| abstract | PURIFICATION OF CRUDE ADIPONITRILE CONTAINING ACRYLONITRILE, PROPIONITRILE, HYDROZYPROPIONITRILE AND BIS-CAYANOETHYL ETHER (BCE) BY DECOMPOSING THE BCE BY TREATING THE CRUDE AT ABOUT 0 TO 400*C. IN THE PRESENCE OF PREFERABLY ABOUT 0.001 TO 0.1 MOLE OF A POLYVALENT METAL CATALYST IN A VALENCE STATE OF AT LEAST 3 PER MOLE OF BCE. THE METAL CATALYST IS AT LEAST ONE COMPOUND OF CHROMINUM, MANGANESES, MOLYBDENUM, TUNGSTEN, AND/OR RHENIUM. THE METAL CATALYST MAY BE AN OXIDE OR ALKALI METAL, ALKALINE EARTH METAL, OR AMMONIUM COMPOUNDS CONTAINING AS THE ANIONIC PORTION THEREOF AN OXYGEN-POLYVALENT METAL MOIETY WHERE THE POLYVALENT METALIS AS STATED ABOVE. SUTIABLE ANIONS INCLUD CHROMATES, MANGANATES, ETC.; BICHROMATES, PERMANGANATES, ECT.; MONOSUBSITUTED CHROMIC SULFATE, MONOSUBSTITUTED MANGANIC SULFATE, ETC. |
