CYCLOHEXANETHIOL ICSC: 0032
IMPORTANT DATA
PHYSICAL STATE; APPEARANCE:
COLOURLESS LIQUID, WITH CHARACTERISTIC ODOUR.

CHEMICAL DANGERS:
The substance decomposes on burning producing toxic gases including sulfur dioxide (see ICSC 0074). Reacts with strong oxidants, reducing agents and metals.

OCCUPATIONAL EXPOSURE LIMITS:
TLV not established.
MAK not established.
ROUTES OF EXPOSURE:
The substance can be absorbed into the body by inhalation, and by ingestion.

INHALATION RISK:
A harmful contamination of the air can be reached rather quickly on evaporation of this substance at 20C.

EFFECTS OF SHORT-TERM EXPOSURE:
The substance is irritating to the eyes, the skin and the respiratory tract. Exposure may result in lowering of consciousness.

PHYSICAL PROPERTIES
Boiling point: 158C
Melting point: -118C
Relative density (water = 1): 0.98
Solubility in water: none
Vapour pressure, kPa at 20C: 1.3
Relative vapour density (air = 1): 4.0
Relative density of the vapour/air-mixture at 20C (air = 1): 1.04
Flash point: 43C c.c.
ENVIRONMENTAL DATA

NOTES
Auto-ignition temperature is unknown in literature. Explosive limits are unknown in literature, although the substance is combustible and has a flash point < 61C.
