摘要：
An improved process for the manufacture of maleic anhydride by catalytic oxidation of n-butane in which the feed flow channel to the catalytic reactor contains an autoignition suppression agent containing acid sites or trivalent phosphorus as an ignition inhibiting component. The autoignition suppression agent may also be used in other gas/liquid containment envelopes for flammable mixtures of hydrocarbons and oxygen. A novel apparatus and method are disclosed for assessing the influence of system conditions on autoignition of hydrocarbon/oxygen mixtures.
