Design and Properties of Natural Rosin-Based Phosphoester Functional Surfactants.

ABSTRACT: As an important forestry biomass resource, rosin has a wide range of applications in medicine, adhesives, surfactants and other fields. Using natural dehydroabietic acid as a raw material, dehydroabietic acid-based phosphorus monoester (DPM) and diester (DPD) surfactants were designed and synthesized. The chemical structures and self-assembly properties were characterized by FT-IR, NMR and TEM, and the effects of pH on critical micelle concentration, γ_CMC, emulsifying properties, foam properties and micelle morphology were studied. The results showed that the CMC, γ_CMC value and aggregate morphology had certain pH responsiveness. The γ_CMC value under acidic conditions was smaller than γ_CMC under alkaline conditions, and the foaming performance an
