The synthesis of intermediates is generally carried out in a reactor, and the generated intermediates need to be separated and purified, usually achieved using extraction technology. Chloroform extraction of pesticide intermediates is a common operation unit in chemical enterprises. Traditional extraction processes generally use distillation columns, a method that is complex, has low extraction efficiency, and is energy-consuming.

Therefore, with the deeper social division of labor and progress in production technology, most enterprises have begun to carry out technical reforms and adopt more efficient processes for operations. Among these, solvent extraction has become the main operation unit in the extraction section of the chemical field. Solvent extraction involves selecting a suitable extractant, mixing the raw solution with the extractant, transferring the organic phase in the raw solution to the extractant, and then separating the two phases to extract the organic phase. This method is simple to operate, has high extraction efficiency, uses cheap and readily available extractants, and allows the extractant to be recycled, effectively saving overall input costs.
