A process for the preparation of cyclooctene which comprises irradiating 1,5-cyclooctadiene with light in the presence of a photodehydrogenation catalyst, acetone and an alcohol to partially hydrogenate the 1,5-cyclooctadiene.

Process for the preparation of cyclooctene

A process for the production of peracetic acid which comprises the steps of adding, to an inner solvent, acetaldehyde and at least one catalyst selected from the group consisting of strongly acidic carboxylic acids, strongly acidic phenols and nitric acid, and introducing oxygen gas or oxygencontaining gas into the resulting mixture while stirring the mixture and maintaining it at a temperature range of -5.degree. C to 50.degree. C.
