摘要： In a process for producing a (meth)acrylic acid compound by catalytic vapor phase oxidation, the (meth)acrylic acid compound is produced constantly and efficiently by preventing the change in the composition of the raw material mixed gas, the abnormal temperature increase in the oxidation reactor and the deterioration of the catalytic activity or the useful catalyst life. In the process for producing (meth)acrolein or (meth)acrylic acid by the catalytic vapor phase oxidation reaction of propylene, propane or isobutylene in the oxidation reactor, the temperature of the raw material mixed gas introduced to the oxidation reactor is maintained to be at least the dew point temperature of the raw material mixed gas.

摘要： The invention provides a process for producing and/or purifying acrylic acid or methacrylic acid and an ester of these, wherein high-boiling heavy ingredients (high-boiling matters) discharged from individual step units are classified by the content therein of (meth)acrylic acid and/or of the dimer thereof and treated. According to the invention, even when high-boiling matters which have been discharged from distillation columns, high-boiling-matter cracking reactors, and the like in a plant for producing (meth)acrylic acid and/or an ester thereof and are alike in liquid nature are mixed with each other in the same tank, no polymer precipitation occurs. The handling and storage thereof are hence easy. Consequently, tanks can be united into one, and the process is extremely advantageous in reducing the construction cost and the area necessary for equipment.
