5-Hydroxymethylfurfural (HMF) is a furan compound synthesized by the Maillard reaction or by catalytic dehydration of fructose under acidic conditions. In terms of industrial applications, HMF is widely used to synthesize various chemicals such as monomers, fuels, additives, surfactants, and…

In chemical industry, the treatment of waste liquid generated during the production and purification of phosphoric acid has always been an important environmental issue. Especially in the wet phosphoric acid process, due to the high impurity content in the raw…

In many fields such as chemistry, medicine, and food, the processing technology of extraction liquids plays an important role. In actual production, we often encounter situations where we need to perform multi-stage extraction on the extraction liquids. This article will…

Current Status of NMP Wastewater Treatment NMP can be miscible with water in any ratio, has high boiling point, flash point and strong solubility, so it is not easy to separate and recover directly from NMP aqueous solution. Its recovery…

Liquid liquid extraction/solvent extraction is a technique for separating substances based on the different solubility or partition coefficients of substances in two immiscible or slightly soluble solvents. Here are some key information about solvent extraction: Liquid liquid extraction is an…

In the field of organic synthesis, water washing, as a basic and crucial process, runs through the production process of many products. Its important value lies in effectively removing the residual acid, alkali, salt and other water-soluble impurities in the…
