| titleOfInvention | Process for producing (meth)acrolein or (meth)acrylic acid |
| abstract | There is provided a process for producing (meth)acrolein or (meth)acrylic acid which is capable of avoiding stoppage of operation of a plant for production thereof as a whole due to failure of a low-boiling fraction separation step in the process and ensuring a continuous stable operation of the plant, and has excellent economical aspects. The process for producing (meth)acrolein or (meth)acrylic acid according to the present invention sequentially comprises an oxidation reaction step of subjecting a raw gas to gas-phase catalytic oxidation; a reaction gas cooling step of cooling the resultant reaction gas; a low-boiling fraction separation step of separating low-boiling components from the reaction product; a purification step of separating and removing high-boiling components from the reaction product; and a high-boiling fraction decomposition step of decomposing the high-boiling components contained in a bottom liquid obtained from the purification step, said low-boiling fraction separation step comprising a plurality of low-boiling fraction separation steps which are disposed in parallel with each other and operated at the same time. |
