| Abstract: | 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 |
