At present, the commonly used methods for treating nickel-containing wastewater are: chemical precipitation (using hydroxide or sulfide as precipitant), electrolysis, ion exchange, adsorption and oxidation-reduction. Although the above methods are effective in removing nickel ions, they all face problems such…

Dichloromethane (DCM) is the core solvent for the extraction of pharmaceutical intermediates. It has the advantages of strong solubility and moderate boiling point. However, the traditional process generally has problems such as high solvent residue (>500ppm), low separation efficiency (single-stage…

The working principle and performance of the centrifugal extractor are fundamentally different from the operating principle of the reactor. When choosing equipment, you should choose the appropriate extraction equipment according to the specific extraction needs. When choosing equipment, you should…

In the field of fine chemicals and pharmaceuticals, 2-Methylfuran is an important organic solvent and intermediate, and its production process often faces the problem of efficient separation from the aqueous phase. The traditional static stratification method has problems such as…

Vanadium is a silvery white metal with a high melting point. It is often called a refractory metal along with niobium, tantalum, tungsten and molybdenum. Vanadium metal is ductile and hard. With the continuous research of technology on vanadium metal,…

As a hazardous chemical process that is subject to key supervision, nitration reaction has significant safety hazards. Nitrating agents are strong oxidants that easily generate a lot of heat during the reaction, which may lead to explosion accidents if not…
