A process for preparing a ketone or carboxylic acid by catalytic oxidation of a secondary or primary alcohol comprises adding the secondary or primary alcohol as a raw material and N-hydroxyphthalimide (NHPI) combined with phthalocyanine, serving as a catalytic system, into an amount of an organic solvent into which oxygen gas is then introduced, to proceed with an oxidation reaction to give the ketone or carboxylic acid. The oxygen gas is employed as the source of an oxidant. The oxidation reaction may be carried out under normal pressure at 60 to 120&#xb0; C. for 9 to 36 hours. The process can produce a high yield of ketone or carboxylic acid. Compared with conventional technology, the process has several advantages, such as the green oxidant, the cheap catalyst which can also be easily prepared and separated, and mild reaction conditions, and it is also an environmentally friendly process for alcohol oxidation.
