Manufacturer Good Price Methylene Chloride CAS:75-09-2

short description:

Methylene Chloride is a compound generated by two hydrogen atoms in methane molecules, and molecular CH2CL2.Methylene Chloride is colorless, transparent, heavier, and volatile liquid. It has a smell and sweetness similar to ether. It does not burn. Methylene Chloride is slightly soluble in water, and it dissolves with most commonly used organic solvents. It can also be dissolved in any proportion with other chlorine-containing solvents, ether, ethanol, and N-di metamimamamide. Methylene Chloride is difficult to dissolve in liquid ammonia at room temperature, which can be quickly dissolved in phenol, aldehyde, ketone, triathrin, tororine, cycamine, acetylcetate. The phase Chemicalbook is 1.3266 (20/4 ° C). The melting point -95.1 ° C. Boiling point 40 ° C. Fully low -boiling point solvents are often used to replace flammable petroleum ether, ether, etc., and can be used as local anesthesia, refrigerant and fire extinguishing agent. The spontaneous combustion point is 640 ° C. Decoction (20 ° C) 0.43MPa · s. The refractive index nd (20 ° C) 1.4244. Critical temperature is 237 ° C, and critical pressure is 6.0795MPa. HCL and traces of light are generated after thermal solution, and the water is heated for a long time to generate formaldehyde and HCL. Further chloride, CHCL3 and CCL4 can be obtained.

Description

Properties: Pure dichloromethane has no flash point, and a solvent mixture containing equal volume of dichloromethane and gasoline, solvent naphtha or toluene is not flammable. However, when dichloromethane is mixed with acetone or methanol Chemicalbook liquid at 10: 1 proportion mixing, the mixture has a flash point, steam and air to form an explosive mixture, explosion limit 6.2% ~ 15.0% (volume).

Synonyms

F30;F30(chlorocarbon);Freon 30;Freon30;HCC30;Khladon30;M-clean D;Metaclen.

Applications of Methylene Chloride

Methylene Chloride (DCM) has the advantages of strong solubility and low toxicity. It is used to manufacture safe movies and polycarbonate, and the rest is used as coating solvent, metal abandoning agent, gas smoke spray, polyurethane foaming agent, de -molding mold Damage, lacquer agent. Dichloromethane is a colorless liquid, which is used as a reaction medium in the pharmaceutical industry to prepare ammonia penicillin, hydroxycin and pioneecin, etc.; Organic synthetic extracting agents, polyurethane and other foam plastic production for foaming agents and metal cleaning agents. Dichloromethane is mainly used in the field of film production and pharmaceuticals in China. Among them, the consumption of film production accounts for 50%of the total consumption, medicine accounts for 20Chemicalbook%of the total consumption, the consumption of the cleaning agent and the chemical industry accounts for 20%of the total consumption, and other aspects account for 10%. Dichloromethane is also used in industrial refrigeration systems for refrigerant, but it is very harmful and can produce toxic light when contacting light fire or burning objects. In the case of humid air, hydrolyzed hydrogen chloride can be used to promote hydrogen chloride, and light can also promote hydrolysis and enhance the corrosive metal. Used for cooling of grain fumigation and low -voltage frozen and air -conditioning devices. In the production of polyether -type urinary alkane plastic, it is used as auxiliary foaming agent, as well as foaming agents for squeezing polymutra foam plastics. Dichloromethane is also used to make substances for dehydrated coffee. The coffee first cooks to dissolve the caffeine and floats on the surface, and then use dichloromethane to remove caffeine.
1. It is a non -combustible low -boiling dot solvent, which is used as acetate cellulose membrane, air -soluble and antibacterial, and solvents in vitamin production.
2. Digerine is a raw material produced by sterilizers azoxazole and mimozole, and it is also a good solvent.
3. In addition to organic synthetic synthesis, this product is also widely used as a acetate cellulose membrane, triax cellulose pump, petroleum dehydration, gas solids and antibiotics, vitamins, 甾 ethnic compounds, and metal surfaces, and metal surfaces Classes Check CHEMICALBOOK to elux and decapyles. In addition, it is also used for cold and low -voltage frozen and air -conditioning devices. In the production of polyether -type urinary alkane plastic, it is used as auxiliary foaming agent, as well as foaming agents for squeezing polychida foam plastics.
4. Extract solvent. If it is used to extract caffeine in coffee beans. It is also used as a solvent for hills, fragrant oil resin, etc. Pigyl diluted agent.
5. For solvent, it is also used for organic synthesis.
6. Solvent for resin and plastic industry. It is widely used in industries such as medicine, plastics and film.
7. Ethyl cellulose solvent. Fat and oil extraction agent. A substitutes for ether and petroleum ether.
