In the fields of fine chemicals, pharmaceutical intermediates, pesticide raw materials, and oil-based material purification, water washing, alkali washing, and acid washing are critical processes that directly determine product purity and yield. For many years, traditional reactor static settling processes…

In the production fields of fine chemicals, pharmaceuticals, coatings, and new energy materials, glycol ether organic solvents (such as ethylene glycol ethers, propylene glycol ethers, isopropyl ether, and isopropanol) are widely used. However, these production processes generate large amounts of…

During the lithium extraction process from ores such as spodumene and lepidolite, lithium precipitation mother liquor is often regarded as “waste liquid” or a low-value by-product. However, hidden in this seemingly ordinary alkaline mother liquor are two rare alkali metals…

In the modern chemical industry, efficient and environmentally friendly material separation and purification technologies are key drivers of industrial upgrading. Especially for the recycling and reuse of important organic solvents such as benzene and xylene, the traditional batch reactor operation…

In chemical production, wastewater treatment, and salt lake resource development, the precise removal of chloride ions has always been a key factor in determining product quality and environmental compliance. Chloride-containing solutions are often characterized by strong corrosiveness, a high tendency…

In the synthesis and purification processes of pharmaceutical intermediates, manufacturers generally face three major technical challenges: difficulty in breaking emulsified layers, resulting in slow phase separation; significant evaporation of organic solvents, causing environmental and cost pressures; and degradation or loss…
