Abstract

PURPOSE: To reduce the formation of chloro-substitution products in the bromination an organic compound, while the accumulation of HCl into an organic solvent and the lowering of reaction rate, by carrying out the bromication of the organic compound, especially an aromatic compound, with bromine chloride in a hetero- geneous solvent comprising water and an organic solvent.
CONSTITUTION: In the substitution bromination of an organic compound having H which can be substituted with bromine, using bromine chloride, a heterogeneous solvent of water and an organic solvent is used. In that case, by-produced HCl immediately dissolves into water and does not accumulate in the organic solvent, and the lowering of reaction rate becomes insignificant. Since the formation of chloro-substitution products of organic compounds reduces as the amount of HCl present in an aqueous layer increases, the presence of at least 5mole of HCl per kg of water at the time of the beginning of the reaction is preferable. Aromatic compounds are suitable as the organic compounds, and halides as the solvent.
USE: Flame retarders for synthetic resin use, medicines, agricultural chemicals, etc.
