Preparation method of dichlorotoluene nitride intermediate

The invention belongs to the technical field of preparation of pesticide intermediates, and particularly discloses a preparation method of a dichlorotoluene nitride intermediate. The preparation method comprises the following steps: fully reacting raw materials, a solvent and a nitration reagent to obtain a dichlorotoluene nitride intermediate, wherein the raw materials comprise any one of o-dichlorotoluene, m-dichlorotoluene and p-dichlorotoluene; the solvent is dichloroethane; the nitration reagent is concentrated nitric acid; the dichlorotoluene nitride intermediate is shown as a chemical formula 7 and a chemical formula 12. The preparation method has the advantages that the corrosion to reaction equipment is less, and the generation and discharge of waste acid and waste salt in the production process are greatly reduced.

A practical synthesis of 2,4-dichloro-3-methyl-6-nitrophenol

2,4-Dichloro-3-methyl-6-nitrophenol 2 was prepared by KOH/H2O hydrolysis of a product mixture obtained from chlorination of p-nitrotoluene in the presence of a phase transfer catalyst. A 95-99% yield of 2 based on 2,3,6-trichloro-4-nitrotoluene, 4 (major chlorination product) was achieved in >95% purity.
