Solubility of Ethane in N-Formyl Morpholine

Abstract

Measurements of the solubility of ethane in N-formyl morpholine have been made over a range of temperatures from (298 to 403) K. Pressures varied between (0.1 and 20.3) MPa. The data were correlated with the Peng−Robinson equation of state.

Solubility data for toluene in various aqueous alkanolamine solutions

“…The literature data appear a little dispersed, but close to the new data except those measured by Stephenson [9] which are significantly different (see figure 2). In fact, a minimum in toluene Nomenclature A, B, C, D, E adjustable parameters, equations (4) and (6 Greek letters c activity coefficient U fugacity coefficient solubility vs. temperature occurs around 300 K. This minimum is confirmed by Jou and Mather [12]. Moreover, the extrapolation of the tendency curve determined on our experimental data indicates the existence of a minimum too.…”

“…In fact, up to 0.5 MPa, methane has a very small influence on toluene solubility (deviation is less than 1% between benzene mole fraction measured at 0.5 MPa and benzene mole fraction calculated by extrapolation to zero methane partial pressure as described in ref [2] and [5]). Several authors have studied the solubility of toluene in pure water [6,[8][9][10][11][12]. Corresponding data are presented in table 3.…”

Partition of compounds from water and from air into amides

“…We have extrapolated these to 298K through plots of log γ ∞ against 1/T(K) or plots of log Vg o against 1/T(K) for each solute and obtained values of log K s and log P s for 50 solutes. In addition, there are data for a few more gases, 90, 91 making 55 solutes in all as given in Table S4. Application of eqn (3) yielded eqn (11).…”

Spectroscopic study of mutual solubilities of water and benzene at high temperatures and pressures

“…Recently, solubilities of aqueous systems at high temperatures have been paid much attention. These data are required for pollution assessment of high-temperature water discharged from laboratories and industrial plants, [9][10][11][12][13] and moreover, for designing an environment protecting technology that uses high-temperature water in the sub-to supercritical condition as a reaction medium for destruction of toxic waste chemicals. 14 -17 In addition, the high-temperature solubility data are indispensable to designs, operations and maintenance of plants for oil refineries and petrochemical industry.…”

“…The transferring of a sample without disturbing equilibrium and/or without composition change is rather difficult, particularly at high temperatures and pressures. 10,21 Therefore most of the solubility data of the water-benzene system have been limited at the three-phase equilibrium pressures, 9,10,13,21 and a few other pressures at higher temperatures. [22][23][24][25] In addition, effect of pressure on the mutual solubilities has not been fully understood, in contrast to the temperature effect, namely the significant increase in the mutual solubilities with increasing temperature.…”
