Chemical Formula: CH2Br2 UN Number: 2664 Category of Hazardness: Flammable toxic liquid. Appearance: Colorless transparent liquid Dibromomethane Content: 99.0 PCT MIN Bromochloromethane: 0.8PCT MAX Dichloromethane: 0.1PCT MAX Acidity (HBr): 0.05PCT MAX Boiling Point: 97.0 oC Specific Gravity: 2.4969 (20 oC ) Vapor Pressure: 44.4mmHg (25 oC ) Vapor Specific Gravity: 6.05 ( air = 1) Solubility in Water: 11.7 g/1000 g water (15 oC) Corrosivity: No Harmful Polymerization: No Light Sensitivity: No
Reactivity & Insolubility: When the carbon halogenide mixes with potassium or other alloys, it is sensitive to the shock and it may explode because of the strenuous movement or light irradiation. Decomposability: Produces bromine hydride-containing toxic gas when carries on the thermal decomposition.
Main Use: As the pesticide intermediate, the dibromomethane is the main raw material for synthesizing new type highly effective and broad-spectrum bactericide, it also is the raw material of large tonnage acaricide. Dibromomethane is a kind of good fire retardant, when add it into the polymer, it can effectively reduces the combustion heat when the plastic's burning.
