A process is described for the activation of zeolitic catalysts containing titanium having the formula: xTiO(1-x)SiOwherein x ranges from 0.0001 to 0.4, which consists in treating said materials with a solution of an ammonium salt of a carboxylic acid and subsequently subjecting them to calcination. The catalysts thus treated have higher catalytic performances with respect to those not treated, in oxidation processes of organic substrates.

Process for the activation of zeolitic catalysts containing titanium and their use in oxidation reactions

The invention relates to a purification method of cyclohexanone-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.
