【Abstract】 The special designed surface active agent for the synthesis of nitride magnetic fluid was investigated with diethylenetriamine and oleic as raw materials. Many kinds of surface active agents in amide series were composed using solvent method. Applying these surface activators in the process of nitride iron preparation, the nitride magnetic fluid was obtained with higher saturated magnetic intensity and better chemical stability, and optimized process variables were determined for the synthesis of surface active agents. Among the process parameters, the mixture ration between diethylenetriamine and oleic and the temperature plays an important role for the property of surface active agents.更多还原
