PURIFICATION METHOD OF CYCLOHEXANONE-OXIME

摘要

The invention relates to a purification method of cyclo- hexanone-oxime in a solution of solvents immiscible with water, which consists in washing said solutions with water or with an aqueous solution of a base having a pK <5 or in passing the solutions of cyclohexanone-oxime through a weakly alkaline ion exchange resin and, optionally, also through a weakly acid ion exchange resin.
