3 —OH wherein R 3 is a substituted or unsubstituted C2 to C5 alkyl, in the presence of a catalyst in an anhydrous solution to form the hydroxyalkyl amides. Monomers suitable for formation of polymeric articles can utilize these hydroxyamides.
专利号:US-5188769-A 优先权日:1992-03-26 标 题:Process for reducing the levels of fatty acid contaminants in polyhydroxy fatty acid amide surfactants 发明人:CONNOR DANIEL S; SCHEIBEL JEFFREY J; MURCH BRUCE P; MAO MARK H; GOSSELINK EUGENE P; SEVERSON JR ROLAND G 权利人:PROCTER & GAMBLE 摘要:The synthesis of polyhydroxy fatty acid amide surfactants exemplified by the compound C11H23C(O)N(CH3)CH2[CHOH]4CH2OH by reacting a fatty acid ester with an N-alkyl sugar amine can result in contamination of the product surfactant by residual sources of fatty acids. These residual fatty acids may be unacceptable in high sudsing detergent compositions, such as dishwashing liquids, especially with Ca or Mg cations. The process of this invention reacts such contaminants with alkyl amines or, especially, ethanolamine, to convert them into fatty alkyl- or alkanolamides, which are quite acceptable in fully-formulated detergent compositions for home or industrial use.
专利号:WO-9522519-A1 优先权日:1994-02-17 标题 :Synthesis of polyhydroxy fatty acid amides from triglycerides 发明人:SCHEIBEL JEFFREY JOHN; REILMAN RANDALL THOMAS; SHERMAN JOE FREDERICK 权利人:PROCTER & GAMBLE 摘要:Fats and oils such as hardened palm kernel oil are reacted directly with N-substituted polyhydroxy amines to provide high yields of N-substituted polyhydroxy fatty acid amide surfactants having improved odors and low fatty acid content. Hardened palm kernel oil is reacted with N-methylglucamine in the presence of an ethoxylated alcohol, but in the absence of methanol solvent, using sodium propylene glycolate catalyst to provide the mixed corresponding fatty acid amide of N-methylglucamine.
专利号:US-4780542-A 优先权日:1983-09-26 标 题:Process for the synthesis of esters and amides of carboxylic acids 发明人:LALEZARI IRAJ 权利人:MONTEFIORE MED CENTER 摘要:The invention relates to the preparation of an ester or an amide from an anhydride with an alcohol or an amine, wherein the anhydride is first prepared by reacting an acid and an alkyl chloroformate in a 100% aqueous medium, that is, 100% water.
