甲苯通氯气,经过反应生成混合氯甲苯,其中对氯甲苯约70～35％,邻氯甲苯约50～60％,间氯甲苯少量,以及未反应甲苯约为10～20％,和2—3％多氯化合物,通过分离得到纯度≥96％对氯甲苯,≥98％邻氯甲苯。由于氯化液组分复杂,故采用一般分离异构体固定相得不到满足,我们采用了国产 Toluene through the chlorine, after the reaction to generate mixed chlorine toluene, which p-chlorotoluene about 70 ~ 35%, o-chlorotoluene about 50 ~ 60%, m-chlorotoluene small, and unreacted toluene about 10 ~ 20%, and 2-3 % Of polychlorinated compounds obtained by separation of purity ≥ 96% of p-chlorotoluene, ≥ 98% o-chlorotoluene. Due to the complexity of the chlorination liquid components, so the general separation isomers are not satisfied with the stationary phase, we use a domestic
