ABSTRACT:
A process for the liquid phase nuclear chlorination of benzenes which uses a novel manganese chloride catalyst in an iron-free reaction environment. The manganese chloride catalyst provides a dichlorobenzene product having a higher ratio of orthodichlorobenzene to paradichlorobenzene than is obtained with conventional commercial liquid phase chlorination catalysts.
