Reaction Conditions:
with sulfuric acid at 80; for 8 h;Product distribution / selectivity;
Steps:
19.B
(Step (B)) 696 g (7.4 mol) of phenol and 35 g (0.35 mol) of 98 mass % sulfuric acid were added to the 3 L flask containing the above reaction liquid, and the mixture was heated to 80°C, with air bubbled, and then reacted for 8 hours. The methacrylic anhydride disappeared completely. The yield of phenyl methacrylate based on the methacrylic anhydride (calculated by dividing the number of moles of the phenyl methacrylate at the completion of the reaction by the number of moles of the methacrylic anhydride and multiplying the result by 100) at this time was 99.1 %, and the contained methacrylic acid was 823 g.
