摘要
The invention concerns synthesized amido-amine-based cationic gemini surfactants with flexible and rigid spacers and different hydrophobic. These gemini surfactants were prepared by modified procedure through amidation of long chain carboxylic acids using 3-(dimethylamino)-1-propylamine followed by treatment with halohydrocarbons and showed excellent thermal stability and surface properties useful for various oilfield applications such as enhanced oil recovery.
