摘要

The liquid phase chlorination of diphenylmethane (DPM) to 4, 4′-dichlorodiphenylmethane (4, 4′-DCDPM) is investigated at 333K, under atmospheric pressure over a number of zeolite catalysts using sulfuryl chloride (SO2Cl2) as the chlorinating agent. The results obtained are compared with those over the conventional Lewis acid catalyst, AlCl3 as well as without any catalyst. Zeolite KL is found to be highly active and selective catalyst for the ...
