Butyl methacrylate Usage And Synthesis
  • Chemical Propertiesclear colourless liquid with an ester-like odour
  • Chemical PropertiesButyl methacrylate is a flammable, colorless liquid with a mild odor.
  • UsesMonomer for resins, solvent coatings, adhe- sives, oil additives; emulsions for textiles, leather, and paper finishing.
  • General DescriptionA clear colorless liquid. Flash point 130°F. Less dense (7.5 lb / gal) than water and insoluble in water. Hence floats on water. Vapors heavier than air. Used to make resins adhesives, and oil additives.
  • Air & Water ReactionsFlammable. Sensitive to moisture. Insoluble in water.
  • Reactivity ProfileButyl methacrylate reacts exothermically with acids. Reacts with oxidizing agents. Strong oxidizing acids may cause a reaction that is sufficiently exothermic to ignite the reaction products. Heat is generated with caustic solutions. Generates flammable hydrogen with alkali metals and hydrides. Polymerizes easily .
  • HazardToxic by ingestion. Moderate fire risk.
  • Health HazardInhalation may cause nausea because of offensive odor. Contact with liquid causes irritation of eyes and mild irritation of skin. Ingestion causes irritation of mouth and stomach.
  • Fire HazardBehavior in Fire: Containers may explode due to polymerization.
  • Fire HazardFlash Point (°F): 150 ℃; Flammable Limits in Air (%): 2-8; Fire Extinguishing Agents: Dry chemical, foam, carbon dioxide; Fire Extinguishing Agents Not To Be Used: Water may be ineffective; Special Hazards of Combustion Products: Not pertinent; Behavior in Fire: Containers may explode; Ignition Temperature (°F): 562; Electrical Hazard: No data; Burning Rate: 4.8 mm/min.
  • Chemical ReactivityReactivity with Water No reaction; Reactivity with Common Materials: No reactions; Stability During Transport: Stable; Neutralizing Agents for Acids and Caustics: Not pertinent; Polymerization: May occur upon exposure to heat; Inhibitor of Polymerization: 9-15 ppm monomethyl ether of hydroquinone; 90-120 ppm hydroquinone.
  • Safety ProfileModerately toxic by intraperitoneal route. Mddly toxic by ingestion, inhalation, and skin contact. An experimental teratogen. Experimental reproductive effects. A skin irritant. Flammable liquid when exposed to heat or flame. Explosive in the form of vapor when exposed to heat or flame. Violent polymerization can be caused by heat, moisture, oxidizers. To fight fire, use foam, dry chemical, CO2. When heated to decomposition it emits acrid smoke and irritating fumes.
  • Potential ExposureForms an explosive mixture with air. Unless inhibitor is maintained at the proper level, oxidizers, heat, ultraviolet light, contamination, or moisture may cause polymerization. May accumulate static electrical charges and cause ignition of its vapors.
  • ShippingUN2227 Butyl methacrylate, stabilized, Hazard Class: 3; Labels: 3—Flammable liquid.
  • Purification MethodsPurify as for butyl acrylate. [Beilstein 2 IV 1525.]
  • IncompatibilitiesForms an explosive mixture with air. Unless inhibitor is maintained at the proper level, oxidizers, heat, ultraviolet light, contamination, or moisture may cause polymerization. May accumulate static electrical charges and cause ignition of its vapors
  • Waste DisposalDissolve or mix the material with a combustible solvent and burn in a chemical incinerator equipped with an afterburner and scrubber. All federal, state, and local environmental regulations must be observed.
