The solid catalysts of SO4 2-/TiO2, SO4 2-/TiO2-ZrO2, SO4 2-/WO3-ZrO2, and SO4 2-/MoO3-ZrO2 have been prepared and regioselectiveties of chlorobenzene minonitration on these catalysts were investigated. When the reaction was carried out at 30 C for 30 min, SO4 2-/TiO2-ZrO2(1:1) by a calcination step for 3 h at 550 C enhanced the para-selectivity of chlorobenzene nitration by using nitric acid as nitrating agent, up to an ortho-para isomer ratio 0.17 in product distribution of chlorobenzene mono- nitration, and the yield of chlorobenzene mononitration was 55%. The catalysts could be reutilized for four times with a little decrease in activity.
