Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Additional information

The boiling point of anhydrous ammonia is reported to be -33 °C (Handbook of Compressed Gases) and -33.33 °C (CRC Handbook, 2006).

The boiling point of aqueous ammonia (30% solution) is reported to be 36 degrees Celsius (Young, 2003). The boiling point of a range of concentrations of aqueous ammonia was measured to be 59 to 195F for a concentration of 35.28 to 1.62 %wt ammonia in solution (Perry's Chemical Engineer's Handbook).
