반응 단계
The same flask as used in Example 1 was charged with a mixture of 1281.36g (8.0 mol) of diethyl malonate, 4.58g (34 mmol) of potassium dihydrogen phosphate, and 1.95g (0.9 mmol) of 2,6-di-t-butyl-4-methylphenol. After raising the inner teperature to 130° C., 174.48g (0.8 mol) of triethylene glycol monomethacrylate (MA-30 sold by Nippon Nyukazai Co., Ltd.) was added dropwise over 1 hour. After the addition, the mixture was heated at 130° C. for 4 hours. 32.21g (0.7 mol) of ethanol was recovered during the reactio period. Then the mixture was filtered to remove potassium dihydrogen phosphate and evaporated to remove remaiing diethyl malonate. 252.48g (95.0 % of theory) of triethylene glycol ethoxymalonate methacrylate was obtained.
