Henry's Law Gas-Solid Chromatography and Correlations of Virial Coefficients for Hydrocarbons, Chlorofluorocarbons, Ethers, and Sulfur Hexafluoride Adsorbed onto Carbon

Molar Refractivity and Connectivity Index Correlations for Henry's Law Virial Coefficients of Odorous Sulfur Compounds on Carbon and for Gas-Chromatographic Retention Indices

“…Plots of ln B 2s versus 1/T for the 7 gases found in Table 2 gave the slopes, intercepts, and r 2 values given in Table 4. As discussed elsewhere (25), ln B 2s versus 1/T gives slopes that are equal to the E * values expressed in Kelvin. These 7 E * values were in turn correlated with MR values from Table 3 and the result was E * = 245.1MR − 2391.6 r 2 = 0.951, [18] which follows the form of Eq.…”

“…The experimental procedure has been used in previous work (24)(25)(26)(27) and is described in detail elsewhere (28). The specific column used in the present study was the Carbopack C column used in a previous study of the adsorption of selected hydrocarbons and halocarbons (23).…”

“…[4] can be approximated by a simple equation that is most applicable as E * /T takes on larger values. This equation can in turn be expressed (25) as…”

“…Prior work has shown this approach to be an effective means of estimating r g (25). Our objective in the remaining part of this theoretical section is to develop equations that suggest forms of effective correlations of ln B 2s values.…”

“…Using CAChe Project Leader Software, and following the procedures indicated previously, MR and χ values were calculated for each molecule. The [25] and RI = a + b(MR) + c(χ), [26] where a, b, and c are the parameter coefficients. The results of these regression procedures are given in Tables 5, 6, and 7.…”
