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.;Acrylic acid, [waste] appears as a colorless liquid with a distinctive acrid odor. Combustible. Flash point 130°F. Boiling point 286°F. Freezing point 121°F. Corrosive to metals and tissue. May polymerize under prolonged exposure to fire or heat. If polymerization occurs in a container violent rupture may occur. Generally shipped with an inhibitor such as hydroquinone to prevent polymerization.;Liquid;Liquid;COLOURLESS LIQUID WITH PUNGENT ODOUR.;Colorless liquid or solid (below 55°F) with a distinctive, acrid odor.;Colorless liquid or solid (below 55°F) with a distinctive, acrid odor. [Note: Shipped with an inhibitor (e.g., hydroquinone) since it readily polymerizes.]
