Physical description & handling notes

• Acrylic acid is a colorless liquid with a distinctive acrid odor. Flash point 130 °F. Boiling point 286 °F. Freezing point 53 °F. Corrosive to metals and tissue. Prolonged exposure to fire or heat can cause polymerization. If polymerization takes place in a closed container, violent rupture may occur. The inhibitor (usually hydroquinone) greatly reduces the tendency to polymerize.
• CBI; Dry Powder; Liquid
• Colorless liquid or solid (below 55 degrees F) with a distinctive, acrid odor; Note: Shipped with an inhibitor (e.g., hydroquinone) since it readily polymerizes; [NIOSH]
• Liquid
• COLOURLESS LIQUID WITH PUNGENT ODOUR.
• Colorless liquid or solid (below 55 °F) with a distinctive, acrid odor.

Documented Uses

• Acrylic acid is used in the manufacture of plastics, in latex applications, in floor polish, in polymer solutions for coatings applications, emulsion polymers, paint formulations, leather finishings, and paper coatings. Acrylic acid is also used as a chemical intermediate.
• Acrylic acid is used to manufacture acrylic resins and acrylates for leather coatings, paints, and adhesives. [ACGIH]
• Used in the manufacture of plastics, molding powder for signs, construction units, decorative emblems and insignias, polymer solutions for coatings applications, emulsion polymers, paints formulations, leather finishings, and paper coatings; ... also used in medicine and dentistry for dental plates, artificial teeth, and orthopedic cement.
• Most acrylic acid is consumed in the form of the polymer. The dominant share of acrylic acid is converted to esters. Today growth is in the demand for superabsorbents (SAPs) for use in diapers and hygienic products. Acrylic acid accounts for 80-85% of raw materials used in the manufacture of SAPs.
• Monomer for polyacrylic and polymethacrylic acids and other acrylic polymer.
• Chemical intermediate for ethyl acrylate, n-butyl acrylate, methyl acrylate, 2-ethylhexyl acrylate; for other specialty acrylates, eg, hydroxyethyl; monomer for polyacrylic acid and salts, eg, thickeners; comonomer with acrylamide for polymers used as flocculants, with ethylene for ion exchange resin polymers, with methyl ester for polymers, eg, thickeners, for other copolymers, eg, with itatonic acid
