We measure the density and surface tension of four binary mixtures of 2,2,4-trimethylpentane + n-heptane and n-octane, and butanenitrile and ethyl acetate + benzene, from (293.15 to 323.15) K at atmospheric pressure. Densities are measured using a vibrating tube densimeter while surface tension is measured with a drop volume tensiometer. Excess molar volumes and surface tension deviations are calculated from the experimental measurements. Results are correlated with Redlich−Kister type equations.

“…For heptane, the smallest deviation was obtained with data from Vijande et al [15]. In general, the heptane densities are slightly higher than those from literature, except for the data reported by Landaverde-Cortes et al [17]. For octane, the best agreement is found with the data reported in the TRC Tables [12].…”

“…This apparatus has been tested before with measurements of densities for nonane and decane and their binary mixtures [11]. Additionally, to check the performance of the VTD the densities of the pure compounds were compared with literature values [12][13][14][15][16][17][18][19][20][21][22][23][24].…”

Densities and Excess Molar Volumes of Alkane (Heptane, Octane, Nonane, or Decane) + Thiophene from T=293.15 to 313.15 K

Densities of four binary systems composed of an alkane (heptane, octane, nonane, or decane) and thiophene were measured at temperatures from 293.15 to 313.15 K at atmospheric pressure (0.7 atm). Measurements were made covering the full range of compositions for all systems studied and for the pure compounds by using a vibrating-tube densimeter (VTD). Excess molar volumes have been obtained from these experimental results and were fitted to a Redlich-Kister type expansion. The excess molar volumes exhibit positive deviations from ideal behavior for all of the binary systems studied here.

“…At higher temperatures, some fraction of MTBE may persist, decompose, and be used in oxidizing the soot before completing the combustion process inside the engine cylinder, which results in smaller amounts of soot [7]. MTBE has low viscosity and high volatility, characteristics which lead to enhanced mixing and production of a spray with droplets of small diameter [8].…”

Methyl tert-butyl ether (MTBE) was added to diesel fuel to investigate the effect on ignition delay and soot oxidative reactivity.An ignition quality tester (IQT) was used to study the ignition propensity of MTBE blended diesel fuels in a reactive spray environment. The IQT data showed that ignition delay increases linearly as the MTBE fraction increases in the fuel.A four-stroke single cylinder diesel engine was used to generate soot samples for a soot oxidation study. Soot samples were pre-treated using a tube furnace in a nitrogen environment to remove any soluble organic fractions and moisture content. Non-isothermal oxidation of soot samples was conducted using a thermogravimetric analyzer (TGA).It was observed that oxidation of 'MTBE soot' started began at a lower temperature and had higher reaction rate than 'diesel soot' across a range of temperatures. Several kinetic analyses including an isoconversional method and a combined model fitting method were carried out to evaluate kinetic parameters.The results showed that Diesel and MTBE soot samples had similar activation energy but the pre-exponential factor of MTBE soot was much higher than that of the Diesel soot. This may explain why MTBE soot was more reactive than Diesel soot.It is suggested that adding MTBE to diesel fuel is better for DPF regeneration since an MTBE blend can significantly influence the ignition characteristics and, consequently, the oxidative reactivity of soot.
