ABSTRACT
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 1H 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.
