Abstract
A procedure for preparing ketazines of the formula: **(See formula)** where R1 and R2 are linear or branched alkyl radicals, cycloalkyl with a maximum of 10 carbon atoms or phenyl, optionally substituted with stable radicals in the reaction medium, or together a linear or branched alkylene radical of 3 to 11 carbon atoms, whose procedure is to oxidize a secondary alcohol of formula **(See formula)** where R1 and R2 have the meaning given above, in liquid phase, using oxygen, molecular or a gaseous mixture containing it, at a temperature of 60º to 180ºC and then reacting the mixture obtained with ammonia in the presence of a nitrile R3 (-CN) n, selected from mononitriles and polynitriles where n has a value between 1 and 6 and where R3 is a hydrocarbon radical containing up to 12 carbon atoms and which may be acyclic or cyclic or contain an aromatic nucleus selected from benzene and pyridic nuclei, which may be substituted with 1 to 6 the same or different groups, preferably selected from those which are not oxidized under the reaction conditions, such as amide, carboxylic acid and ester groups, fluorine, chlorine, bromine, iodine, nitro, amino oxide, hydroxy, acetal and ether.
