Investigation of potassium perrhenate reduction in hydrochloric acid solution by the method of electron spectroscopy

The investigation of potassium perrhenate reduction in hydrochloric acid by hydrogen at increased pressure and temperature (100-350 deg C) by the method of electron spectroscopy has shown that there exists in the solution equilibrium between Resup(4+) mono- and polymeric forms, on the one hand and Resub(2)sup(6+) binuclear complexes - on the other. The conditions ensuring maximum equilibrium shift towards formation of Resub(2)sup(6+) binuclear complexes have been found
