| Abstract: |
Cationic gemini surfactants based on Guava fat mixed fatty alcohols and isolated fatty alcohols C8, C12, C16, C18 were synthesized. The surface properties and thermodynamic parameters of micellization process, of the new cationic gemini surfactants have been investigated. Furthermore, the petroleum-collecting and dispersing indices of obtained surfactants, inwaters of varying salinity have been studied. The results revealed that the tendency of these surfactants toward adsorption processwasmore than its tendency micellization and showhigh petroleumcollecting and dispersing properties. |
