摘要：The use of calcium-resistant surfactants in household and industrial washing applications may simplify the formulation composition of laundry and therefore reduce costs. A series of bio-based surfactants, N-alkyl furfuryl methylamine sulfonates (AFMS), was developed from the biomass-derived furfural and aliphatic amines by a simple and effective method. The structure of these bio-based surfactants was characterized by gas chromatography-mass spectrometry (GC-MS), liquid chromatography-mass spectrometry (LC-MS) and 1H nuclear magnetic resonance (NMR) spectroscopy. These bio-based surfactants demonstrated low surface tension, high emulsification and high decontamination efficiency. Meanwhile, the AFMS surfactants exhibited excellent calcium resistance, maintaining micelle stability in Ca2+ up to 2.16×104 mg/L and the solution clarification in Ca2+ up to 7.21×104 mg/L. Furthermore, the AFMS surfactants had a stable decontamination effect in hard water. The wetting ability, foaming ability, toxicity and biodegradability parameters were also evaluated. Therefore, the AFMS surfactants synthesized in this work could be applied as a more efficient and promising bio-based surfactant candidate for application in household and industrial washing. ? 2024 ICE Publishing.
