ABSTRACT:
A method of preparing para-chlorotoluene by the electrolytic chlorination of toluene in an aqueous solution of hydrogen chloride or a metal halide as an electrolyte by passing an electric current from a cathode to an anode, both of which are immersed in the electrolyte, in order to form an active chlorine species which then reacts with toluene to produce the desired para-toluene. The anode is made of a carbonaceous material having cyclodextrin or a derivative thereof bonded onto its surface. The toluene that is introduced into the aqueous solution of electrolyte is included as a clathrate compound within the cyclodextrin.
