Abstract
Using bromotetradecane and N-methyl-diethanolamine(MDEA)as raw materials,Tetradecyl dimethyl hydroxyethyl ammonium bromide(TMDAB)was synthesized by solvent-free synthesis.The structure and molecular weigh of the product were characterized by IR,1 H NMR and MS.Through single factor test the optimal reaction conditions were as following:temperature was 110 ℃,n(bromotetradecane)∶n(MDEA)=1.1∶1.0,reaction time was 110min.The conversion rate was up to 90%under the amplification experiments of 40magnification.The results showed that the surface tension was 24.8mN· m-1,the product had good performance solubility properties foaming and emulsification.
