PROCESS FOR THE REMOVAL OF SULFURIC ACID PRESENT IN ESSENTIALLY ALCOHOLIC SOLUTIONS OF H202 COMING FROM DIRECT SYSTHESIS |
摘要 |
Process for the removal of impurities, in particular sulfuric acid, present in solutions of H2O2 coming from direct synthesis starting from hydrogen and oxygen, fed from a reactor containing a palladium and platinum catalyst, in an alcohol-based liquid reaction medium containing sulfuric acid and a halogen as promoters, which comprises: a) adding to the solution of H2O2 an at least stoichiometric quantity with respect to the sulfuric acid present, of carbonates and/or bicarbonates and/or oxides and/or hydrox ides of alkaline and/or alkaline earth metals; b) removing the solid precipitated from the liquid phase. |
