BOILlNG . POINT - COMPOSITION DIAGRAM OF THE SYSTEM DIOXANE - WATER By Edgar

چکیده
Dioxane and water form a positive homoazeotrope which has an azeotropic decrease in temperature sufficiently large to effect the complete r emoval, by fractional distillation through an efficient column, of water present as an impurity. The boiling-point-composition diagram, including the composition of the vapor in equilibrium with the boiling liquid, was determined. The normal boiling point of dioxane was found to be 101.320° C.

Studying lithium-ion battery packs cooling system using water-nanofluids composition
In this study, the Li-ion batteries temperature increase during the discharge process was measured empirically and evaluated using numerical simulation. Moreover, the battery packs cooling using the water, air and water-nano composition fluids such as water-alumina, water-copper oxide, and water-gold was studied through numerical simulation. Accordingly, the battery cooling was simulated by CFD...
متن کاملDynamical structure of water in dioxane aqueous solution by low-frequency Raman scattering
The low-frequency Raman spectra of dioxane aqueous solutions have been analyzed from a dynamical aspect of water structure. The reduced Raman spectra x9( n̄) of the dioxane aqueous solutions are well explained by a superposition of three characteristic modes of water and one Gaussian mode ~;60 cm! of dioxane. The concentration dependence of x9( n̄) spectra shows that the 190 cm mode of water disa...

Isothermal phase diagrams for the semicrystalline poly-L-lactide (PLLA) and the amorphous poly-DL-lactide (PDLLA) in combination with several solvent-nonsolvent combinations (dioxane/water, dioxane/methanol, chloroform/methanol, and NMP/water) have been determined. The locations of the liquid-liquid miscibility gap, the solid-liquid miscibility gap and the vitrification boundary in the isotherm...
متن کاملPhysico-chemical evaluation of a biocompatible microemulsion system containing IPM/Tween80/Isobutanol
A biocompatible microemulsion system comprising of isopropyl myristate (IPM) as oil, tween 80 as a non-ionic surfactant and isobuthanol as co-surfactant was studied experimentally at 298.15 K. The pseudo-ternary phase diagram for the microemulsion system has been delineated at different surfactant to co-surfactant mass ratio of 1:1, 2.4:1 and 4:1. Some physico-chemical properties such as densit...
متن کاملPhase Equilibria of the Ternary System Water + Phosphoric Acid + 1-Nonanol at Different Temperatures
The purpose of this reaserch is to measure the phase equilibrium data of the ternary system (water + phosphoric acid + 1-nonanol) at different temperatures. Experimental solubility curves and tie-line points for the system were obtained at T = 298.2, 308.2 and 318.2 K and ambient pressure. The binodal curve data were detected by the cloud point method. The mass fractions of each layer ...
