Flash Point:-78.5±6.3 °C
Refractive Index:1.196
Water Solubility:Soluble in ethanol
Storage Conditions:Grounding and bonding required. Store in a tightly closed container. Store below 49 C. Store in a cool, dry place. Store in a well-ventilated area. Keep separated from incompatible substances.
Vapor Pressure:1.26X10+4 mm Hg at 25 deg C
Toxicity:LC50 inhalation in mouse: 1810gm/m3
OH:1.09e-14 cm3/molecule*sec
Henrys Law Constant:Henry's Law constant = 0.292 atm-cu m/mol at 25 °C (est)
Experimental Properties:Global Warming Potential (GWP): Chemical: HFC-32; GWP: 675 (100-Year Time Horizon)|Critical volume: 121 cu cm/mole|Dipole moment: 1.98 D|Hydroxyl radical reaction rate constant = 1.10X10-14 cu cm/molec-sec at 25 °C
Air and Water Reactions:Highly flammable. Insoluble in water. Easily ignited by heat, sparks or flames. Forms explosive mixtures with air
Reactive Group:Fluorinated Organic Compounds
Reactivity Alerts:Highly Flammable
Reactivity Profile:DIFLUOROMETHANE can react with some metals to form dangerous products. May react violently with aluminum. Incompatible with strong oxidizing and reducing agents. Also incompatible with many amines, nitrides, azo/diazo compounds, alkali metals, and epoxides.
Critical Temperature & Pressure:Critical temperature: 351.28 K; critical pressure: 5.79 MPa
