Dichloromethane
Physical and chemical properties of dichloromethane
Appearance and Properties: Colorless transparent liquid with aromatic odor.
Melting point (°C): -96.7
Boiling point (°C): 39.8
Relative density (water=1): 1.33
Relative vapor density (air=1): 2.93
Saturated vapor pressure (kPa): 30.55 (10°C)
Combustion heat (kJ/mol): 604.9
Dichloromethane sds Solubility: slightly soluble in water, soluble in ethanol and ether
Dichloromethane sds Hazardous Properties
Poisonous phosgene can be produced on contact with open flames or hot objects. In case of humid air, it can be hydrolyzed to generate a small amount of hydrogen chloride, and light can also promote hydrolysis and increase the corrosiveness to metals.
Dichloromethane sds emergency measures
Skin Contact: Remove contaminated clothing and rinse skin thoroughly with soap and water.
Eye Contact: Lift the eyelids and flush with running water or normal saline. seek medical attention.
Inhalation: Quickly leave the scene to fresh air. Keep the airway open. If breathing is difficult, give oxygen. If breathing stops, give artificial respiration immediately. seek medical attention.
Ingestion: Drink enough warm water to induce vomiting. seek medical attention.
Dichloromethane sds leakage treatment
Quickly evacuate personnel from the leaked contaminated area to a safe area, isolate them, and strictly restrict access. Cut off the source of ignition. It is recommended that emergency personnel wear self-contained positive pressure breathing apparatus and protective clothing. Cut off sources of leaks as much as possible. Prevent flow into restricted spaces such as sewers and flood drains. Small spills: Absorb or absorb with sand or other non-combustible materials. Large spills: Construct dikes or dig pits for containment. Cover with foam to reduce vapor hazards. Transfer it to a tanker or a special collector with a pump, and recycle it or transport it to a waste disposal site for disposal.
Dichloromethane sds Storage and Transportation Instructions
Store in a cool, ventilated warehouse. Keep away from fire and heat sources. The storage temperature should not exceed 30℃, and the relative humidity should not exceed 80%. Keep container tightly closed. It should be stored separately from alkali metals and edible chemicals, and should not be stored together. Equipped with the appropriate variety and quantity of fire equipment. Storage areas should be equipped with emergency release equipment and suitable containment materials.
Before transporting dichloromethane, check whether the packaging container is complete and sealed, and ensure that the container does not leak, collapse, fall or damage during transportation. It is strictly forbidden to mix with acids, oxidants, food and food additives. During transportation, the transport vehicle shall be equipped with the corresponding variety and quantity of fire fighting equipment and leakage emergency treatment equipment. During transportation, it should be protected from exposure to sunlight, rain, and high temperature. When transporting by road, follow the prescribed route.
Dichloromethane sds fire-fighting measures
Hazardous combustion products: carbon monoxide, carbon dioxide, hydrogen chloride, phosgene.
Dichloromethane sds fire extinguishing method: Firefighters must wear gas masks and full-body firefighting suits to put out the fire in the upwind direction. Cool containers with water spray and move containers from fire to an open area if possible. Extinguishing media: water mist, foam, carbon dioxide, sand.
