Aliphatic HC's, iso-paraffins
March 2001
CAS #: 64741-65-7
UN #: 1268

  ACUTE HAZARDS PREVENTION FIRE FIGHTING
FIRE & EXPLOSION Flammable.  Above 44°C explosive vapour/air mixtures may be formed.  NO open flames, NO sparks and NO smoking.  Above 44°C use a closed system, ventilation and explosion-proof electrical equipment.  Use water spray, alcohol-resistant foam, powder, carbon dioxide.  In case of fire: keep drums, etc., cool by spraying with water. 

 PREVENT GENERATION OF MISTS!  
  SYMPTOMS PREVENTION FIRST AID
Inhalation Dizziness. Headache. Drowsiness. Nausea. Unconsciousness.  Use ventilation, local exhaust or breathing protection.  Fresh air, rest. Refer for medical attention. 
Skin Dry skin.  Protective gloves.  Remove contaminated clothes. Rinse skin with plenty of water or shower. 
Eyes Redness.  Wear safety goggles.  First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then refer for medical attention. 
Ingestion Cough. Diarrhoea. Sore throat. Vomiting. Further see Inhalation.  Do not eat, drink, or smoke during work.  Do NOT induce vomiting. Refer for medical attention . See Notes. 

SPILLAGE DISPOSAL CLASSIFICATION & LABELLING
Ventilation. Collect leaking and spilled liquid in sealable containers as far as possible. Absorb remaining liquid in sand or inert absorbent. Then store and dispose of according to local regulations. Do NOT wash away into sewer. Personal protection: filter respirator for organic vapours of low boiling point adapted to the airborne concentration of the substance. 

According to UN GHS Criteria

 

Transportation
UN Classification
UN Hazard Class: 3; UN Pack Group: III 

STORAGE
Fireproof. Separated from strong oxidants. Well closed. 
PACKAGING
 
NAPHTHA (PETROLEUM), HEAVY ALKYLATE ICSC: 1382
PHYSICAL & CHEMICAL INFORMATION

Physical State; Appearance
COLOURLESS LIQUID. 

Physical dangers
The vapour is heavier than air and may travel along the ground; distant ignition possible. 

Chemical dangers
Reacts with strong oxidants. This generates fire and explosion hazard. 


Boiling point: 172-215°C
Melting point: <-30°C
Density: 0.75-0.79 g/cm³
Solubility in water: none
Vapour pressure, kPa at 20°C: 0.1-0.2
Flash point: >=44°C c.c.
Auto-ignition temperature: 355°C
Explosive limits, vol% in air: 0.6-8.0 


EXPOSURE & HEALTH EFFECTS

Routes of exposure
The substance can be absorbed into the body by inhalation of its vapour and by ingestion. 

Effects of short-term exposure
The vapour is mildly irritating to the eyes. The substance may cause effects on the central nervous system. Exposure to high concentrations of vapour could cause unconsciousness. If this liquid is swallowed, aspiration into the lungs may result in chemical pneumonitis. 

Inhalation risk
No indication can be given about the rate at which a harmful concentration of this substance in the air is reached on evaporation at 20°C. 

Effects of long-term or repeated exposure
The substance defats the skin, which may cause dryness or cracking. See Notes. 


OCCUPATIONAL EXPOSURE LIMITS
 

ENVIRONMENT
The substance is toxic to aquatic organisms. 

NOTES
This is a mixture of C9-C14 iso- and n-paraffins.
Neither the concentration of aromatics nor of hexane is greater than 0.1 % by volume.
Note P: the EU classification as carcinogen (R45) does not apply if it can be shown that the benzene content is below 0.1% by volume.
Depending on the raw material and the production processes, the composition and physical properties of this solvent can vary considerably.
The symptoms of chemical pneumonitis do not become manifest until a few hours or even a few days have passed.
