Reaction Steps
At the step (III) of Example 1, the reaction was carried out in the same manner as in Example 1 except that an aqueous solution was used in place of the N-methylpyrrolidone solution. As a result, the conversion of the α-hydroxyisobutyric acid amide as starting material was 98.6%, and the yield of methacrylic acid amide based on the converted starting material was 41.8 ol %. In addition, 32% of methacrylic acid, 10% of acetone, and 8% of methacrylonitrile were formed.
