Method for producing peroxymonosulfuric acid (also known as persulfuric acid, peroxysulfuric acid, or Caro's acid)

摘要

Disclosed is an apparatus when used to continuously produce peroxymonosulfuric acid (H2SO5, also known as persulfuric acid, peroxysulfuric acid, or Caro's acid), comprising: a) a first static mixer for mixing hydrogen peroxide with sulfuric acid to react them, thereby obtaining a reaction solution; b) a second static mixer for mixing the reaction solution obtained in the first static mixer with a dilution water; and c) a reaction solution transporting pipe for transporting the reaction solution from the first static mixer to the second static mixer; with the first static mixer and the reaction solution transporting pipe being disposed underwater in a vessel thereby cooling the reaction solution to a temperature range of 25 degree C-50 degree C within five minutes after initiation of the mixing of the hydrogen peroxide with sulphuric acid.
