The Critical Constants of Propane

Abstract

The critical constants of propane (C3H8) are: tc = 96.81±0.01°C, pc = 42.01±0.02 normal atmospheres, vc = 0.195 liter per mole (4.43 cc per gram), dc = 5.13 moles per liter (0.226 gram per cc). The uncertainty in the critical volume and density is 1 percent.
