Pressure‐volume‐temperature behaviour of ethyl alcohol in the gaseous and liquid states

PVT data available in the literature for ethyl alcohol have been utilized for the development of a reduced density correlation for this substance. The critical constants accepted in this study are those determined by Young ₁ T_c = 516.3°K, P_c = 62.96 atm, and _pe = 0.276 g/cm.₃. To extend the available PVT information for ethyl alcohol over the complete range of temperatures up to T_R = 1.8 and pressures up to P_R = 40, use has been made of the available reduced density correlation of ammonia₂ and the Nelson‐Obert compressibility factor charts₃.
