Dichloromethane is often used as an extractant in extraction operations in the chemical industry. However, due to different extraction processes, customers should consider the extraction process when choosing extraction equipment. The main method for extracting organic matter from water with…
Treatment of phenolic wastewater is a pretreatment operation, which is a pretreatment before wastewater treatment. Because phenol-containing wastewater generally has a high concentration, high organic matter content, and high COD, it is very troublesome and costly to discharge it directly…
The commonly used method for extracting p-hydroxybenzoic acid is solvent extraction, which is also an extraction process with relatively high extraction efficiency. P-hydroxybenzoic acid is a very important organic synthesis raw material with a wide range of applications. Therefore, companies…
The extraction of metallic indium is a common operation unit in the field of hydrometallurgy, and there are many extraction methods. A large number of case data and experiments have shown that the use of solvent extraction method to extract…
In the production process of chemical plants, a lot of chemicals are needed, and the water washing section during product production will produce a large amount of organic wastewater, common ones include phenol-containing wastewater, DMF wastewater, DMAC wastewater, butyric acid…
N-Butylthiophosphoric triamide, abbreviated as NBPT, is a nitrogen fertilizer slow-release agent, which is used to improve the utilization rate of nitrogen fertilizer. In the production process of NBPT, the traditional process is to use dichloromethane as the solvent, trichlorothiophosphorus and…
