INTERPHASE INTERACTIONS ON THE OIL-WATER INTERFACE IN THE PRESENCE OF ANIONIC SURFACTANTS
Abstract
The effect of anionic surfactant alkyl chain structure on the processes occurring at oil–surfactant solution interface and structure formation in water solution, has been studied. The criteria for evaluating anionic surfactants҆ efficiency have been formulated. It has established that their behavior at the oil–water interface is governed not only by the linearity and saturation of the alkyl group, but also by its length and presence of aromatic ring in its structure. The regularities found are in agreement with the data on the ability of anionic surfactant solutions to wash off oil from metal surface, structural and rheological properties of their water solutions. It has been shown that anionic surfactants effectively reduce the interfacial tension at the oil – water and stabilize the drops of oil thus improving the processes of recovery, preparation and transportation of heavy oil.
