Pentabromophenol → o-(Pentabromphenoxymethyl)-benzoic acid-(pentabromophenyl) ester

Participants

Reaction Steps

In a two-liter flask, 5.6 of potassium hydroxide was dissolved at 75° C in 800 ml of methyl glycol; then 48.9 g (= 0.1 mole) of pentabromphenol was stirred in. To this phenolate solution, at 75° C, 64.15 g was added of the o-chloromethylbenzoic acid pentabromophenyl ester, prepared as in Example 9a, and the mixture was heated with stirring to ebullition. It was refluxed for an hour, then cooled, and the solids were isolated and worked up as described in the preceding examples.
