    • A process for producing an alpha . beta -unsaturated nitrile from propylene, isobutylene or tert-butyl alcohol in an industrial fluidized reactor with the step of feeding methanol and an oxygen-containing gas in the course of the whole contact time of the reactor and reacting unreacted ammonia with the methanol and the oxygen-containing gas, which can reduce the amount of unreacted ammonia without lowering the yield of the nitrile; and an industrial process of conducting the above production in an industrial fluidized reactor having an inner diameter of 3 m or above and filled with a molybdenum-bismuth catalyst supported on silica, which can prevent the feed opening of a dispersing nozzle for the methanol from clogging with molybdenum oxides to attain constant reduction in the amount of unreacted ammonia. The former is a process of catalytically reacting propylene, isobutylene or tert-butyl alcohol with ammonia and an oxygen-containing gas at high temperature in a gas phase by the use of a fluidized bed catalyst to form an alpha . beta -unsaturated nitrile having the same number of carbon atoms as that of the starting propylene, isobutylene or tert-butyl alcohol, wherein methanol and an oxygen-containing gas are fed into the fluidized reactor at the positions corresponding to one-half to nine-tenths of the whole contact time from the point of feeding the starting materials through gas dispersing nozzles respectively and the fluidized reactor has at least one perforated structure having a throat area ratio of at least 60 % set above and/or below the gas dispersing nozzles; and the latter is a process of producing an alpha . beta -unsaturated nitrile as described above, wherein the methanol is fed together with steam through the same gas dispersing nozzle to thereby inhibit the catalyst from adhering to the dispersing nozzle and remove the catalyst adherent thereto.
    • 一种生产α的方法。 在工业流化反应器中,丙烯,异丁烯或叔丁醇的β-不饱和腈,在反应器的整个接触时间和甲醇和未反应的氨反应过程中进料甲醇和含氧气体的步骤 含氧气体,其可以在不降低腈的产率的情况下减少未反应的氨的量; 以及在内径为3μm以上的填充有二氧化硅的钼 - 铋催化剂的工业流化反应器中进行上述生产的工业方法,其能够防止用于甲醇的分散喷嘴的进料口堵塞 与钼氧化物一起达到未反应氨的量的恒定降低。 前者是通过使用流化床催化剂在丙烯,异丁烯或叔丁醇与氨和含氧气体在高温下催化反应形成α的方法。 具有与起始丙烯,异丁烯或叔丁醇相同碳原子数的β-不饱和腈,其中甲醇和含氧气体在对应于二分之一至九分之一的位置进料到流化反应器中, 从原料通过气体分散喷嘴分别供给点的整个接触时间的十分之一秒,并且流化反应器具有至少一个具有至少60%的喉部面积比设置在气体分散喷嘴上方和/或下方的穿孔结构; 后者是产生α的过程。 如上所述的β-不饱和腈,其中甲醇与蒸汽一起通过相同的气体分散喷嘴进料,从而抑制催化剂附着在分散喷嘴上并去除附着在其上的催化剂。
