Method for producing acrylic acid

Abstract

The present invention relates to a method for producing acrylic acid, and, more particularly, to a method for producing acrylic acid, which is capable of producing acrylic acid in a high yield in a short time in the case of producing acrylic acid using a supported catalyst having a specific composition when producing acrylic acid by oxidation of allyl alcohol, and capable of performing a reaction under neutral conditions without a base unlike the conventional technique in which a base must be used. In particular, the preparation method of the present invention has an advantage of enabling final recovery in the form of acrylic acid rather than acrylic acid salt, and thus can eliminate processes necessary in the conventional art, such as ion exchange after the acidification process required for converting acrylic acid salt into acrylic acid, thereby reducing the cost of the overall process.
