| titleOfInvention | A kind of production technique of high-purity 2,4-dichlorotoluene |
| abstract | The invention relates to the technical field of compound synthesis and purification, in particular to a production process of high-purity 2,4-dichlorotoluene. The method comprises the following steps: adopting p-chlorotoluene and chlorine to catalyze synthesis of 2,4-dichlorotoluene, and obtaining high-purity 2,4-dichlorotoluene after alkali washing, rectification, recovery of fractions, and purification and crystallization. The invention solves the problems of low yield, low purity and difficult purification of 2,4-dichlorotoluene in the prior art, and the prepared 2,4-dichlorotoluene has high yield, high purity and recyclable materials. advantage. |
