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.
