摘要
Surfactants can play major role in increasing oil recovery factor through interfacial tension reduction. In the present study, a new synthetic method was used to prepare (S)-2-amino-6-dodecanamidohexanoic acid, an amino acid-based surfactant then it was applied as an oil recovery agent for the first time. The structure of this surfactant was studied using FTIR and H-1 NMR spectroscopy. The critical micelle concentration was found to be value is 0.4-0.5 wt% using surfactant solution conductivity, pH, and IFT methods. A 56.50% reduction of IFT was recorded using this environmentally friendly surfactant.
