“…According to the present results, the critical parameters of DEE differ from the data reported by Kobe and Lynn [68] within 0.305 K, 2.17 kPa, and 1.1 kg · m −3 . The present critical density is in fair agreement (within 1.5 %) with other studies [17,19,20,25,[93][94][95][96], while there is good (0.06 %, maximum 0.14 %) agreement for the critical pressure with the data reported by [19,23,32,31,33,68,58,96].…”

“…[26]; ×- [28] point, the deviations increase to 2.0 % to 2.5 % for the pressure due to differences in the value of the critical pressure, while for the saturated densities, the agreement between the present data and those calculated from correlations are within 1.3 % to 2.0 % in the critical region. Our saturated-density measurements are in reasonable agreement with those calculated from the correlation by Hales et al [25], i.e., within 0.25 % (maximum deviation is 0.3 %). Acceptable deviations within 2 % were found with the other reported and calculated data in the immediate vicinity of the critical temperature.…”

The isochoric heat capacities C V 1 , C V 1 , C V 2 , C V 2 , saturation densities (ρ S and ρ S ), vapor pressures (P S ), thermal-pressure coefficients γ V = (∂ P/∂ T ) V , and first temperature derivatives of the vapor pressure γ S = (dP S /dT ) of diethyl ether (DEE) on the liquid-gas coexistence curve near the critical point have been measured with a high-temperature and high-pressure nearly constant-volume adiabatic piezocalorimeter. The measurements of (C V 1 , C V 1 , C V 2 , C V 2 ) were made in the liquid and vapor one-and two-phase regions along the coexistence curve. The calorimeter was additionally supplied with a calibrated extensometer to accurately and simultaneously measure the PVT , C V VT , and thermal-pressure coefficient, γ V , along the saturation curve. The measurements were carried out in the temperature range from 416 K to 466.845 K (the critical temperature) for 17 liquid and vapor densities from 212.6 kg · m −3 to 534.6 kg · m −3 . The quasi-static thermo-(reading of PRT, T − τ 123 560 Int J Thermophys (2011) 32:559-595 plot) and baro-gram (readings of the tensotransducer, P − τ plot) techniques were used to accurately measure the phase-transition parameters (P S , ρ S , T S ) and γ V . The total experimental uncertainty of density (ρ S ), pressure (P S ), temperature (T S ), isochoric heat capacities (C V 1 , C V 1 , C V 2 , C V 2 ), and thermal-pressure coefficient, γ V , were estimated to be 0.02 % to 0.05 %, 0.05 %, 15 mK, 2 % to 3 %, and 0.12 % to 1.5 %, respectively. The measured values of saturated caloric C V 1 , C V 1 , C V 2 , C V 2 and saturated thermal (P S , ρ S , T S ) properties were used to calculate other derived thermodynamic properties C P , C S , W, K T , P int , H vap , and (∂ V /∂ T ) P of DEE near the critical point. The second temperature derivatives of the vapor pressure, d 2 P S /dT 2 , and chemical potential, d 2 μ/dT 2 , were also calculated directly from the measured one-and two-phase liquid and vapor isochoric heat capacities (C V 1 , C V 1 , C V 2 , C V 2 ) near the critical point. The derived values of d 2 P S /dT 2 from calorimetric measurements were compared with values calculated from vapor-pressure equations. The measured and derived thermodynamic properties of DEE near the critical point were interpreted in terms of the "complete scaling" theory of critical phenomena. In particular, the effect of a Yang-Yang anomaly of strength R μ on the coexistence-curve diameter behavior near the critical point was studied. Extended scaling-type equations for the measured properties P S (T ), ρ S (T ), and (C V 1 , C V 1 , C V 2 , C V 2 ) as a function of temperature were developed.

Acetic acid, CH 3 COOH, is a corrosive organic acid having a sharp odor, burning taste, and pernicious blistering properties. It is found in ocean water, oilfield brines, rain, and at trace concentrations in many plant and animal liquids, and has a place in organic processes comparable to sulfuric acid in the mineral chemical industries. It is central to all biological energy pathways. Fermentation of fruit and vegetable juices yields 2–12% acetic acid solutions, usually called vinegar. Uses include the manufacture of vinyl acetate and acetic anhydride. Vinyl acetate is used to make latex emulsion resins for paints and adhesives. Acetic anhydride is used in making cellulose acetate fibers and cellulosic plastics. About half of the world production comes from methanol carbonylation and about one‐third from acetaldehyde oxidation. Glacial acetic acid is dangerous, but its precise toxic dose is not known for humans. Vinegar, on the other hand, which is dilute acetic acid, has been used in foods and beverages since ancient times.
