| titleOfInvention | Method for producing (meth)acrylic acid |
| abstract | The present invention provides a method for suppressing an undesirable polymerization reaction of (meth)acrylic acid in a purification step for producing (meth)acrylic acid and for avoiding troubles due to clogging of devices or the like, to thereby attain a stable continuous operation. The present invention provides a method for producing (meth)acrylic acid comprising: distilling a water-containing liquid of (meth)acrylic acid containing (meth)acrylic acid and water by using a distillation column in the presence of an azeotropic solvent boiling together with at least water to remove water from the water-containing liquid of (meth)acrylic acid through azeotropy with the azeotropic solvent, in which the water-containing liquid of (meth)acrylic acid is distilled in the presence of the azeotropic solvent after distillation by the azeotropic solvent is carried out in the distillation column. |
