Volumetric Properties of Carbon Dioxide + Ethanol at 313.15 K

Abstract

Volumetric properties of carbon dioxide + ethanol mixtures at 313.15 K were measured, using the vibratingtube Anton Paar DMA 512P density meter. In the present experiments, no analytical instrument was required. The saturated pressures of carbon dioxide + ethanol mixtures at 313.15 K were measured by the synthetic method. The experimental data obtained were correlated with the density equation, the Soave-Redlich-Kwong (SRK) equation of state, and the pseudocubic equation of state.

Density Measurements of CO2-Expanded Liquids

“…For systems containing a one-phase liquid above the VLE region, density data are available for CO 2 + ethanol mixtures by Pöhler and Kiran at a temperature equal and higher than 323 K and molar fraction of CO 2 equal and higher than x = 0.5. Also, in the same one-phase liquid above the VLE region, density data of CO 2 + ethanol are available at 313 K and a pressure range of 1–10 MPa and at 312 K and higher temperatures in the range of 7.9–25 MPa . For another green solvent, ethyl lactate, there are no density data for one-phase liquid mixtures with CO 2 .…”

First Evidence of Solvent Spillage under Subcritical Conditions in Aerogel Production

“…Experimental data for the system CO 2 -ethanol from 19 sources − and a total of 146 experimental data points were collected. The data were used to determine the relative volume expansion of the system CO 2 -ethanol at different temperatures (291.15 to 343.15 K) and pressures (0 to 250 bar) using eq and are plotted in Figure . …”
