Chemical Safety
0688 ACRYLIC ACID
IMPORTANT DATA
Physical State; Appearance Routes of exposure
COLOURLESS LIQUID, WITH CHARACTERISTIC ODOUR. The substance can be absorbed into the body by inhalation and
through the skin and by ingestion.
Physical dangers
Effects of short-term exposure
The vapour is heavier than air. Vapour forms explosive mixture
with air. Corrosive. The substance is corrosive to the eyes, the skin and
the respiratory tract. Corrosive on ingestion. Inhalation of the
Chemical dangers substance may cause lung oedema (see Notes). The effects may
be delayed.
The substance polymerizes readily due to heating, under the
influence of light, oxygen, oxidizing agents such as peroxides or
other activators (acid, iron salts), with fire or explosion hazard.
Upon heating, toxic fumes are formed. The substance is a
medium strong acid. Reacts violently with strong bases and
amines. Attacks many metals, including nickel and copper.
Occupational exposure limits
TLV: 2 ppm as TWA; (skin); A4 (not classifiable as a human
carcinogen); (ACGIH 2005).
MAK: 10 ppm, 30 mg/m 3; Peak limitation category: I(1); Pregnancy
risk group: C; (DFG 2005).
PHYSICAL PROPERTIES
Boiling point: 141/C Relative vapour density (air = 1): 2.5
Melting point: 14/C Flash point: 54/C c.c.
Relative density (water = 1): 1.05 Auto-ignition temperature: 360/C
Solubility in water: miscible Explosive limits, vol% in air: 2.4-8
Vapour pressure, Pa at 20/C: 413 Octanol/water partition coefficient as log Pow: 0.36 (estimated)
ENVIRONMENTAL DATA
NOTES
Low oxygen content can diminish effectiveness of inhibitor, posing hazardous polymerization situation.
The symptoms of lung oedema often do not become manifest until a few hours have passed and they are aggravated by physical effort.
Rest and medical observation are therefore essential.
Immediate administration of an appropriate inhalation therapy by a doctor or a person authorized by him/her, should be considered.
Do not remelt after solidification, as the substance may be unstable.
An added stabilizer or inhibitor can influence the toxicological properties of this substance, consult an expert.
Card has been partly updated in October 2005. See sections Occupational Exposure Limits, EU classification, Emergency Response.
