伯胺N_(1923)萃取硝酸研究

Study on the extracting nitric acid with primary amine N_(1923)

研究了N_(1923)萃取硝酸的性能,考察了溶剂对萃取平衡的影响,用饱和法、斜率法和红外光谱法确定了萃合物组成和萃取机理。

The extraction behaviour of nitric acid with primary amine N_(1923) in CHCl_3 at 20±1℃ has been studied in detail. The influence of the solvent upon the extraction equilibrium has been discussed. The composition of extracted Complex under different condition has been determined with the methods of slope, saturation and IR. The composition of extracted complex is RNH_3NO_3 when the concentration of nitric acid is low, and RNH_3·nHNO_3 when the concentration of nitric acid is high, here on n>1.
