methyl methacrylate usage and synthesis |
chemical properties | clear liquid |
general description | a clear colorless liquid. slightly soluble in water and floats on water. vapors heavier than air. vapors irritate the eyes and respiratory system. containers must be heavily insulated or shipped under refrigeration. an inhibitor such as hydroquinone, hydroquinone methyl ester and dimethyl t-butylphenol is added to keep the chemical from initiating polymerization. the chemical may polymerize exothermically if heated or contaminated with strong acid or base. if the polymerization takes place inside a container, the container may rupture violently. used to make plastics. |
air & water reactions | highly flammable. very slightly soluble in water. |
reactivity profile | methyl methacrylate, may polymerize if contaminated or subjected to heat. if polymerization takes place in a container, the container is subject to violent rupture. oxidizes readily in air to form unstable peroxides that may explode spontaneously [bretherick 1979. p.151-154, 164]. peroxides may also initiate exothermic polymierization of the bulk material [bretherick 1979. p. 160]. benzoyl peroxide was weighed into a beaker that had previously been rinsed with methyl methacrylate. the peroxide catalyzed polymerization of the methyl methacrylate and the build-up of heat ignited the remaining peroxide [mca case history 996. 1964]. |
health hazard | irritation of eyes, nose, and throat. nausea and vomiting. liquid may cause skin irritation. |
fire hazard | behavior in fire: vapor is heavier than air and may travel a considerable distance to a source of ignition and flash back. containers may explode in fire or when heated because of polymerization. |
