PROBLEM TO BE SOLVED: To provide an industrial method for producing a bromine compound having excellent quality as a flame retardant for plastics. A method for producing a bromine compound represented by the following general formula (2) by reacting a compound having an aliphatic unsaturated bond represented by the following general formula (1) with bromine: The reaction is carried out in the presence of a solvent inert to the reaction, and a substantial amount of the heat of reaction is removed outside the reaction system by the heat of vaporization of the solvent or bromine. (Wherein, Ar 1 and Ar 2 represent an aromatic hydrocarbon group or a saturated alicyclic hydrocarbon group; Y represents a group that binds Ar 1 and Ar 2 ; R 1 and R 2 represent an aliphatic group) R 3 and R 4 represent a hydrocarbon group having at least one unsaturated group. Represents a group in which the unsaturated group in R 1 and R 2 is saturated by a bromine atom, respectively. ) |
