用液上气相色谱法测定了NH_2-CO_2-NaCl-H_2O体系的气液平衡数据,并用计算机进行了数据处理,得到的关联式适用于纯碱生产涉及到的温度和浓度范围。logP_(NH_3)=7.5219—1834.4/T—0.02100[F_(NH_3)—1.3509 [CO_2]/[F_(NH_3)]+1.002610g[F_(NH_3)] logP_(CO_2)=11.1045—3938.5/T+0.009136[F_(NH_3)]+5.8999 [CO_2]/[F_(NH_3)] logP_(H_3O)=9.1181—2336.9/T
The gas-liquid equilibrium data of NH_2-CO_2-NaCl-H_2O system were determined by liquid chromatography and the data were processed by computer. The correlations obtained were suitable for the temperature and concentration range of soda ash production. logP_ (NH_3) = 7.5219-1834.4 / T-0.02100 [F_ (NH_3) -1.3509 [CO_2] / [F_ (NH_3)] + 1.002610g [F_ (NH_3)] logP_ (CO_2) = 11.1045-3938.5 / T + 0.009136 [F_ (NH_3)] + 5.8999 [CO_2] / [F_ (NH_3)] logP_ (H_3O) = 9.1181-2336.9 / T
