TBP is a commonly used organophosphorus compound, which is widely used as an organic solvent, antistatic agent, plasticizer, etc. The production of TBP usually involves chemical reaction and separation process. The extraction tank is used to extract the target product from the mixture, usually by mixing the extractant with the raw material and interacting with the target product, and then extracting it through the separation process. Therefore, the definition of the extraction tank for tributylphosphine production is an industrial equipment used to produce TBP, which is mainly used for separation operation in the TBP synthesis process to extract the target product TBP from the reaction mixture.
