실험 절차

To the same flask as used in Example 6 were added 340.51 g (1.0 mole) of 2,2'-methylenebis(6-tert-butyl-4-methylphenol), 151.18 g (1.0 mole) of cinnamic acid, 500 g of toluene and 118.65 g (1.5 moles) of pyridine. After replacing the air in the container with nitrogen, 286.43 g (1.5 moles) of p-toluenesulfonyl chloride was added little by little with stirring. After completion of the addition, temperature maintenance and after-treatment were carried out in the same manner as in Example 6, and the residue was recrytallized from toluene to obtain 404.8 g of a white crystalline 2,2'-methylenebis(6-tert-butyl-4-methylphenol) monocinnamoate having a melting point of 164° to 169° C. Yield, 86%.
