    摘要： The object of the present invention is to provide, in the production of a useful oxidized organic compound by a catalytic gas-phase oxidation reaction on an industrial scale, a manufacturing method which, even when operation has been temporarily interrupted for periodic inspection or emergency shutdown, fully avoids the danger of an explosion due to reaction feedstock gases and the like remaining inside the reaction apparatus, and which, when operation is restarted, is able to shorten, relative to the prior art, the period required for the reaction to return to a stable steady state, and moreover which, after operation has restarted, does not undergo a decrease in yield, and allows a high yield to be stably maintained over a long period, whereby the production efficiency can be greatly increased. The disclosed invention is a method for manufacturing an oxidized organic compound which includes a step of forming an oxidized organic compound, in use of a fixed-bed reactor having a reaction tube packed with an oxide catalyst, by supplying at least one type of organic compound as a reaction feedstock gas and using a molecular oxygen-containing gas to carry out a catalytic gas-phase oxidation reaction; and a step of stopping the catalytic gas-phase oxidation reaction. In the manufacturing method, when stopping the catalytic gas-phase oxidation reaction, the supply of the reaction feedstock gas is stopped, after which an inert gas is supplied to the reactor, then a molecular oxygen-containing gas is supplied, subsequent to which the supply of the molecular oxygen-containing gas to the reactor is stopped.
