1,2,3-TRICHLOROBENZENE ICSC: 1222
IMPORTANT DATA
PHYSICAL STATE; APPEARANCE:
WHITE CRYSTALS, WITH CHARACTERISTIC ODOUR.

CHEMICAL DANGERS:
The substance decomposes on burning producing toxic and corrosive fumes including hydrogen chloride. Reacts with strong oxidants.

OCCUPATIONAL EXPOSURE LIMITS:
TLV not established.
MAK: 5 ppm, 38 mg/m; H; Peak limitation category: II(2); Pregnancy risk group: D; (DFG 2003).
ROUTES OF EXPOSURE:
The substance can be absorbed into the body by inhalation of its aerosol and by ingestion.

INHALATION RISK:
A harmful contamination of the air will be reached rather slowly on evaporation of this substance at 20C; on spraying or dispersing, however, much faster.

EFFECTS OF SHORT-TERM EXPOSURE:
The substance is irritating to the eyes and the respiratory tract.

PHYSICAL PROPERTIES
Boiling point: 218.5C
Melting point: 53.5C
Density: 1.45 g/cm
Solubility in water: very poor
Vapour pressure, Pa at 25C: 17.3
Relative vapour density (air = 1): 6.26
Flash point: 112.7C c.c.
Octanol/water partition coefficient as log Pow: 4.05
ENVIRONMENTAL DATA
The substance is very toxic to aquatic organisms. Bioaccumulation of this chemical may occur in fish.
NOTES
UN number 2321 refers to liquid trichlorobenzenes. Liquid trichlorobenzenes are marine pollutants. See ICSC 1049 1,2,4-Trichlorobenzene and 0344 1,3,5-Trichlorobenzene.
