Literature References: Occurs in the urine of alligators: Coulson, Hernandez, Proc. Soc. Exp. Biol. Med. 88, 682 (1955). Usually prepd by passing an excess of carbon dioxide through concd ammonia water. Manuf: GB 304872 (1927 to I.G. Farben.); Brooks, GB 742386 (1955 to I.C.I.). See also Ammonium Carbonate.
Properties: Shiny, hard, colorless or white prisms or crystalline mass. Faint odor of ammonia. Comparatively stable at room temp. Volatile with decompn at about 60°. The white fumes given off consist of NH3 21.5%, CO2 55.7%, H2O vapor 22.8%. Rate of decompn increases as temp rises. mp 107.5° (very rapid heating). Soly in water: 14% (10°); 17.4% (20°); 21.3% (30°). Decomposed by hot water. One gram dissolves in 10 ml glycerol (pharmaceutical grade). pH of 0.1N soln in water at 25° = 7.8. Insol in alcohol and acetone. Negative heat of solution.
Melting point: mp 107.5° (very rapid heating)
NOTE: Pharmaceutical Incompat: Acids, caustic alkalies.
Use: In baking powder formulations; in cooling baths (one kg dissolved in 5 liters H2O at 17° lowers it to 7°); in fire extinguishers; manuf porous plastics, ceramics; manuf dyes, pigments; in compost heaps to accelerate decompn; as fertilizer; for defatting textiles; in cold wave solns; in chrome leather tanning; to remove gypsum from heat exchanges and other processing equipment.
Therap-Cat: Expectorant.
Therap-Cat-Vet: Expectorant. Used in bloat, colic.
