Abstract RU 2042611 C1

FIELD: concentration of diluted sulfuric acid. SUBSTANCE: invention eliminates basic causes of acid losses, i.e. decomposition and foaming, by heating it to 110-150 C (below its boiling temperature) and by removal of water in the form of azeotrope with benzene introduced into the system in a vapor or liquid phase.
