为利用Engel复盐法制备碳酸钾，本文研究了三元体系K2CO3-KHCO3-H2O在KHCO3在289K时的相平衡，并测定溶液密度，绘制出体系的溶解度图和溶液密度一组成关系图，通过相图研究得出三元体系的共饱点及相关性质，为最终获得生产相图奠定基础。

The ternary systems K2CO3 -KHCO3 -H2O at 289 K are studied the density of the phase equi- librium solutions for the preparation of potash using engel double salt are determined, the equilibrium figure of the ternary systems K2CO3 - KHCO3 - H2O and the densities of the equilibrium solutions in this systems,is to drawed up through studies and get ternary systems＇related properties ,which lays the foundation for the obtaining of the final phase diagram in production.
