Abstract
A process for producing unsaturated nitrile comprising a reaction step of subjecting hydrocarbon to a vapor phase catalytic ammoxidation reaction in a fluidized bed reactor to produce the corresponding unsaturated nitrile, wherein, in the reaction step, a powder is fed to a dense zone in the fluidized bed reactor using a carrier gas, and a ratio of a linear velocity LV1 of the carrier gas at a feed opening to feed the powder to the fluidized bed reactor to a linear velocity LV2 of a gas in the dense zone (LV1/LV2) is not less than 0.01 and not more than 1200.
