ABSTRACT:
Maleic anhydride is produced by oxidizing a straight chain C.sub.4 hydrocarbon with oxygen in a stream comprising 25 to 60% by volume of the C.sub.4 hydrocarbon, 20 to 45% by volume of oxygen and optionally inert gases to produce a stream containing at least 21/2% by volume of maleic anhydride and condensing maleic anhydride substantially free from water from this stream.
