Product detail


Molecular formula: CH2CL2

Molecular weight: 84.93

Physical and chemical properties:

colorless transparent volatile liquid, similar to the smell of ether and sweet.

Relative density: D4201.326Kg/L.

boiling point: 40.4 DEG C.

melting point: -96.7 degrees, the ignition point of 615 DEG C. Slightly soluble in water, soluble in ethanol, ethyl ether, toxic, narcotic stimulation. Dichloromethane and water hydrolysis reaction, dichloromethane containing commercial stabilizer, to prevent hydrolysis. Dichloromethane and high concentration oxygen will produce explosive mixture, but not flammable, is commonly used in industry of low toxicity, non flammable solvent and low boiling point.


Purpose


For non flammable solvent: metal cleaning, paint remover, metal degreasing agent, three cellulose acetate solvent; film, aerosol, antibiotics and vitamins in the production of solvent; foaming agent for foaming for the production of engineering plastics; flame retardant products; used to replace F11 and F12 use for the synthesis of products; fine chemical products.


Packaging, storage and transportation


Galvanized steel, black steel drum or tank sealed packaging container filling volume of dichloromethane, the 80%, can provide nitrogen protection for users with special requirements. Storage should be stored in a cool and dry place, the warehouse should be ventilated to avoid contact with high concentrations of oxygen or oxides, to avoid contact with water in order to prevent hydrolysis. The transport shall comply with the provisions of the People's Republic of China concerning the transport of dangerous chemicals by highways and railways.


Health and safety


Sichloromethane in the air explosion limit: 8.1 ~ 17.2%, belongs to combustible chemicals. High concentration, long time exposure easily cause dizziness, drowsiness, nausea, tinnitus or numbness of limbs, move to fresh air, the symptoms quickly restored, will not cause lasting damage. Splash into the eyes cause pain and irritation, long-term contact with the skin can cause dermatitis.
