The purification method of methylene chloride
Methylene chloride(CAS 75-09-2 DCM) has broad-spectrum solvency, low boiling point, relatively low toxicity and relatively best reaction inertness, making it the most frequently used organic solvent in organic synthesis. As a solvent, its status is almost equivalent to that of water in
Preparation and precautions of methylene chloride
Method of making: 1. Natural gas chlorination method Natural gas reacts with chlorine gas, and after absorbing hydrogen chloride by water to produce hydrochloric acid, the residual trace hydrogen chloride is removed with lye, and then dried, compressed, condensed and distilled to obtain the finished product, wherein chlorine gas 100% 4000, natural gas (standard condition Bottom), methane content 97%, liquid caustic soda 100% 274.
Effects and chemical properties of dichloromethane
Dichloromethane has the advantages of strong solubility and low toxicity, and is widely used in the manufacture of safety film films and polycarbonates, and the rest are used as paint solvents, metal degreasers, gas smoke
Application and danger of dichloromethane
Solvent is the most important use of dichloromethane. Dichloromethane has broad-spectrum solvency, low boiling point, relatively low toxicity and relatively best reaction inertness, making it the most frequently used organic solvent in organic synthesis. Its status
Methylene chloride wastewater treatment method
methylene chloride, with the molecular formula CH2Cl2, is a colorless and transparent liquid with the advantages of strong solubility and low toxicity. It is slightly soluble in water and is a non-flammable low-boiling solvent.
Partial methods of dichloromethane waste gas treatment
Efficient treatment of dichloromethane waste gas is essential to prevent its release into the environment, where it can contribute to air…
