Appearance:Methacrylonitrile, stabilized appears as a clear colorless liquid. Less dense than water. Flash point 55°F. Boiling point 195°F. Very be toxic by ingestion, inhalation and skin absorption. Used to make plastics and coatings.
Density:0.8001 g/cm3 @ Temp: 20 °C
Melting Point:-35.8 °C
Boiling Point:90.3 °C @ Press: 760 Torr
Flash Point:54 °F
Refractive Index:n 20/D 1.400(lit.)
Water Solubility:H2O: 2.57 g/100 mL (20 ºC)
Storage Conditions:2-8°C
Vapor Pressure:64 mm Hg ( 20 °C)
Vapor Density:2.31
Toxicity:Oral-Rat LD50: 120 mg/kg; Oral-Mouse LD50: 17 mg/kg
Flammability characteristics:Inflammable in case of open flame, high temperature, oxidant; burning produces toxic nitrogen oxides and cyanide fumes
Explosive limit:vol% in air: 2.8
Odor:Odor-like bitter almonds.
Experimental Properties:VAP: 40 mm Hg @ 13 °C; 65 mm Hg @ 25 °C; 100 mm Hg @ 33 °C|Saturated concn: 208 g/cu m @ 20 °C, 318 g/cu m @ 30 °C|Heat of polymerization = 64.0 kJ/mol; aqueous azeotrope = 84% water
Air and Water Reactions:Highly flammable. Soluble in water.
Reactive Group:Nitriles
Reactivity Alerts:Highly Flammable
Reactivity Profile:METHACRYLONITRILE is a colorless, flammable, toxic liquid. Explosive in the form of vapor when exposed to heat, flame or sparks. When heated to decomposition it emits toxic fumes of nitrile and oxides of nitrogen [Lewis, 3rd ed., 1993, p. 829].
Flammable Limits:Lower flammable limit: 2%; upper flammable limit: 6.8%|Class IB Flammable Liquid: Fl.P. below 73°F and BP at or above 100°F.
Physical Dangers:The vapour is heavier than air and may travel along the ground; distant ignition possible. Vapours are uninhibited and may polymerize, causing blockage of vents.
Heat of Vaporization:31.8 kJ/mol @ BP
