Abstract:Amphiphilic polyamides represent a class of surfactants with vast potential for applications. In this work, fatty acid methyl esters (methyl oleate and methyl erucate) and biomass-derived 1,4-butanediamine were utilized as raw materials to synthesize two novel anionic polyamide surfactants (APSs, C18:1-PEA and C22:1-PEA). The structure of APSs was characterized via 1H nuclear magnetic resonance (1H NMR) spectra, Fourier transform infrared (FT-IR) spectra, and gel permeation chromatography (GPC). The physico-ch… Show more
