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.
