| titleOfInvention | Method for producing (meth) acrylic anhydride |
| abstract | PROBLEM TO BE SOLVED: To provide a method for producing high-purity (meth) acrylic anhydride having a low chlorinated substance content. SOLUTION: A carbodiimide derivative represented by the following formula (1): R 1 -N = C = NR 2 (1) (where R 1 and R 2 are each independently an alkyl group, A cycloalkyl group, an alkenyl group, an aralkyl group, an aryl group, or an aminoalkyl group, wherein the aminoalkyl group may form a salt with an acid.) By reacting with (meth) acrylic acid, ) Acrylic anhydride is produced. As the carbodiimide derivative, dicyclohexylcarbodiimide is preferable. |
