With the growing emphasis on green and sustainable practices, citrate esters—non-toxic, pollution-free, and biodegradable “green chemical products”—are seeing increasing demand across industries such as food, textiles, plastics, cosmetics, and detergents. However, in the production of citrate esters, efficiently and purifying…

In liquid-liquid extraction operations, emulsification is a common headache for many process engineers. When two immiscible liquids are mixed, factors such as surfactants, solid particulates, or excessive agitation can form a stable emulsion. At best, this makes phase separation difficult…

In fine chemical synthesis processes, extraction and washing (including water washing and alkali washing) are critical steps for removing solvents and byproduct salts from reaction mixtures. However, many companies still rely on traditional stirred tanks with static separation, which suffer…

High-purity manganese sulfate is the key raw material for nickel-cobalt-manganese (NCM) lithium-ion battery cathode precursors, with extremely stringent purity requirements. In particular, harmful impurities such as potassium, sodium, calcium, and magnesium must be below 5.0×10⁻⁵. During the purification of manganese…

Boric acid, as an essential basic chemical raw material, plays a critical role in sectors such as new energy batteries, high-end electronic glass and pharmaceutical intermediates. The purity of boric acid directly determines its value and performance in downstream applications.…

In the chemical, pharmaceutical, and pesticide industries, the treatment of high-salinity wastewater has long been a persistent challenge. The presence of organic contaminants in such wastewater not only lowers the purity of salt crystallization products—making resource recovery difficult—but also puts…
