METHOD FOR PRODUCING ACRYLIC ACID

Abstract

The present invention relates to a method for preparing acrylic acid, more specifically to a method for preparing acrylic acid under the neutral condition at high yield in a short time without using a base, which can be performed under the neutral condition without using the base, unlike the prior art in which base is essentially used, by producing acrylic acid using the supported catalyst having a specific composition when preparing acrylic acid by oxidation of allyl alcohol. Particularly, the preparation method of the present invention can recover acrylic acid rather than acrylic acid salt as a final product, and thus has an advantage that the overall process cost can be reduced by eliminating essential processes in the prior art, such as ion exchange after the acidification process required for the conversion of acrylic acid salt to acrylic acid.
