Henry’s constants of butane, isobutane, 1-butene and isobutene in methanol at 255–320 K

Henry’s constants of carbon dioxide in methanol at 250–500 K

“…The fugacity coefficients of carbon dioxide in the vapor phase, ϕ V g , and the compressibility factors of the vapor mixtures, Z, are approximately equal to 1 as shown in Table 1. It was shown in a previous paper [5] that these approximations are justified at low pressures. Table 1 Henry's constants of carbon dioxide in methanol The volume of the saturated gas flowing out of the equilibrium cell, V, can be evaluated from…”

“…The experimental apparatus described previously [5] was used to measure the Henry's constants at lower temperatures than 320 K. About 43 cm 3 of the degassed methanol was introduced into the equilibrium cell, which had a volume of about 44 cm 3 , and the accurate quantity was determined by mass. Then the equilibrium cell was immersed in a constant-temperature bath (filled with ethylene glycol + water) and connected to a supply of solute gas and helium.…”

“…The composition of the gas leaving the cell is periodically sampled and analyzed by gas chromatography. The peak area, S, of the solute decreases exponentially with the volume of inert gas flowing out of the cell by the following rigorous relation [5,6] ln…”

Henry’s constants and infinite dilution activity coefficients of propane, propene, butane, isobutane, 1-butene, isobutene, trans-2-butene, and 1,3-butadiene in isobutanol and tert-butanol

“…The composition of the gas leaving the cell is periodically sampled and analyzed by gas chromatography. The peak area, S, of the solute decreases exponentially with the volume of inert gas flowing out from the cell, and this relationship was derived rigorously in the previous paper [2] as follows…”

“…In previous work [2][3][4][5], the HenryÕs constants of propane, propene, butane, isobutane, 1-butene, isobutene, trans-2-butene, and 1,3-butadiene in methanol, 1-propanol, 2-propanol, 1-butanol, and 2-butanol were measured with this method. For these highly volatile solutes and solvents, rigorous expression was derived for data reduction.…”
