摘要： The present invention removes impurities inhibiting storage stability of (meth)acrylic acid or stability in polymerization of (meth)acrylic acid when (meth)acrylic acid is used as a raw material, to thereby stabilize (meth)acrylic acid. A total concentration of aromatic hydrocarbons each having 8 to 10 carbon atoms in a (meth)acrylic acid composition is controlled to less than 2 ppm. The (meth)acrylic acid composition can be obtained by crystallizing (meth)acrylic acid from a crude (meth)acrylic acid composition containing the aromatic hydrocarbons, sweating the crystallized (meth)acrylic acid, and separating the (meth)acrylic acid remained as a crystal after the sweating.
