Document Type and Number:
Japanese Patent JP5161570
Kind Code:
B2
Abstract:
[PROBLEMS] To provide a simpler method for producing a high-quality chlorinated aromatic hydrocarbon (e.g., cumylchloride), which can be used as a cationic polymerization initiator. [MEANS FOR SOLVING PROBLEMS] A chlorinated aromatic hydrocarbon can be produced by repeating both (a) the step of performing chlorination reaction by stirring an organic solution containing a compound represented by Ar(R 1 C=CH 2 ) n with an aqueous hydrochloric acid solution having a hydrochloric acid concentration of 30% by weight or higher and (b) the step of removing the water phase in part or whole from the reaction solution produced in the step (a), and then adding an aqueous hydrochloric acid solution having a hydrochloric acid concentration of 30% by weight or higher to the reaction solution, until the chlorination reaction rate of the compound reaches a predetermined level.
