N,N-Dimethyloctadecylamine Fa'atasi ai ma le CAS 124-28-7 Mo Surfactants
Vai enaena vaivai ma mafiafia, samasama vaivai ma malō i le 20℃. E mafai ona solo i vailaʻau faʻamalūlūina o le ava malosi, e le solo i le vai. E ala i le octadecylamine, formaldehyde, formic acid e maua mai le condensation. Muamua faʻaopopo le octadecylamine i totonu o le reactor, faʻafefiloi tutusa i le ethanol medium, pulea le vevela i le 50-60 °C, faʻaopopo le formic acid, faʻafefiloi mo ni nai minute, faʻaopopo le formaldehyde i le 60-65 °C, faʻavevela i le 80-83 °C, toe faʻafoʻi mo le 2 itula, faʻaleaogaina i le caustic soda vai e faʻateleina ai le pH i le 10, tuʻu mo le stratification, aveese le vai, aveese le ethanol i le vacuum distillation, ona faʻamālūlū lea e maua ai le N,N-dimethyloctadecylamine.

O lenei oloa o se vailaʻau taua e faʻaputu ai le quaternary ammonium salt type cationic surfactant. E mafai ona tali atu i le ethylene oxide, dimethyl sulfate, diethyl sulfate, methyl chloride, benzyl chloride, ma isi mea e faʻatupu ai ni quaternary ammonium salt cations eseese, e mafai ona faʻaaogaina mo le faʻamalūlūina o ie, vailaʻau e teteʻe i le vevela, faʻaleleia atili ai le faigofie ona selu lauulu ma isi oloa. E mafai foʻi ona faʻaaogaina e gaosia ai vailaʻau e teteʻe ai iniseti. E tali atu le N,N-Dimethyloctadecylamine ma le ethylene oxide ma le nitric acid e maua ai le octadecyldimethylhydroxyethyl quaternary ammonium nitrate, o se vailaʻau e teteʻe i le vevela.
