Détail du produit

Dichlorométhane, an organic compound, is a colorless transparent liquid with a pungent odor similar to that of ether. Slightly soluble in water, soluble in ethanol and ether, under the usual conditions of use is a non-combustible low boiling point solvent, its vapor in high temperature air becomes a high concentration, it will generate a weak burning mixture of gases, commonly used to replace flammable petroleum ether, ether and so on.

Application

1. Industrial solvent: DCM is widely used in industry as a polar organic solvent. It can dissolve and dilute many organic compounds, such as paints, colles, resins, adhesives and chemical raw materials. Dichloromethane has important applications in dye, leather, metal cleaning, electronic device cleaning and other industries.

2. Pharmaceutical industry: chemical dichloromethane is a commonly used solvent and extraction agent, widely used in pharmaceutical preparations, synthetic drugs and natural drugs extraction and purification process.

3. Chemical synthesis: dichloromethane is an important reagent in organic chemical synthesis. Il peut être utilisé comme solvant, dehydrating agent and reaction medium in chlorination reaction to help accelerate the reaction speed and increase the yield.

4. Gas chromatography-Mass spectrometry (GC-MS) : Methylene chloride is a commonly used extraction agent and solvent in gas chromatography-mass spectrometry. It can help separate and detect compounds in complex mixtures for use in chemical analysis and sample pretreatment in mass spectrometers.

5. Pesticide and fertilizer production: dichloromethane, as an intermediate and reaction solvent, can be used in the manufacturing process of pesticides and fertilizers.
