General Description

(2,4-dichloro-5-isopropoxyphenyl)hydrazine is a chemical compound with the molecular formula C9H12Cl2N2O. It is a hydrazine derivative, which means it contains a nitrogen-nitrogen double bond. (2,4-dichloro-5-isopropoxyphenyl)hydrazine is most commonly used as a pesticide and herbicide, particularly in the control of broadleaf weeds and woody plants. It works by disrupting the process of photosynthesis in the target plants, eventually leading to their death. Due to its potential toxicity, care should be taken when handling and using (2,4-dichloro-5-isopropoxyphenyl)hydrazine, and it should only be used as directed by the manufacturer and in accordance with relevant safety regulations.

Preparation method of oxadiazon intermediate 2, 4-dichloro-5-isopropoxyphenylhydrazine

The invention provides a preparation method of a herbicide oxadiazon intermediate 2, 4-dichloro-5-isopropoxy phenylhydrazine, which comprises the following steps: by taking a toluene solution of 2, 4-dichloro-5-isopropoxy aniline as a raw material, stirring to form a salt under an acidic condition, reacting with cyanate at a certain temperature to generate urea, degrading and rearranging by Hofmann in an alkaline environment, filtering, after recovering a solvent at normal pressure, taking 2, 4-dichloro-5-isopropoxy phenylhydrazine as a raw material, adding chloroform for extraction, and obtaining a chloroform solution of the 2, 4-dichloro-5-isopropoxy phenylhydrazine which can be directly used for an acylation process to synthesize the oxadiazon key intermediate 2, 4-dichloro-5-isopropoxy phenylhydrazine. According to the method disclosed by the invention, a complicated tin recovery process caused by reduction of diazonium salt by stannous chloride in a traditional synthesis process is effectively avoided, and generation of a large amount of high-salt wastewater in a recovery section is avoided; on the other hand, alkalization operation is avoided, solid materials are not added, the labor intensity is greatly reduced, and the production efficiency is effectively improved.
