Centrifugal extractor, as a new, fast and efficient liquid-liquid mixing and separation equipment, has been widely used in chemical industry. Especially in the extraction of sulfoxide compounds, the combined extraction centrifugal extractor has become an indispensable tool for chemical enterprises with its characteristics of high efficiency, continuity and easy operation.

Sulfoxide compounds are a kind of important organic compounds, widely used in medicine, pesticides, fine chemical industry and other fields. Because of their unique chemical properties and wide applications, the extraction and purification of sulfoxide compounds has been the focus of chemical enterprises. Although the traditional extraction method can meet the demand of extraction and purification to a certain extent, there are some problems such as low separation efficiency, complex operation and limited processing capacity. The emergence of combined extraction centrifugal extractor has effectively solved these problems.

The working principle of the combined extraction centrifugal extractor is based on the principle of centrifugal force and density difference. When two non-phase solutions (such as the solution containing sulfolides and the extractant) are mixed into the centrifugal extractor, they are rapidly separated under the centrifugal force generated by the high-speed rotation of the drum due to their different densities. Heavy phase liquid (such as water phase), due to its greater density, will be thrown to the drum wall further away, forming the outer liquid ring; The light phase liquid (such as the organic phase) is located in the inner layer near the center because it is less dense. In this way, the two liquids form two annular flow areas inside the drum, achieving effective extraction and separation.

In the process of extracting sulfoxide compounds, the advantages of the combined extraction centrifugal extractor are mainly reflected in the following aspects:

Efficient mixing and separation: the centrifugal extractors cut the droplets through the high-speed rotating drum, so that the two phases are fully mixed and mass transfer, and the two liquids that are not mutually soluble form obvious stratification under the action of centrifugal force in the drum, so as to realize the purpose of transferring the material from one liquid phase to another liquid phase. This highly efficient separation method not only improves the extraction efficiency of sulfoxide compounds, but also reduces energy consumption and chemical consumption.

Continuous production: centrifugal extractor can be used in a single unit, or multi-stage series to achieve countercurrent extraction. This continuous production method not only improves the production efficiency, but also ensures the stability and consistency of product quality.

Easy operation: The operation of the centrifugal extractor is simple and easy, and the parameters such as speed, flow ratio and mixing strength can be changed as needed to adapt to the chemical production process of different scales and process requirements.

Environmentally sustainable: The centrifugal extractor produces less waste during the extraction process and is easy to handle and recycle. This is in line with the current chemical industry requirements for environmental protection and sustainable development.

The application cases of the combined extraction centrifugal extractor in the extraction of sulfoxides are numerous. For example, in the process of drug manufacturing, centrifugal extractors can be used to separate and purify sulfoxide compounds in drug ingredients, remove unwanted impurities and solvents, and improve the purity and yield efficiency of drugs; In the field of fine chemicals, centrifugal extractors can be used for the separation and purification of acids, bases, salts and other chemicals in production, providing a high level of purity and yield assurance; In the petrochemical process, the centrifugal extractor can separate and recover the solvent, oil, chemical reaction products, etc., to improve the efficiency of resource utilization and environmental friendliness.

In summary, the combined extraction centrifugal extracter has significant advantages and broad application prospects in the extraction of sulfoxide compounds in the chemical industry. With the continuous progress of technology and the continuous optimization of the process, the centrifugal extractor will play a more important role in the chemical industry and contribute more to the sustainable development of chemical enterprises.
