| titleOfInvention | Method for preparing o-chlorotoluene |
| abstract | The invention discloses a method for preparing o-chlorotoluene. The method comprises the following steps: adding a raw material toluene and a FeCl3-loaded macroporous metal silica gel catalyst into a reaction kettle; introducing chlorine into the reaction kettle for a liquid-phase ring chlorination reaction between the toluene and chlorine; after the reaction is complete, aerating to remove residual chlorine and hydrogen chloride gas in the reaction liquid; rectifying the reaction liquid to separate out unreacted toluene and a little dichlorotoluene to obtain mixed chlorotoluene; and then, separating high-purity p-chlorotoluene from the mixed chlorotoluene by using a melt crystallization process. According to the method disclosed by the invention, the FeCl3-loaded macroporous metal silica gel catalyst is adopted for catalyzing the selective chlorination of toluene, the reaction is fast, the catalytic activity is high, the o-chlorotoluene selectivity is good, the requirements for the technological conditions are low, the catalyst consumption is low, the catalyst has high activity and can be recycled, and the method has a good industrial prospect. |
