PROCESS FOR THE PRODUCTION OF CYCLOHEXANONE OXIME

THE INVENTION RELATES TO A PROCESS FOR PRODUCTION OF CYCLOHEXANONE OXIME IN WHICH A PHOSPHATE-CONTAINING AQUEOUS REACTION MEDIUM IS CYCLED FROM A HYDROXYLAMMONIUM SYNTHESIS ZONE TO A CYCLOHEXANONE OXIME SYNTHESIS ZONE AND BACK TO THE HYDROXYLAMMONIUM SYNTHESIS ZONE, IN WHICH HYDROXILAMONIUM SYNTHESI...

Zusammenfassung:THE INVENTION RELATES TO A PROCESS FOR PRODUCTION OF CYCLOHEXANONE OXIME IN WHICH A PHOSPHATE-CONTAINING AQUEOUS REACTION MEDIUM IS CYCLED FROM A HYDROXYLAMMONIUM SYNTHESIS ZONE TO A CYCLOHEXANONE OXIME SYNTHESIS ZONE AND BACK TO THE HYDROXYLAMMONIUM SYNTHESIS ZONE, IN WHICH HYDROXILAMONIUM SYNTHESIS ZONE HYDROXYLAMMONIUM IS FORMED BY CATALYTIC REDUCTION OF NITRATE WITH HYDROGEN, AND WHICH CYCLOHEXANONE OXIME SYNTHESIS ZONE HYDROXILAMMONIUM IS REACTED WITH CYCLOHEXANONE TO FORM CYCLOHEXANONE OXIME, WHERE THE CONCENTRATION HYDROXYLAMMONIUM IN THE AQUEOUS REACTION MEDIUM ENTERING THE CYCLOHEXANONE OXIME SYNTHESIS ZONE IS HIGHER THAN 1.0 MOL/L..
