Material Safety Data Sheet ... acetic anhydride, alcohols + hydrogen cyanide, 2-aminoethanol, ammonium hydroxide, calcium carbide, ... Regulations and the MSDS ... Chronic: Chronic exposure to acetic acid may cause erosion of dental enamel, bronchitis, eye irritation, darkening of the skin, and chronic inflammation of the respiratory tract. Acetic acid can cause occupational asthma. One case of a delayed asthmatic response to glacial acetic acid has been reported in a person with bronchial asthma. The rate constant for the vapor-phase reaction of maleic anhydride with photochemically-produced hydroxyl radicals has been measured as 1.45X10-12 cu cm/molecule-sec at 23 deg C(1). This corresponds to an atmospheric half-life of about 11 days at an atmospheric concentration of 5X10+5 hydroxyl radicals per cu cm(2).
