Toluene - Preparation Method
Open Data Verified Data
The light gasoline obtained by atmospheric distillation (the initial distillation point is about 138 ° C), and the fraction of more than 65 ° C is cut off. The harmful impurities are removed by catalytic hydrogenation of molybdenum catalyst, and then reformed by platinum catalyst, extraction with diethylene glycol ether solvent, and then distillation, benzene, toluene, xylene and other products.
