Liquid-Liquid Solubilities for the Binary Systems of Methanol with Octane and 2,2,4-Trimethylpentane.

Determination and correlation of liquid–liquid equilibria for four binary N,N-dimethylformamide+hydrocarbon systems

“…Here, the mutual solubility curves for 23 binary systems, including eight alcohol + hydrocarbon systems [6][7][8]10], two alcohol + water systems [1,3], eight high-viscosity binary systems [2,4,8,9], and two systems containing polystyrene, have been measured using this technique [5]. The present work is a continuation of our previous studies.…”

Flash-point prediction for binary partially miscible mixtures of flammable solvents

“…The liquid-phase activity coefficients for these five mixtures were estimated using the NRTL [19] and T-K-Wilson equations [21], with parameters adopted from the literature [7,8,27] ( Table 2). The parameters used for calculating the liquid molar volumes required for the T-K-Wilson equation…”

“…(also obtained from the literature [7,8]) are listed in Table 3. The Antoine coefficients were also sourced from the literature [18] ( Table 4).…”

“…Since the cost of flash-point data derived from test instruments is very expensive in Taiwan (NT$20,000/US$600 per sample), a model for predicting the flash point of a given mixture is useful. Partially miscible mixtures are used in liquid-liquid extraction processes [7,8]. The flash-point value for a given substance is relative to its vapor pressure [2].…”

“…However, to our knowledge no applicable model has been available for partially miscible mixtures. In this manuscript, a model for such mixtures was developed and investigated using the partially miscible mixtures: methanol + octane; methanol + decane; acetone + decane; methanol + 2,2,4-trimethylpentane; and, ethanol + tetradecane [7,8].…”
