Temperature Dependence of the Interaction Second Virial Coefficient Using Gas-Liquid Chromatography
Measurement of the interaction second virial coefficient (B₁₂) of nitrogen with methanol, ethanol, n-propanol, and n-butanol on the di-isodecyl phthalate stationary phase has been made with a high pressure gas-liquid chromatograph (g.l.c.). the investigation was made up to 2.5 atm and from 30 to 70°C. B₁₂ data from the static method exist for the nitrogen + methanol system. They generally agree well with the B₁₂ from the g.l.c. method, but show a slightly different trend. the errors associated with the B₁₂ values from g.l.c. are about ± 17 cm³ mol⁻¹.
