Volumetric, acoustic, and viscometric studies of molecular interactions in binary mixtures of dipropylene glycol dimethyl ether with 1-alkanols at 298.15K

Thermodynamic and transport properties of (1,2-ethanediol+1-nonanol) at temperatures from (298.15 to 313.15)K

“…It is also interesting to note, that in these mixtures positive c D curves are always accompanied by negative K E S ones. Similar relationship between c D and K E S is reported also for aqueous mixtures of 2-diethylaminoethanol [41] and mixtures of dipropylene glycol dimethyl ether with 1-alkanols [42]. This is in agreement with the recently suggested strict correlation between extrema of c D and K E S of binary alkanol systems [43].…”

Volumetric and Acoustic Properties for Binary Mixtures of Dipropylene Glycol Monopropyl Ether with Alkylamines at Temperatures Between 288.15 K and 308.15 K

“…In order to perform a numerical comparison of the prediction capability of the model, the experimental density and ultrasonic speed data at different temperatures were fitted with the model and the average percentage deviation (APD) was calculated as AP D = 100 N y exptl − y calcd y exptl (11) where N represents the number of experimental data in each data set. The optimum number of constants A j , in each case, was determined from an examination of the APD values.…”

“…As a part of our ongoing program of research on thermodynamic and acoustic properties of binary liquid mixtures containing alkoxyethanols or alkoxypropanols, we have recently reported measurements of excess molar volumes, viscosities, and speeds of sound of binary mixtures of alkoxyalkanols with n-alkylamines [7][8][9][10], 1-alkanols [11][12][13][14][15][16], or amides [17]. As a part of this continuing work, the experimental results for the densities, ρ, and speeds of sound, u, are reported in this article for the binary systems of dipropylene glycol monopropyl ether (DPGMPE) with n-butylamine, dibutylamine, and tributylamine over the complete composition range and those of the pure liquid components at atmospheric pressure and temperatures of (288.…”

Densities and Viscosities of Ternary System n-Dodecane (1) + Bicyclohexyl (2) + n-Butanol (3) and Corresponding Binaries at T = (293.15 to 333.15) K

“…It is an ideal model compound to research the properties of fuels. Bicyclohexyl has high density and good thermal stability, which is usually found in coal-derived fuels. − In consideration of similar molecular structure to decalin and with same carbon number as n -dodecane, bicyclohexyl has potential to become a surrogate component of jet fuels. − N -Butanol is widely used as fuel additive to enhance the octane rating of fuel, improve fuel burning characteristics, and reduce atmospheric pollution . In addition, n -butanol is a kind of bioenergy alternative to petroleum and has a chance to promote the combustion process of hydrocarbon fuel as additive. , Hence, detailed data of physical properties for the ternary system n -dodecane + bicyclohexyl + n -butanol can provide guidance for the research of jet fuels.…”
