Synthesis and properties of pyridine Gemini surfactants containing amide spacer
摘要
Abstract
Abract:Pyridine Gemini surfactant containing amide spacer was synthesized using ethylenediamine, 1-bromoalkane,chloroacetyl chloride and pyridine as raw materials by halogenation amidation reaction and quaterisation. The target product synthesis condition is as following:ultrasonic for assisting reaction was 40kHz and 100W,reaction temperature was 60℃,and reaction time was 5h. The target products were characterized by FTIR,1H NMR and13C NMR. The major performance of target products was investigated,including critical micelle concentration and bactericidal property. The results show that the cmcof target product is 1.4×10−2~2.3×10−5mol/L,and has a good emulsification and stability. The antibacterial effect of surfactant with eight carbon alkyl chains for escherichia coli and bacillus subtilis is the best.关键词
