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…

Naphthalenesulfonic acid series products are important fine chemical products for medicine, biology, dyes, etc. However, a large amount of wastewater is generated in the production of naphthalenesulfonic acid series products. The waste liquid has high COD, high chroma, strong acidity…

Excessive COD (chemical oxygen demand) in industrial wastewater has always been a difficult problem for environmental management. Traditional processes are inefficient and costly, but centrifugal extractor is becoming the “black technology” in the field of wastewater treatment with their technical…

In the context of the rapid development of the global new energy industry, lithium resources are known as “white oil”. As a by-product of lithium ore and salt lake lithium extraction process, lithium precipitation mother liquor has a residual lithium…

Centrifugal extractor, as an extraction equipment for continuous high-speed precision mixing and rapid centrifugal separation, has shown their strong application potential in many industries. With their efficient mixing and separation capabilities, as well as their adaptability to different material characteristics,…

In the pharmaceutical production process, the extraction and purification of intermediates is a crucial link. These intermediates usually have complex chemical structures and high value, so there are extremely strict requirements for their extraction methods. Extraction separation is a key…
