In chemical production processes, the separation of xylene and water is a common and critical unit operation. As an important organic solvent and chemical raw material, xylene is widely used in coatings, paints, pesticides, pharmaceuticals, and other industries. However, during…

Large quantities of heavy metal-containing sludge are generated every year by the electroplating, printed circuit board (PCB) manufacturing, and metal surface treatment industries. Among them, copper (Cu) and nickel (Ni) are two of the most valuable metals for recovery. Recovering…

During the production of antibiotics, vitamins, chiral pharmaceutical intermediates, alkaloids, and other pharmaceutical products, many active pharmaceutical ingredients (APIs) exhibit heat-sensitive characteristics—they are highly sensitive to temperature, pH value, and processing time. Prolonged exposure to unsuitable conditions can easily lead…

With the rapid development of global industrialization, industries such as coal chemical, petrochemical, pharmaceutical, and agrochemical have generated large volumes of high-concentration phenolic wastewater during their production processes. Due to its high toxicity, poor biodegradability, and significant environmental hazards, phenolic…

In the fields of fine chemicals and pharmaceutical intermediates production, cycloheptatriene, as a key raw material featuring unique aromaticity and an unsaturated cyclic structure, has a purity level that directly determines the success or failure of downstream high-end synthesis production…

Nickel is a recognized toxic heavy metal with bioaccumulative and persistent characteristics. Once released into water bodies or soil, it can enter the food chain and pose threats to ecosystems and human health. In industrial processes such as electroplating, metallurgy,…
