摘要
以 N,N-二甲基十二烷基叔胺和 1 ,3-二溴丙烷为原料 ,无水乙醇为溶剂合成阳离子型Gemini表面活性剂。反应产物以混合溶剂乙酸乙脂 -乙醇重结晶纯化后 ,用红外光谱及核磁共振进行结构表征 ,并将其作为晶形改变剂及助乳剂应用于乳胶基质中 ,使乳化炸药具有小而分布均匀的 W/
Cationic Gemini Surfactant was synthesized from N,N dimethyl dodecyltetiary amine and 1,3 propyl dibromide by using ethanol as solvent.After being recrystallized in the ethyl acetate ethanol solvent mixture, the Gemini product was qualiatively detected and verified by IR and 1HNMR.The emulsion explosive,which uses the Gemini surfactant as crystal shape modifier and auxiliary emulsifier,has smaller W/O type particle size and better distribution, stability and explosion properties.
