1,2-Dichloroethane → Pentachlorofluorobenzene

Participants

Reaction Steps

A solution of 400 g (4.17 mol) of fluorobenzene in 2 l of 1,2-dichlorethane was admixed with 53.2 g (0.417 mol) of powdered AlCl3. 1394 g of chlorine gas were subsequently passed into the solution at 0-5° C. After the end of the reaction, the HCl formed was driven out at about 20-25° C. by means of a stream of nitrogen. The reaction solution was admixed with 200 ml of water while stirring vigorously, and the phases were then separated at 50° C.
