Ethyl methacrylate Usage And Synthesis
Chemical Properties colourless liquid with an unpleasant odour
General Description A colorless moderately toxic liquid with an acrid odor. Flash point of 70°F. Boiling point 278°F. Vapors irritate the eyes and respiratory system. Less dense than water. Not soluble in water. Used to make polymers and other chemicals.
Air & Water Reactions Highly flammable. A very dangerous fire and explosion hazard. Not soluble in water.
Reactivity Profile May polymerize if heated for prolonged periods or accidentally contaminated. If polymerization takes place inside a container, the container may violently rupture. Can react with oxidizing materials. When heated to decomposition Ethyl methacrylate emits irritating fumes and acrid smoke [Sax, 9th ed., 1996, p. 1576].
Health Hazard Inhalation may cause irritation of the mucous membrane. Ingestion causes irritation of mouth and stomach. Contact with liquid irritates eyes and skin.
Fire Hazard Behavior in Fire: Sealed containers may rupture explosively if hot. Heat can cause a violent polymerization reaction with rapid release of energy. Vapors are heavier than air and can travel to a source of ignition and flash back.
