Abstract

PURPOSE: The bromination of phenol is conducted in a heterogeneous system consisting of water and an organic solvent and the hydrogen chloride, by-product, is recovered by heating under refluxing, thereby producing high-purity tribromophenol in high yield.
CONSTITUTION: Phenol is brominate by using bromine chloride in a heterogeneous solvent system consisting of water and an organic solvent at 5W45°C. After addition of bromine chloride, the reaction mixture is heated under refluxing and hydrogen chloride is removed out of the system and recovered. The tribromophenol dissolving in the organic solvent is, without isolation, used for other purposes. When necessary, the tribromophenol in the organic solvent is reacted with an aqueous alkali to form its sodium salt. The heterogeneous solvent is composed of water containing more than 5 moles of hydrochloric acid per 1kg and an organic solvent which is less soluble in water and contains halogen.
EFFECT: Hydrogen chloride formed during the reaction is immediately absorbed in water and does not accumulate in the organic solvent in which the bromination occurrs, thereby preventing the reduction of reaction rate.
