Abstract Waste cooking oils and non-edible vegetable oils are abundant and
renewable resources for bio-based materials which have showed great potential
applications in many industries. In this study, five fatty acids commonly found
in non-edible vegetable oils, including palmitic acid, stearic acid, linoleic acid,
linolenic acid, ricinoleic acid, and their mixtures, were used to produce bio-based
zwitterionic surfactants through a facile and high-yield chemical modification.
These surfactants demonstrated excellent surface/interfacial properties with the
minimum surface tensions ranging from 28.4 mN/m to 32.8 mN/m in aqueous
solutions. The interfacial tensions between crude oil and surfactant solutions were
remarkably reduced to lower values… More >
