标 题:Process for reducing the levels of fatty acid contaminants in polyhydroxy fatty acid amide surfactants

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.

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.

标题:Surfactantless synthesis of amphiphilic cationic block copolymers
发明人：PARKER DANE KENTON; KULIG JOSEPH JOHN
权利人:GOODYEAR TIRE & RUBBER
摘要:The present invention is directed to a method of producing an amphiphilic block copolymer, including the steps of:n (1) preparing a first aqueous polymerization medium which is comprised ofn (a) 4-vinylpyridine, (b) a trithiocarbonate RAFT agent, and an emulsifier, wherein the emulsifier is prepared in-situ within the aqueous polymerization medium by the reaction of a latent surfactant with a surfactant activator; n (2) polymerizing the 4-vinylpyridine within the first aqueous polymerization medium in the presence of a first free radical initiator to produce a poly(4-vinylpyridine); (3) protonating the poly(4-vinylpyridine) to form a protonated poly(4-vinylpyridine) RAFT macroinitiator; (4) preparing a second aqueous polymerization medium which is comprised of the protonated poly(4-vinylpyridine) RAFT macroinitiator and a monomer containing ethylenic unsaturation but is exclusive of a surfactant; and (5) polymerizing the protonated poly(4-vinylpyridine) RAFT macroinitiator and monomer containing ethylenic unsaturation within the second aqueous medium in the presence of a second free radical initiator and a temperature less than 100° C. to produce an amphiphilic block copolymer of the 4-vinylpyridine and monomer containing ethylenic unsaturation.
