| Abstract: | For the aim of fertilizer studying, the solubility and refraction indices of the quaternary system KCI-KH2PO4-CO (NH)2-H2O have been investigated by isothermal method at 298.2K first time. The system is simple eulonic type, whose eulonic point is KCI 13. 31,KH2PO4 3. 33,CO (NH2)2 47. 26, H2O 36. 10g/100g saturacted solutions. |
