Synthesis and Properties of an Imidazole Quaternary Ammonium Gemini Surfactant
An imidazole quaternary ammonium Gemini surfactant was synthesized with imidazole,1,4-dibromobutane and 1-bromohexadecane as main raw materials under ultrasound conditions.The structure of product was analyzed by FTIR and melting point measurement.And the critical micelle concentration(CMC)of the product was determined by liquid refractive index method,the foam and emulsification properties of the product were studied.The experiment result showed that the yields of product was 82.7%,CMC = 2.5×10-3 mol/L,high foam stability,strong foaming ability,good emulsification ability,the product is a kind of good performance O/W emulsifier,which can be used in daily chemical,leather,paper making,textile printing and dyeing,petrochemical and other fields.
