The recycle technique with gas chromatography for analysis was used t o measure bubble-point compositions a t conditions correspoinding to those of the dew-point studies reported in RR-19.The resulting K-values are presented here. These data, when combined with the data for methane-ethane-propane, (L), form a complete set for the light paraffin hydrocarbons in the general region from O°F down t o -200 OF and from 25 psia to thecritical . (Not all systems cover the same range of conditions.) A separate investigation by Wichterle (2) on the for defining l i g h t hydrocarbon systems. ethane-propane system between their respective criticals is also useful The r e s u l t s presented here have been or will shortly be published in the permanent literature (-3 , 4-, 5-) . Some tentative values for the n-hexane and 2-heptane K-values were reported to GPA (6). should be used for n-hexane, The values here - Note that for the methane-E-hexane system, an extensive study of the liquid-liquid region is also included, in the Table on page 13 and in Figures 9 and II.
