Infinite-dilution activity coefficients for systems with α- and β-pinene

Measurements, Correlations, and Modified UNIFAC Predictions of Isobaric Vapor–Liquid Equilibrium Data for the Binary System of Dimethyl Carbonate + Anisole at Different Pressures

“…The pure component bubble temperatures of anisole and DMC at different pressures, measured in this study, are compared with the computed values of the Antoine equation (using constants reported in Table ) in Figure . This figure also shows the experimental data of pure components reported by other researchers at different pressures. − Figure a clearly indicates that boiling point of anisole matches very well at all five pressures with the predicted and other researcher’s data. − Figure b illustrates the % deviation of pure anisole temperature from Antoine’s equation and other researcher’s data, − and the present study indicates a maximum deviation of 0.46%. Further, Figure c shows the boiling point of pure DMC at all five pressures with the predicted and other researchers data, − and the % deviation of pure DMC temperature from Antoine’s equation and other researcher’s data, − as depicted in Figure d, at different pressures show that three of the experimental data points match well with the predictions as estimated within 0.43% deviation, whereas a bit more deviations of 0.78 and 0.93% are observed at 73.33 and 59.99 kPa, respectively.…”

“…Comparison of pure component boiling temperature measurements in the present study with Antoine’s equation prediction and literature data − as a function of pressure: (a) pure Anisole ( p – T ), (b) pure anisole temperature measurements % deviation from Antoine’s equation, (c) pure DMC ( p – T ), and (d) pure DMC temperature measurements % deviation from Antoine’s equation.…”

“…Further, the properties of densities, refractivity, excess molar volumes, and deviations in molar refractivity were also determined at 298.15 K for the binary systems of methanol (1) + DMC or anisole (2). VLE data for some binary mixtures consisting of either DMC or anisole with other components have been reported. − Recently, Song et al have reported isobaric VLE data for the binary mixtures of DMC + dimethyl sulfoxide, DMC + anisole, DMC + diethyl oxalate, and methanol + diethyl oxalate at 101.3 kPa. However, for the binary system of DMC–anisole, isobaric, VLE data have not been reported specifically at 33.33, 46.66, 59.99, 73.33, and 94.66 kPa.…”

Vapor-liquid equilibria for .alpha.-pinene or .beta.-pinene with anisole

“…Isobaric VLB information for -pinene + 3-pinene and for these pinenes with other terpene hydrocarbons like limonene, terpinolene, A3-carene, p-cymene, and 1,8-cineole is available in the literature (3)(4)(5)(6)(7). Only recently, isothermal P-x-y VLB data for -pinene and 3-pinene with heptane, cyclohexane, 1-octene, cyclohexene, 1-butanol, and 1-pentanol, and infinite dilute activity coefficients for these same systems and with aromatics and ethers have been measured and published (8)(9)(10).…”
