Synthesis and Properties of Novel Cashew-Based Sulfonate Gemini Surfactant

Abstract:

A novel cashew-based gemini surfactant was synthesized from cashew phenol, 1, 3-dibromopropane and chlorosulfonic acid through etherification, sulfonation and neutralization. The critical micelle concentration (cmc) for cashew-based gemini surfactant was 6.2×10^-2 mmol·L^-1, the surface tension (γ_cmc) was 36.92 mN.m^-1. Foam properties and emulsification properties were investigated including the affection of inorganic salts and sodium hydroxide. The oil / water interfacial tension can be decreased efficiently to 10^-3mN / m.
