摘要： 研究了N1923萃取磷酸的性能,考察了溶剂和温度对萃取平衡的影响,用斜率法、饱和法以及红外光谱、核磁共振谱确定了不同条件下萃合物的组成。

Abstract: The extraction behaviour of phosphoric acid with primary amine N1923 has been studied in detail.The influence of the solvent upon the extraction equilibrium has been discussed.The composition of extracted complex under different conditions has been determined with the methods of slope, saturation, IR and NMR. The behaviour of water in the extraction process has been approached.The composition of extracted complex determined by saturated method is (RH)H2PO4·6H2O when the concentration of phosphoric acid is low, and (RH)H2PO4·H3PO4·7H2O or (RH)H2PO4·2H3PO4·9H2O when the concentration of phosphoric acid is high.
