Viscosity is an important transport property for the optimum design of a chemical process plant and development molecular theories liquid state. A large amount experimental viscosity data has been produced all types liquids, from alternative refrigerants to molten salts metals. The accuracy these related operating conditions instrument and, this purpose as well calibration relative instruments, standard reference are necessary over wide range temperatures. New on toluene along saturation...
The transport properties of molten salts at high temperatures are crucial for the efficient design industrial equipment and chemical processes involving these materials. However, large discrepancies among data published by different authors laboratories still exist, mostly caused difficulties in accurate measurements. This situation with regard to thermal conductivity viscosity is especially serious plant design. aim this paper demonstrate implications uncertainty salt thermophysical...
Mutual diffusion coefficients for 2-(diethylamino)ethanol (2) in water (1) were experimentally obtained by the Taylor dispersion technique from x2 = 0 to ≈ 0.2, at T 298 K and 303 K. Viscosities surface tensions measured entire composition range using capillary viscometry ring tensiometry, respectively. above temperatures, intervals of 5 temperature (283 303) Information about intermolecular interactions, hydration modes, solute aggregation is provided through combined study observed changes...
Viscosity is one of the most important properties for many technological and scientific applications, therefore it has been subject an enormous effort measurement, correlation, interpretation. This completely inconsistent with fact that probably fluid property less independent reference values can be used by everyday users as guidance, calibration, or designing tools. The only accepted standard, viscosity pure water at 20 °C, unsatisfactory because among different fluids vary a factor 1014....
Ionic liquids have proved to be excellent heat transfer fluids and alternatives common HTFs used in industry for exchangers other equipment. However, its industrial utilization depends on the cost/kg of production, competitive applications with biphenyl diphenyl oxide, alkylated aromatics, dimethyl polysiloxane oils, which degrade above 200 °C possess some environmental problems. The efficiency as a fluid fundamental thermophysical properties necessary model convective (density, capacity,...
Published data on the thermophysical properties of ionic liquids are normally in disagreement if results from different laboratories, using samples and measurement protocols, compared. This fact was recognized years ago at level International Union Pure Applied Chemistry (IUPAC), which established IUPAC Project 2002-005-1-100 (Thermodynamics liquids, liquid mixtures, development standardized systems), with main objective recommending a reference liquid, making reference-quality measurements...
Ionic liquids with the dicyanamide anion, namely, 1-alkyl-imidazolium cations, have been receiving attention recently due to their potential applications. The utilization of these as heat transfer fluids, specifically in small exchangers and microchannels for microprocessor cooling, is presently deemed highly feasible, it can be both more efficient environmentally acceptable. design a equipment that makes use fluids requires knowledge thermophysical properties. In this regard, dispersions...
Thermophysical properties of 1-butyl-3-methylimidazoliumtris(pentafluoroethyl) trifluorophosphate, [C4mim][(C2F5)3PF3] (CAS RN 917762-91-5) ionic liquid, were measured in the temperature range T = (283.15–353.15) K, at P 0.1 MPa. These include density, isobaric heat capacity, speed sound, refractive index, viscosity, and thermal conductivity their correlation as a function temperature. Data obtained compared with available literature, whenever available. Comparison these results those...
