摘要
介绍了混合溶剂法在无机盐特别是硫酸钾生产中的应用及发展研究 ;测定了 2 5℃ ,乙醇浓度为 2 5 .2 8%(wt%)时 ,Na+ ,K+ / / Cl-,SO2 -4 - C2 H5OH- H2 O体系的部分溶解度数据 ,绘出了干盐图 ,并与 2 5℃时水溶液相图进行比较 ,探讨了应用前景 .
A study is made of the method of mix-solvent in the manufacture of K\-2SO\-4. Some solubilities of the system of Na\++,K\++//Cl\++,SO\+\{2-\}\-4-C\-2H\-5OH-H\-2O(C\-2H\-5OH weight is 25.28% (wt%) in solvent) at 25℃ have been obtained.A comparison made with Na\++,K\++//Cl\+-,SO\+\{2-\}\-4-H\-2O at 25℃ and the application of this system is discussed.
