Abstract: A CYCLIC PROCESS FOR THE PREPARATION OF AN OZIME FROM A KETONE AND A HYDROXYLAMMONIUM SALT IS DISCLOSED IN WHICH AN AQUEOUS ACID REACTION MEDIUM IS CIRCULATED BETWEEN A HYDROXLAMMONIUM SALT SYNTHESIS ZONE WHEREIN NITRATE IONS ARE CATALYTICALLY REDUCED TO FORM A HYDROXYLAMMONIUM SALT IN THE AQUEOUS ACID REACTION MEDIUM, AND AN OXIME SYNTHESIS ZONE WHEREIN THE HYDROXYLAMMONIUM SALT IS REACTED WITH KETONE TO FORM AN OXIME. THE NITRATE IONS REDUCED IN THE HYDROXYLAMMONIUM SALT SYNTHESIS ZONE ARE REPLENISHED BY THE ABSORPTION OF NITROUS GASES IN THE AQUEOUS ACID REACTION MEDIUM RESULTING IN FORMATION OF NITRIC ACID.

Abstract: A CYCLIC PROCESS IN WHICH AN AQUEOUS ACID REACTION MEDIUM IS KEPT IN CIRCULATION BETWEEN A ZONE FOR THE SYNTHESIS OF HYDROXYLAMINE AND A ZONE FOR THE SYNTHESIS OF OXIME. A GAS FLOW CONTAINING NO AND SOME NO2 IS CONTINUOUSLY ADDED TO THE CIRCULATING LIQUID, THE GREATER PART OF THE NO IS BEING CATALYTICALLY REDUCED WITH H2 TO FORM NH2OH AND SOME NH3 AS BYPRODUCT. THE NH2OH IS CONSUMED IN THE OXIME SYNTHESIS ZONE AND THE NH3 BYPRODUCT IS CONTINUOUSLY REMOVED BY CONTACTING THE CIRCULATING LIQUID WITH NO AND NO2 UNDER SUCH CONDITIONS THAT N2 AND H2O RESULT.

Abstract: A CYCLIC PROCESS IN WHICH AN AQUEOUS ACID REACTION MIXTURE IS KEPT IN CIRCULATION BETWEEN A ZONE FOR THE SYNTHESIS OF HYDROXYLAMINE AND A ZONE FOR THE SYNTHESIS OF OXIME. NITRIC ACID IS CONTINUOUSLY ADDED TO THE CIRCULATING LIQUID, THE NITRATE IONS BEING CATALYTICALLY REDUCED WITH H2 TO FORM NH2OH AND SOME NH3 AS BY-PRODUCT. THE NH2OH IS CONSUMED IN OXIME SYNTHESIS ZONE AND THE NH3 BY-PRODCUT IS CONTINUOUSLY REMOVED BY CONTACTING THE CIRCULATING LIQUID WITH A MIXTURE CONTAINING NO AND NO2 UNDER SUCH CONDITIONS THAT N2 AND H2O RESULT.
