This page provides supplementary chemical data on ammonia.
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:
where P is pressure in kPa, and T is temperature in kelvins;
The handling of this chemical may incur notable safety precautions... It is highly recommend that you seek the Safety Data Sheet (SDS) for this chemical from a reliable source and follow its directions.
Except where noted otherwise, data relate to standard ambient temperature and pressure.
