Abstract: To study the relationship between the "tail" structure and the behavior of Gemini surfactants in aqueous solution, the thermodynamic parameters of micellization of a new Gemini surfactant CsH2s-α,ω-bis(dehydroabietylhydroxypropylteteramethylethylammonium chloride), with dehydrogenated rosin as hydrophobic "tails" in the structure were investigated. When enthalpy of interaction(ΔH) was plotted against entropy(ΔS),linear plots were obtained. This indicates the clear enthalpy-entropy compensation with a compensation temperature of approximately 310.8 K.

Key words: Gemini surfactant, enthalpy-entropy compensation, rosin
