TETRAMETHYLAMMONIUM CHLORIDE

ICSC: 1099

IMPORTANT DATA

PHYSICAL STATE; APPEARANCE:
HYGROSCOPIC, WHITE CRYSTALS

CHEMICAL DANGERS:
The substance decomposes on heating above 300°C producing ammonia, carbon monoxide, hydrogen chloride and nitrogen oxides. Reacts with oxidants.

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:
Evaporation at 20°C is negligible; a harmful concentration of airborne particles can, however, be reached quickly when dispersed.

EFFECTS OF SHORT-TERM EXPOSURE:
The substance is irritating to the eyes, the skin and the respiratory tract. The substance may cause effects on the central nervous system.

PHYSICAL PROPERTIES

Melting point (decomposes): 368-370°C
Density: 1.17 g/cmł
Solubility in water, g/100 ml at 20 °C: very good

ENVIRONMENTAL DATA

NOTES

Environmental effects from the substance have not been investigated.
