Toluene extraction is a liquid-liquid extraction technology that uses toluene as an organic solvent to separate, enrich or purify specific target substances from aqueous solutions. In the fields of pharmaceutical intermediates, pesticide technical and fine chemicals, toluene extraction is a…

In the production process of phenolic resin, phenol needs to be added for batching, and water vapor needs to be used to pass through the phenolic resin to remove excess phenol and purify the product in the later stage, which…

In core fields such as medicine, pesticides, and fine chemicals, dichloromethane has become an indispensable extraction solvent due to its excellent solubility. However, when dealing with dichloromethane systems, traditional extraction equipment often faces pain points such as low separation efficiency,…

Solvent extraction method for treating DMAC wastewater is to utilize the high selectivity and high solubility of the extractant to DMAC to transfer DMAC from the aqueous phase to the organic phase to achieve separation and enrichment. Centrifugal extractor is…

Separate, concentrate or purify phosphoric acid from a solution containing phosphoric acid (usually wet-process phosphoric acid or a leachate containing phosphoric acid), remove impurities (such as metal ions Mg²⁺, Fe³⁺, Al³⁺, Ca²⁺, SO₄²⁻, F⁻, etc.), and produce high-purity phosphoric acid…

With the explosive growth of the new energy vehicle industry, the demand for recycling of ternary lithium batteries has surged. How to efficiently extract high-value metals such as lithium, nickel, and cobalt has become the focus of the industry. Centrifugal…
