Procedure

It is known that maleic anhydride is prepared by catalytic vapor-phase oxidation of benzene, naphthenes, butenes and butane. It is also obtained as a by-product in the preparation of phthalic anhydride by oxidation of o-xylene or naphthalene. It is isolated from the crude maleic anhydride, usually by fractional distillation, in which it is obtained in the form of white, virtually pure maleic anhydride.
