Acetochlor, as a widely used organic compound pre-sprout herbicide, the post-treatment step in its production process is crucial to ensure product quality. In the production process of acetochlor, pickling, alkali washing and water washing are the key steps to remove impurities and by-products in the reaction solution, and the effective execution of these steps is directly related to the qualified rate and purity of the final product. In this process, the combined extraction centrifugal extractor plays an irreplaceable role by virtue of its unique advantages.

Four-level processing process detailed explanation:

First stage pickling: In this stage, an appropriate amount of acid is added to the reaction solution, which is then subjected to efficient pickling by a combined extraction centrifugal extractor. With its strong centrifugal force, the combined extraction centrifugal extractor can quickly and effectively remove alkaline impurities and some metal ions in the reaction liquid, which lays a good foundation for subsequent treatment.

Secondary alkali washing: After pickling the reaction liquid, and then after an appropriate amount of alkali treatment, the use of combined extraction centrifugal extractor for alkali washing. This step is designed to further remove acidic impurities and by-products generated by the reaction with the acid, ensuring the purity of the reaction solution. The efficient separation capability of the combined extraction centrifugal extractor makes the process faster and more thorough.

Three-stage washing: the reaction liquid is mixed with deionized water or pure water, and washed through the combined extraction centrifugal extractor. This step is designed to remove inorganic salts, unreacted raw materials, and water-soluble impurities introduced during the acid-base washing process. The application of the combined extraction centrifugal extractor makes the washing effect significantly improved, and provides a strong guarantee for the purification of acetochlor.

Level 4 washing (optional) : Depending on the specific requirements of the production process, a second washing treatment may be required. Similarly, the combined extraction centrifugal extractor plays a key role in this step, further increasing the purity of acetochlor through its efficient and continuous separation capability.

Advantages of combined extraction centrifugal extractor in acetochlor production:

Efficient separation: The combined extraction centrifugal extractor relies on its powerful centrifugal force to significantly improve the separation efficiency and shorten the processing time, thereby improving the overall production efficiency.

Overcoming the emulsification problem: For systems containing emulsification, the combined extraction centrifugal extracter has demonstrated excellent separation capabilities, effectively overcoming the shortcomings of traditional separation methods.

Continuous production: Supporting continuous production mode not only improves production efficiency, but also meets the needs of large-scale production and reduces production costs.

Energy saving and environmental protection: small footprint, low power consumption, less residual liquid, help to reduce production costs and reduce environmental pollution, in line with the requirements of modern industrial green development.

The combined extraction centrifugal extractor has obvious application advantages and value in the post-treatment stage of acetochlor production process. By reasonably controlling the technical conditions and optimizing the operation process, the efficient, energy-saving and environmentally friendly production of acetochlor can be achieved, and the sustainable development of the pesticide industry can be contributed.
