Physical Description
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.
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]
COLOURLESS LIQUID WITH PUNGENT ODOUR.
Colorless liquid or solid (below 55 °F) with a distinctive, acrid odor.
