Abstract: Maleic anhydride is prepared by a novel 2-step process. In the first step, butadiene is prepared from n-butane or n-butene or from a mixture of these and molecular oxygen in an undivided reaction zone of a tubular reactor. This process is carried out in the presence of a catalyst. In the second step, which is carried out in the downstream zone of the tubular reactor, maleic anhydride is obtained from the product of the first step, which may still contain starting materials besides the butadiene, and in the presence of a second catalyst.

Abstract: Maleic anhydride is made from n-butane or n-butene in a tubular reactor having an undivided reaction zone which contains two different catalysts-the first catalyst converts at least part of the n-butane or n-butene to butadiene and the second catalyst converts at least part of this product to maleic anhydride.
