Administrative data
First-aid measures
Emergency measure - Inhalation: Remove patient to fresh air, seek medical attention.
Emergency measure - Eyes: Rinse immediately with plenty of water for at least 15
minutes. Seek medical attention.
Emergency measure - Skin: Wash immediately with soap and water. Discard contaminated
leather items.
Emergency measure - Ingestion: Seek medical attention immediately.
Fire-fighting measures
Recommended extinguishing agent: Recommended extinguishing agents: Water, carbon dioxide,
foam or dry powder may be used.
Product arising from burning: Products arising from pyrolysis: Products of combustion may
contain oxides of carbon and soot and, under certain
conditions, oxides of tungsten and/or hydrogen chloride,
aldehydes and carboxylic acids may be formed.
Protective equipment: Protective equipment: Full protective clothing, gloves,
goggles and a self-contained breathing apparatus should be
worn.
Accidental release measures
Emergency measures in case of spillage: Wear face mask with fresh air supply and protective
clothing. Ventilate the spill site and remove all sources
of ignition. Add soda ash to the spill to neutralise
hydrogen chloride. Small spills: allow toluene to
evaporate. Sweep up spill into suitable plastic
(polypropylene) containers. Large spills: place in suitable
containers and dispose of at a suitable facility. The
substance contains toluene, dispose of in accordance with
national and local regulations. Do not allow spillages to
enter the aquatic environment.
Handling and storage
Handling: Observe the usual precautions for handling highly flammable
chemicals. Ensure adequate ventilation. Avoid inhalation
and contact with skin and eyes. Protective clothing, gloves
and goggles should be worn. Ensure eyewash fountains and
safety showers are easily accessible.
Storage: Store under dry nitrogen in a well-ventilated area. Keep
away from sources of ignition and strong oxidising agents.
Do not allow build-up of static electric charges.

Stability and reactivity
Danger other than fire: Other dangers: The substance reacts with moist air evolving
hydrogen chloride.
Chemical reaction with water: Chemical reaction with water: The substance reacts with
water to produce nonylphenol, 2,4-pentanedione
(acetylacetone), hydrogen chloride and tungsten oxide.
Disposal considerations
Industry - Possibility of recovery/recycling: The substance is very sensitive to oxidation resulting in
deactivation; hence recovery for recycling is not possible.
Industry - Possibility of neutralisation: The concentrated catalyst solution will be deactivated in
the presence of water and oxygen. Neutralize using soda ash
and allow the toluene to evaporate. The deactivated product
should be handled as chloride and tungsten containing
waste.
Industry - Possibility of destruction: controlled discharge: Not recommended.
Industry - Possibility of destruction - incineration: The substance can be disposed of by incineration at a
suitable facility. Waste gas treatment to remove hydrogen
chloride should be fitted. The residue will contain
tungsten oxide(s).
Industry - Possibility of destruction - water purification: Not recommended. The substance should not be discharged to
the aquatic environment as its hydrolysis products are
toxic to aquatic species.
Public at large - Possibility of recovery/recycling: The substance will not enter the public domain.
