Procedure
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), 74.08 g (1.0 mole) of propionic acid, 500 g of toluene and 191.42 g (2.42 moles) of pyridine. After replacing the air in the container with nitrogen, 210.05 g (1.1 moles) of o-toluenesulfonyl chloride was added dropwise with stirring. After completion of the dropwise addition, the reaction solution was kept at 100° C. for 1 hour and then aftertreated in the same manner as in Example 2 to obtain 384.7 g of a white crystalline 2,2'-methylenebis(6-tert-butyl-4-methylphenol) monopropionate having a melting point of 108° to 110° C. Yield, 97%.
