PROCESS FOR THE REMOVAL OF THE INORGANIC ACID AND METAL IMPURITIES PRESENT IN ESSENTIALLY ALCOHOLIC SOLUTIONS OF HYDROGEN PEROXIDE COMING FROM DIRECT SYNTHESIS

摘要

Process for the contemporaneous removal of inorganic acids and heavy metals present in solutions of H2O2 coming from direct synthesis starting from hydrogen and oxygen, fed to a reactor containing a palladium and platinum catalyst, in an essentially alcoholic liquid reaction medium containing an inorganic acid and a halogen as promoters, which comprises treating the solution of H2O2 by putting it in contact with an anionic exchange resin.
