Densities, Viscosities, Refractive Indices, and Surface Tensions for the Mixtures of 1,3-Dioxolane + 2-Propanol or + 2,2,4-Trimethylpentane at (288.15, 298.15, and 308.15) K and 1,3-Dioxolane + 2-Propanol + 2,2,4-Trimethylpentane at 298.15 K

Abstract

Densities, viscosities, refractive indices, and surface tensions of a ternary system (1,3-dioxolane + 2-propanol + 2,2,4-trimethylpentane) at T = 298.15 K and two binary systems (1,3-dioxolane + 2-propanol and 1,3-dioxolane + 2,2,4-trimethylpentane) at T = (288.15, 298.15, and 308.15) K were measured over the extensive composition range at atmospheric pressure. Densities were determined using a vibrating-tube densimeter. Viscosities were measured with an automatic microviscometer based on the rolling-ball principle. Refractive indices were measured using a digital Abbe-type refractometer. Surface tensions were determined by the Wilhelmy-plate method. The excess molar volumes V E were calculated from the experimental density data. The results are discussed in terms of molecular interactions.

Density, Viscosity, Speed of Sound, Bulk Modulus, and Surface Tension of Binary Mixtures of n-Heptane + 2,2,4-Trimethylpentane at (293.15 to 338.15) K and 0.1 MPa

“…The surface tension values are given in Table for the mixtures studied herein as a function of the mole fraction of 2,2,4-trimethylpentane, X 1 . A linear regression of surface tension versus temperature data found in the literature − for 2,2,4-trimethylpentane yields the following relationship: that is shown in Figure . This equation predicts that the value of surface tension at 294.4 K should be 18.7 mN·m –2 , which agrees with the data reported herein of 18.7 ± 0.3 mN·m –2 .…”

“…1,2 Oxygenated liquids are generally added to gasoline to improve octane number and reduce pollution. 3 o-Chlorotoluene is used in the production of chlorobenzyl chloride, 2-chlorobenzaldehyde, and 2-chlorobenzoic acid which in turn are used as precursors in the production of optical brighteners, dyes, pharmaceuticals, and fungicides. 4 Any process like simulation of the synthesis, purification, or gasoline blending, prior to the design stage needs a thermodynamic model for the description of the physical behavior.…”
