THIODIGLYCOL ICSC: 1601
IMPORTANT DATA
PHYSICAL STATE; APPEARANCE:
VISCOUS COLOURLESS LIQUID, WITH CHARACTERISTIC ODOUR.

CHEMICAL DANGERS:
The substance decomposes on heating producing toxic and corrosive fumes including acetic acid fumes, hydrogen sulfide and sulfur oxides. Reacts violently with strong acids and strong oxidants to produce hydrogen sulfide.

OCCUPATIONAL EXPOSURE LIMITS:
TLV not established. MAK not established.
INHALATION RISK:
Evaporation at 20C is negligible; a harmful concentration of airborne particles can, however, be reached quickly on spraying.

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

PHYSICAL PROPERTIES
Melting point: -18 - -10C
Relative density (water = 1): 1.18
Solubility in water, g/100 ml at 20C: 100
Vapour pressure, Pa at 25C: 0.43
Relative vapour density (air = 1): 4.22
Flash point: 160C o.c.
Auto-ignition temperature: 260C
Explosive limits, vol% in air: 1.2-5.2
Octanol/water partition coefficient as log Pow: -0.75
ENVIRONMENTAL DATA

NOTES
The boiling point is higher than the autoignition temperature.
