Reaction Steps

Maleic anhydride has been generally prepared by concentration and dehydration of an aqueous solution of maleic acid, which is obtained by absorbing in water, in an apparatus such as a scrubber, a gas containing maleic anhydride, formed by catalytic oxidation of benzene, or gaseous by-products containing maleic anhydride, formed during the production of phthalic anhydride by catalytic oxidation of o-xylene or naphthalene.
