Phenyl methacrylate

Phenyl methacrylate was synthesized according to the literature, and the NMR spectroscopy were consisted with the reported data[3]Yield 1.45g, 84percent; Clear oil, Example 29 General procedure: 0.226 g (2.4 mmol, manufactured by Kanto Chemical Co., Inc.) of phenol and a compound represented by formula (I) (R1 is CH3, R2 is CH(CH3)2) (0.413 g, 2.4 mmol) were sequentially added, and the reaction was carried out at 80 ° C. under stirring, Phenyl methacrylate was produced.The reaction results after 7 hours from the start of the reaction are shown in Table 1.(Step (B)) 696 g (7.4 mol) of phenol and 35 g (0.35 mol) of 98 mass percent 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 percent, and the contained methacrylic acid was 823 g.Example 28 Example 37 In a 200 mL glass vessel equipped with an air inlet, added were 9.2 grams (106 mmol) of methacrylic acid, 44.0 grams (205 mmol) of diphenyl carbonate, 2.4 grams (12 mmol) of magnesium methacrylate as a catalyst, 0.04 grams of phenol as a polymerization inhibitor, and 3.5 grams (21 mmol) of diphenyl ether as an internal standard substance. While air was being blown into the mixture at a rate of 10 mL/min, the mixture was heated and stirred to an internal temperature of 140° C. The time when the internal temperature had reached 140° C. was set at zero, and 6.8 grams (80 mmol) of methacrylic acid was continuously added at a rate of 0.113 g/min during a time frame of 3090 minutes. Also, 5.2 grams (60 mmol) of methacrylic acid was continuously added at a rate of 0.058 g/min during a time frame of 95185 minutes. The total amount of supplied methacrylic acid was 21.2 grams (246 mmol). The mixture was stirred for an elapsed heating time of 5.0 hours. As a result, the conversion rate of diphenyl carbonate in the reaction liquid was 99.0percent. The amount of produced phenyl methacrylate was 30.9 grams (190 mmol). The yield of phenyl methacrylate relative to diphenyl carbonate was 93percent. The amount of produced MAA adduct was 0.53 grams (2.1 mmol). The yield of MAA adduct relative to diphenyl carbonate was 1.04percent. The amount of produced PhOH adduct was 0.20 grams (0.8 mmol). The yield of PhOH adduct relative to diphenyl carbonate was 0.39percent. The amount of produced phenyl methacrylate dimer was 0.79 grams (2.4 mmol). The yield of phenyl methacrylate dimer relative to diphenyl carbonate was 2.38percent. The selectivity of phenyl methacrylate (the value obtained when the yield of phenyl methacrylate is divided by the conversion rate of diphenyl carbonate) was 94percent.In a 200 mL glass vessel equipped with an air inlet, added were 21.2 grams (246 mmol) of methacrylic acid, 44.0 grams (205 mmol) of diphenyl carbonate, 1.2 grams (6 mmol) of magnesium methacrylate as a catalyst, 0.006 grams of 1, 4-benzendiol and 0.006 grams of 4-benzoyloxy-2, 2, 6, 6-tetramethylpiperidine-N-oxyl as polymerization inhibitors, and 3.5 grams (21 mmol) of diphenyl ether as an internal standard substance. While air was being blown into the mixture at a rate of 10 mL/min, the mixture was heated to an internal temperature of 100° C. and stirred for 16 hours. As a result, the conversion rate of diphenyl carbonate was 28.2percent in the reaction liquid. The amount of produced phenyl methacrylate was 8.8 grams (54 mmol). The yield of phenyl methacrylate relative to diphenyl carbonate was 27percent. In addition, the selectivity of phenyl methacrylate (the value obtained when the yield of phenyl methacrylate is divided by the conversion rate of diphenyl carbonate)
