✦ Synopsis

Measurements of ( p, ρ, T ) for NH 3 at specified temperatures and pressures in the compressed liquid phase were carried out with a metal-bellows variable volumometer along 10 isotherms between T = 310 K and T = 400 K at pressures from the vapour pressure to p = 17 MPa. The results cover the high-density region from ρ = 343 kg • m -3 to ρ = 601 kg • m -3 . The experimental uncertainities in temperature T , pressure p, and density ρ were estimated to be less than ±4 mK, ±1.0 • 10 -3

• p, and ±1.0 • 10 -3

• ρ, respectively. Measurements of the vapour pressure and saturated liquid density at temperatures from T = 310 K to T = 400 K are also reported. On the basis of the present results, the isothermal compressibility and the cubic expansion coefficient are illustrated as a function of temperature and pressure.
