Ammonia (data page)

This page provides supplementary chemical data on ammonia.

Structure and properties

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: [Lange's Handbook of Chemistry, 10th ed. page 1436]

:::log₁₀(P) = 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
