Method for producing (meth)acrylic anhydride, method for storing (meth)acrylic anhydride, and method for producing (meth)acrylate |
摘要 |
It is an object of the present invention to provide a method for producing (meth)acrylic anhydride that provides high yield and high efficiency and can suppress side reactions, in a method for reacting (meth)acrylic acid with a fatty acid anhydride to produce (meth)acrylic anhydride. The method for producing (meth)acrylic anhydride according to the present invention is a method for producing (meth)acrylic anhydride, including reacting a fatty acid anhydride with (meth)acrylic acid to produce (meth)acrylic anhydride, while extracting a fatty acid produced as a by-product, wherein the reaction is performed, while adjustment is performed so that a molar ratio of the (meth)acrylic acid to the (meth)acrylic anhydride in a reaction liquid is 0.3 or more.
