摘要
以固体酸ＴｉＯ２ＺｒＯ２／ＳＯ２－４为催化剂时，甲苯硝化的位置选择性，对位硝基甲苯与邻位硝基甲苯之比（Ｐ／Ｏ）可达１５６。探索了该催化剂的最佳制备条件，取得了令人满意的结果。
The selection of methylbenzene nitration was raised, the ratio between para and ortho nitromethylbenzene reaching up to 1.56, when the solid acid TiO 2 ZrO 2/SO 2- 4 was taken as the catalyst. The optimum conditions of preparing the catalyst were investigated with satisfactory results.
