Abstract: Rosin, a renewable and abundant resource, has been extensively processed and chemically modified to endow it with special properties, especially in the surfactant industry. In this study, four rosin-based quaternary ammonium asymmetric gemini surfactants (RGS-2-n) with different alkyl chain lengths (n = 12, 14, 16, 18) were synthesized using a simple two-step method based on dehydroabietylamine as the raw material. The feasibility of these surfactants for cleaning purposes was comprehensively evaluated, suggesting that the surfactants own high surface activity and good cleaning performance. Furthermore, by successfully introducing the amine group of dehydroabietylamine into the hydrophilic group of the surfactants, we avoided its potential harm to the environment and water pollution. Density functional theory proves rosin-based gemini surfactants with asymmetric structure can further improve cleaning efficiency. Overall, our findings suggests that RGS-2-n surfactants are promising and sustainable candidates for cleaning electric plates, and provide new opportunities for rosin application in the electric industry.
