摘要：The invention provides a method of gas-phase catalytic oxidation, in particular, aproduction method of (meth)acrylic acid, which enables stable continuous operation ofgas-phase catalytic oxidation over a long term, maintaining high yield and suppressingincrease in pressure loss. In the method a fixed bed reactor is used, in which a treatingagent for removing organic substance and/or carbides, preferably a treating agent havingan adsorption capacity of at least 0.05% by mass, as measured by crotonaldehyde as anindicator of organic substance, is disposed on the upstream side of the gas-phaseoxidation catalyst layer in respect of the direction of the gas flow. It is desirable that atleast a part of the treating agent is exchanged at a frequency of at least once a year.
