| Abstract: | The intermediate(2,3-epoxypropyl)dimethyl-ammonium chloride was prepared by N,N-Dimethyl dodecylamine and epichlorohydrin as main monomer.Then the target product(2-hydroxy-3-lauryl acyloxypropyl) dodecyl dimethyl ammonium chloride was obtained by reacting the intermediate and the laurie acid.synthesis processes were studied and reaction conditions were optimized.Structure of target product was characterized by infrared spectrum,1H-NMR and 13C-NMR.Sulface activities of the product were measured.They were cri... |
