The optimum reaction conditions were: at present of acetic anhydride, a stoichiometric quantity of nitric acid, at room temperature for 40 minutes. Nitration of chlorobenzene gave a,50% yield of mononitro compounds, and an ortho-para isomer ratio 0.20 in product distribution of chlorobenzene mononitration.
结果表明：硅钨酸催化性能较好，催化剂载体以纳米二氧化硅最好，反应条件中醋酸酐用量是主要影响因素；SiW_(12)O_(40)~(4-)／纳米SiO_2催化剂具有强对位选择性：在醋酸酐存在下，氯苯与等当量的硝酸室温下反应40分钟，氯苯一硝化产物中邻／对硝基氯苯异构体的质量比达0.2，产率可达50％。
