0210 ACETYL CHLORIDE
IMPORTANT DATA
Physical State; Appearance Routes of exposure
COLOURLESS FUMING LIQUID, WITH PUNGENT ODOUR. The substance can be absorbed into the body by inhalation of
its vapour and by ingestion.
Physical dangers
Inhalation risk
The vapour is heavier than air and may travel along the ground;
distant ignition possible. A harmful contamination of the air can be reached very quickly
on evaporation of this substance at 20/C.
Chemical dangers
Effects of short-term exposure
The substance decomposes on heating and on burning
producing toxic and corrosive fumes including hydrogen chloride The vapour is irritating to the eyes and the respiratory tract. The
(see ICSC 0163), phosgene (see ICSC 0007). Reacts violently substance is corrosive to the eyes and the skin. Corrosive on
with water, alcohols, acids, bases, certain powdered metals and ingestion. Inhalation of the vapour may cause lung oedema (see
many other compounds causing fire and explosion hazard. Notes). Exposure may result in unconsciousness. The effects
Attacks many metals in presence of water. Products of may be delayed. Medical observation is indicated.
hydrolysis in water include corrosive hydrochloric acid and acetic
acid. Effects of long-term or repeated exposure
Repeated or prolonged contact with skin may cause dermatitis.

MAK not established.
PHYSICAL PROPERTIES
Boiling point: 51/C Relative vapour density (air = 1): 2.7
Melting point: -112/C Flash point: 5/C c.c.
Relative density (water = 1): 1.11 Auto-ignition temperature: 390/C
Solubility in water: reaction Explosive limits, vol% in air: 7.3-19
Vapour pressure, kPa at 20/C: 32
ENVIRONMENTAL DATA
This substance may be hazardous to the environment; special attention should be given to water.
NOTES
Reacts violently with fire extinguishing agents such as hydrous agents (water, foam).
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 use in the vicinity of a fire or a hot surface, or during welding.
Card has been partly updated in October 2004. See sections Occupational Exposure Limits, EU classification, Emergency
Response.
