Abstract
PURPOSE: To obtain the titled compound in high yield and purity, by photochlorinating the side chain of an aromatic compound having a lower alkyl group as the side chain in the presence of a lactam as a metallic component capturing agent capable of capturing impure metallic components present in the reaction system effectively without exerting a bad influence on the reaction.
CONSTITUTION: The side chain of an aromatic compound, e.g. p-xylene, having a lower alkyl group as the side chain is photochlorinated in the presence of a lactam, of the formula (R1 and R2 are H or lower alkyl; n is an integer 3W7), most effectively ε-caprolactam, in an amount of 5ppmW10%, preferably 100W 1,000ppm, based on the weight of the reaction solution as a metallic component capturing agent.
EFFECT: The light transmission to the reaction system is not prevented.
