Synthesis and Properties of a New Gemini Surfactant with Amide Group as Spacer

Abstract:

A new Gemini surfactant was synthesized with chloroacetyl chloride, urea and N, N-dimethyl dodecyl amine as raw materials. Its structure was verified by IR and ¹HNMR. The surface active properties of the Gemini surfactant in water was measured at room temperature. Results indicate that the bisquaternary ammonium salt exhibits lower the critical micelle concentration(CMC) and surface tension at the CMC (γ_cmc), compared with conventional surfactant C₁₂TAB. The sterilizing antimicrobial performance of the Gemini Surfactant shows excellent bactericidal activities against Magnaporthe grisea and Bipolaris sorokiniana compared with C₁₂TAB at 50 mg/L.
