PHYSICAL & CHEMICAL INFORMATION
Physical State; Appearance COLOURLESS LIQUID WITH CHARACTERISTIC ODOUR. Physical dangers Chemical dangers The substance can presumably form explosive peroxides in contact with air. Reacts violently with strong oxidants. Attacks many metals. This produces flammable/explosive gas (hydrogen - see ICSC 0001).	Formula: C₇H₁₆O₃ / H₃COC₃H₆OC₃H₆OH Molecular mass: 148.2 Boiling point: 190°C Melting point: -80°C Relative density (water = 1): 0.95 Solubility in water: very good Vapour pressure, Pa at 26°C: 53.3 Relative vapour density (air = 1): 5.1 Relative density of the vapour/air-mixture at 20°C (air = 1): 1.0 Flash point: 74°C Auto-ignition temperature: 270°C Explosive limits, vol% in air: 1.3-10.4

Physical dangers

Chemical dangers
The substance can presumably form explosive peroxides in contact with air. Reacts violently with strong oxidants. Attacks many metals. This produces flammable/explosive gas (hydrogen - see ICSC 0001).

Formula: C₇H₁₆O₃ / H₃COC₃H₆OC₃H₆OH
Molecular mass: 148.2
Boiling point: 190°C
Melting point: -80°C
Relative density (water = 1): 0.95
Solubility in water: very good
Vapour pressure, Pa at 26°C: 53.3
Relative vapour density (air = 1): 5.1
Relative density of the vapour/air-mixture at 20°C (air = 1): 1.0
Flash point: 74°C
Auto-ignition temperature: 270°C
Explosive limits, vol% in air: 1.3-10.4

EXPOSURE & HEALTH EFFECTS
Routes of exposure The substance can be absorbed into the body by inhalation of its vapour, through the skin and by ingestion. Effects of short-term exposure The vapour is irritating to the eyes and respiratory tract. The substance may cause effects on the central nervous system. This may result in narcosis.	Inhalation risk A harmful contamination of the air will be reached rather slowly on evaporation of this substance at 20°C. Effects of long-term or repeated exposure The substance defats the skin, which may cause dryness or cracking.
