The influence of water-miscible alcohols (methanol, 1-propanol, 2-propanol, and t-butyl alcohol) on the isomerization of glucose to fructose and mannose was investigated under subcritical aqueous conditions (180–200 °C). Primary and secondary alcohols promoted the conversion and isomerization of glucose to afford fructose and mannose with high and low selectivity, respectively. On the other hand, the decomposition (side-reaction) of glucose was suppressed in the presence of the primary and secondary alcohols compared with that in subcritical water. The yield of fructose increased with increasing concentration of the primary and secondary alcohols, and the species of the primary and secondary alcohols tested had little effect on the isomerization behavior of glucose. In contrast, the isomerization of glucose was suppressed in subcritical aqueous t-butyl alcohol. Both the conversion of glucose and the yield of fructose decreased with increasing concentration of t-butyl alcohol. In addition, mannose was not detected in reactions using subcritical aqueous t-butyl alcohol.

“…Density of the geothermal fluid samples was measured with three different commercial instruments (Anton Paar DMA 4500, SVM 3000, and DSA 5000M). Usually, the temperature and pressure dependencies of the parameters A and B in the working equation of the VTD apparatus are determined using the calibration procedures (see details in refs − ) with a minimum of two reference fluids such as water, air, nitrogen, benzene, and toluene whose PVT properties are well-known (REFPROP) and should be performed very carefully. The accuracy of the method is limited by the calibration procedure and depends on the uncertainty of the properties of calibrating fluid.…”

“…The repeatability of density and temperature measurements are 0.01 kg·m –3 and 0.01 K, respectively. This VTD has been successfully used previously in our earlier publications − to get an accurate measure of the density of various fluids (ionic liquids, hydrocarbons, and their mixtures with alcohols − , ). During the oscillation of the U-tube, the sample shows the effect of damping of the oscillation, which is a function of the sample viscosity.…”

Volumetric (density), acoustic (speed of sound), and transport (viscosity) properties of natural geothermal fluids from south Russia Geothermal Field have been measured over the temperature range from (278 to 343) K and at atmospheric pressure. The measurements were made using the Anton Paar DMA4500 densimeter and Stabinger SVM3000 viscometer for four geothermal fluid samples from the hot-wells. A sound-speed analyzer (Anton Paar DSA 5000 M) was used to measure the speed of sound and the density of the same geothermal samples. The combined expanded uncertainty of the density, viscosity, and speed of sound measurements at the 95% confidence level with a coverage factor of k = 2 is estimated to be as follows: density, 0.0005% (for DMA 4500), 0.02%, or 0.5 kg•m −3 (for the SVM 3000 viscodensimeter) and 0.01% (for the DSA 5000 M sound-speed analyzer); viscosity, 0.35% (for SVM 3000); and speed of sound, 0.1% (DSA 5000 M). Measured values of density and speed of sound were used to calculate other very important derived thermodynamic properties of the geothermal fluid samples. Measured values of density, viscosity, and speed of sound were used to develop correlation models which reproduced the measured values of density, viscosity, and speed of sound within 0.03%, 2.55%, and 0.06%, respectively. The measured properties at atmospheric pressure have been used as reference values for the prediction of high pressure properties.

“…Wu et al 33 reported P-V-T relationships for three hydrocarbons: hexadecane, octadecane and eicosane over the temperature range 323 to 523 K and for pressures up to 265 MPa. Abdulagatov et al 34 determined the saturated liquid density for 1-propanol over the temperature range 298 to 423 K from compressed liquid density and saturated vapour pressure data. In the restricted region near the critical point, Rasulov et al 35 measured the saturated liquid density for 1-butanol.…”

The vapour-liquid equilibrium of pure liquids and of their mixtures, together with the saturated liquid densities, constitute important thermodynamic properties in the understanding of matter. As a consequence, research into saturated liquid densities of operating fluids is very active and many papers have reported on pure saturated liquid densities and on the densities of mixtures. These experimental results have been fitted by empirical equations like the Tait equation, 1 and various kinds of equations of state. A summary of the research on the equilibrium properties of fluids is described by Poling et al. 2 In our previous studies, the saturated liquid density and related properties were widely investigated for pure liquids and mixtures and the data were utilised for the estimation of other physical properties and process design like heat pumps and refrigerators. [2][3][4][5][6][7][8][9][10][11][12][13][14][15][16] In this chapter, we describe the latest experimental research and trends in saturated liquid densities of pure liquids and of liquid mixtures. Furthermore, the equations of state used to estimate saturated liquid density estimations are reviewed.Volume Properties: Liquids, Solutions and Vapours Edited by Emmerich Wilhelm and Trevor M.
