Benzoic Acid → HCID 571439, compound

Participants

Reaction Steps

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), 122.12 g (1.0 mole) of benzoic acid, 500 g of toluene and 242.86 g (2.4 moles) of triethylamine. After replacing the air in the container with nitrogen, 229.15 g (1.2 moles) of o-toluenesulfonyl chloride was added dropwise with stirring. After completion of the dropwise addition, temperature maintenance and after-treatment were carried out in the same manner as in Example 3 to obtain 426.83 g of a white crystalline 2,2'-methylenebis(6-tert-butyl-4-methylphenol) monobenzoate having a melting point of 149° to 151° C. Yield, 96%.
