The nitration of halobenzenes (chlorobenzene, bromobenzene and iodobenzene) was carried out using sulphated zirconia (SO42-/ZrO2) as catalyst and stoichiometric quantities of nitric acid and acetic anhydride in CCl4 medium at room temperature, 50 and 70 degrees C. The isolated yield of the nitrated product after vacuum distillation was found to be nearly 99% for all the halobenzenes. The order of selectivity to para-isomer was found to be chlorobenzene > bromobenzene > iodobenzene. The catalyst can be recycled at least five times with little decrease in its activity.
