Abstract:
1. An oxidized organic compound manufacturing method, comprising: 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, wherein 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 when an amount of carbon oxide present in the gases at an outlet of the reactor, excluding an amount of carbon oxide contained in the molecular oxygen containing gas supplied, is greater than 0ppm and not more than 1,000ppm.
