CAS #: 34590-94-8
EC Number: 252-104-2

  ACUTE HAZARDS PREVENTION FIRE FIGHTING
FIRE & EXPLOSION Combustible.  Above 74°C explosive vapour/air mixtures may be formed.  NO open flames.  Above 74°C use a closed system and ventilation.  Use water spray, powder, alcohol-resistant foam, carbon dioxide.  In case of fire: keep drums, etc., cool by spraying with water. 

 PREVENT GENERATION OF MISTS!  
  SYMPTOMS PREVENTION FIRST AID
Inhalation Cough. Dizziness. Drowsiness.  Use ventilation, local exhaust or breathing protection.  Fresh air, rest. Refer for medical attention. 
Skin MAY BE ABSORBED! Dry skin. See Inhalation.  Protective gloves. Protective clothing.  Remove contaminated clothes. Rinse and then wash skin with water and soap. 
Eyes Redness. Pain.  Wear safety spectacles.  First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then refer for medical attention. 
Ingestion See Inhalation.  Do not eat, drink, or smoke during work.  Rinse mouth. Refer for medical attention . 

SPILLAGE DISPOSAL CLASSIFICATION & LABELLING
Collect leaking and spilled liquid in sealable plastic containers as far as possible. Wash away remainder with plenty of water.

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 


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. 


OCCUPATIONAL EXPOSURE LIMITS
TLV: 100 ppm as TWA; 150 ppm as STEL; (skin).
MAK: 310 mg/m3, 50 ppm; peak limitation category: I(1); pregnancy risk group: D.
EU-OEL: 308 mg/m3, 50 ppm as TWA; (skin) 

ENVIRONMENT
 

NOTES
Check for peroxides prior to distillation; eliminate if found.
