実験手順

To the same flask as used in Example 1 were added 340.51 g (1.0 mole) of 2,2'-methylenebis(6-tert-butyl-4-methylphenol), 72.06 g (1.0 mole) of acrylic acid, 400 g of n-heptane and 212.5 g (2.10 moles) of triethylamine. After replacing the air in the container with nitrogen, 200.7 g (0.70 mole) of phosphorus oxybromide was added dropwise with stirring. After completion of the dropwise addition, the reaction solution was kept at 80° C. for 1 hour. Thereafter, 500 g of water was added, and after cooling to room temperature, the deposited product was filtered off. The product obtained was washed with water until the washing became neutral to obtain 379.6 g of 2,2'-methylenebis(6-tert-butyl-4-methylphenol) monoacrylate as a white crystal. Melting point, 132°-134° C. Yield, 96%.
