Vapour pressures of (butan-1-ol + hexane) at temperatures between 283.10 K and 323.12 K

Isothermal (vapour + liquid) equilibrium at several temperatures of (1-chlorobutane + 1-butanol, or 2-methyl-2-propanol)

“…The apparatus is similar to Marsh's (9) except for certain experimental details described elsewhere. (10,11) To prevent condensation effects on the mercury meniscus, the temperature of the manometer was maintained at 325 K by circulating water thermostatted to ±0.1 K. Likewise, most of the vapour phase was also maintained at T = 325 K. The temperature of the liquid sample was measured by a set of Beckmann thermometers, previously calibrated against the vapour pressure of benzene (Merck mole fraction >0.999), along with Ambrose's equation (12) relating temperature (T 68 ) with pressure by means of a sum of Chebyshev polynomials up to the sixth degree. The accuracy in the temperature was estimated to be ±0.01 K. The volume of the cell containing the liquid mixture was about 12 cm 3 , and (8 to 10) cm 3 were used in each experiment.…”

Vapour pressures at eight temperatures between 278.15 K and 323.15 K and excess molar enthalpies and volumes atT=298.15 K of (n-propylether+methanol)

“…The apparatus is similar to that of Marsh (10) except for experimental details which are described elsewhere. (11,12) To prevent condensation effects on the mercury meniscus, the temperature of the manometer was maintained constant by circulating water thermostatted at T = 325.0 K. Likewise, most of the vapour phase was also a To whom correspondence should be sent. maintained at T = 325.0 K. Manometric readings were made with a cathetometer to an accuracy of 20.01 mm, and the pressure reproducibility was estimated to be better than 15 Pa.…”

Excess functions atT= 298.15 K of (butanenitrile +methanol, +pentan-1-ol, +heptan-1-ol, +nonan-1-ol, or +decan-1-ol)

“…(4,5) The H E measurements were carried out with a calorimeter described elsewhere, (6) and V E was calculated from density measurements using a densimeter (Anton Paar DMA 60/DMA 602).…”
