TETRAMETHYLAMMONIUM CHLORIDE ICSC: 1099
IMPORTANT DATA
PHYSICAL STATE; APPEARANCE:
HYGROSCOPIC, WHITE CRYSTALS

CHEMICAL DANGERS:
The substance decomposes on heating above 300C 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 20C 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): 368-370C
Density: 1.17 g/cm
Solubility in water, g/100 ml at 20 C: very good
ENVIRONMENTAL DATA

NOTES
Environmental effects from the substance have not been investigated.
