Abstract

PURPOSE: In preparing brominated diphenylethers by bromination of diphenyl ether, the product is purified by adding an inorg. acid solution to the reaction solution to effect simultaneous crystallization and treatment or by treating the previously crystallized product with an inorg. acid solution.
