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.

Abstract: (4683) STACKED BED TUBULAR REACTOR FOR MALEIC ANHYDRIDE 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 produce to maleic anhydride.
