  In a process for producing (meth)acrylic acid comprising contacting a reaction gas containing (meth)acrylic acid obtained by gas-phase catalytic oxidation with an absorbent solvent to prepare a (meth)acrylic acid solution; and introducing the (meth)acrylic acid solution into a distillation column to purify (meth)acrylic acid, after a dissolved oxygen concentration in the (meth)acrylic acid solution to be introduced into the distillation column is adjusted to not less than 12 ppm by weight, the (meth)acrylic acid solution is fed to the distillation column. In addition, upon an azeotropic dehydration distillation step, a phenol-based polymerization inhibitor is fed to an azeotropic dehydration distillation column from a position not lower than a raw material feed stage thereof, and a copper-based polymerization inhibitor is fed to the azeotropic dehydration distillation column from a position lower than the raw material feed stage. According these methods, the production of polymers of (meth)acrylic acid and polymerization clogging in the distillation column are prevented, so that it is possible to stably purify (meth)acrylic acid by distillation for a long period of time.

  在生产（甲基）丙烯酸的过程中，包括将通过气相催化氧化获得的含有（甲基）丙烯酸的反应气体与吸收溶剂接触，制备（甲基）丙烯酸溶液；并将（甲基）丙烯酸溶液引入蒸馏塔以纯化（甲基）丙烯酸，在将要引入蒸馏塔的（甲基）丙烯酸溶液中溶解氧浓度调整至不低于12 ppm重量后，将（甲基）丙烯酸溶液送入蒸馏塔。此外，在共沸脱水蒸馏步骤中，从不低于原料进料阶段的位置向共沸脱水蒸馏塔中加入苯酚类聚合抑制剂，并从低于原料进料阶段的位置向共沸脱水蒸馏塔中加入铜基聚合抑制剂。通过这些方法，可以防止（甲基）丙烯酸的聚合物生成和蒸馏塔中的聚合物堵塞，从而可以长时间稳定地通过蒸馏纯化（甲基）丙烯酸。
