<p>An apparatus for producing an α,β-unsaturated nitrile with the same number of carbon atoms as that of an olefin or t-butyl alcohol as the starting material by the reaction of either propylene or isobutylene or t-butyl alcohol with ammonia and an oxygen-containing gas, said apparatus being constituted of a reactor; a starting gas supplier provided horizontally at a lower part of the reactor and equipped with a plurality of starting gas blow nozzles on the lower surface thereof; and an oxygen-containing gas supplier provided beneath the starting gas supplier in parallel therewith and equipped with the same number of oxygen-containing gas blow pipes as that of the starting gas blow nozzles on the upper surface thereof in such a manner that each of said pipes faces each of said nozzles, wherein a relative distance between the pipe and the nozzle ranges from 25 to 300 mm and the pipes are arranged at a distance of 90 to 250 mm from each other with a relative density of distribution of 16 to 120 /m2 of the cross section of the reactor.</p> |
