Vapor-pressure relations for 15 hydrocarbons

Experimental values of vapor pressure for 15 hydrocarbons are measured in the low-pressure range 0.1 to 25 mm Hg by means of the inclined-piston deadweight gage and in the range 71 to 2,025 mm Hg by means of comparative ebulliometers. Correlations of the present results with selected literature values are given in terms of Cox equations.
