摘要
测定了２５℃和１００℃时Ｈ３ＢＯ３－Ｎａ２ＳＯ４－ＮａＣｌ－Ｈ２Ｏ体系的固液平衡数据并绘成相图，应用相图分析了ＮａＣｌ作盐析剂分离Ｈ３ＢＯ３的生产过程，为硼砂硫酸酸化制取Ｈ３ＢＯ３的生产工艺改进提供了一定的理论基础。
The solubilities of H3BO3-Na2SO4-NaCl-H2O system at 25and 100were determined and
the phase diagrams were plottedOn the basis of these diagrams, manufacture process of
separation H3BO3 from Na2SO4 wasanalysed with NaCl as salting out agent These results
provide a certain theory foundation for the technology improvement of producing H3BO3 through
borax acidification by sulfuric acid
