methacrylic acid usage and synthesis
chemical properties colourless liquid or crystals with an unpleasant odour.
general description a clear colorless liquid (or low-melting solid) with a pungent odor. corrosive to metals and tissue. flash point 170°f. melting point 61°f. may polymerize exothermically if heated or contaminated. if the polymerization takes place inside a container, the container may rupture violently. less dense than water. vapors heavier than air. used to make plastics.
air & water reactions soluble in water.
reactivity profile methacrylic acid reacts with strong oxidizing agents. presents a storage hazard: violent exothermic polymerizations leading to explosion can occur spontaneously, particularly at low inhibitor or stabilizer concentrations [anon., cishc chem. safety summ., 1979, 50, p. 34; bond, j., loss prev. bull., 1991, 101, p. 1].
health hazard inhalation: severe irritation to respiratory tract. eyes: short contact can cause severe damage. skin: causes severe irritation and burns. ingestion: high hazard - may cause death or permanent injury on short exposure to small quantities. other: may affect blood pressure temporarily.
