Synthesis and Performance Evaluation of Nonionic Surfactants Based on Amber Acid Derivatives
摘要
Abstract
Two nonionic surfactants were synthesized using N-dodecylsuccinic anhydride,L-leucine,and polyether alcohol as materials.In order to study the aggregation morphology and properties of these two surfactants,their surface tension at different concentrations was tested and the critical micelle concentration(CMC)was determined based on the γ-lgc curve.The molecular dynamics simulation techniques was used to study the aggregation pattern of surfactants at the oil-water interface and the interaction with oil and water.The results showed that compared to surfactant 1,surfactant 2 had more nonionic hydrophilic components and thus reducing surface tension was more effective.The critical surface tensions(γCMC)of surfactant 1 and surfactant 2 were 25.54 and 24.46 mN/m.At low concentration,both of the two nonionic surfactants have high water precipitation rate and poor emulsification effect,but at high concentration,the emulsification effect is better,and the lotion prepared with two nonionic surfactants has certain stability.The electrostatic potential distribution of surfactant molecules affects their hydrophilic and oleophilic properties.关键词
