Ammonia (data page)

This page provides supplementary chemical data on ammonia.

Vapor–liquid equilibrium data
Table data (above) obtained from CRC Handbook of Chemistry and Physics 44th ed. The (s) notation indicates equilibrium temperature of vapor over solid. Otherwise temperature is equilibrium of vapor over liquid.



Vapor-pressure formula for ammonia:


 * log10P = A – B / (T − C),

where P is pressure in kPa, and T is temperature in kelvins;


 * A = 6.67956, B = 1002.711, C = 25.215 for T = 190 K through 333 K.
