(VAPOR PLUS LIQUID) EQUILIBRIA OF (ALKOXYALKANES PLUS ALKANES, OR O-XYLENE, OR WATER, OR METHANOL) FOR ETHER MOLE FRACTIONS 0 TO 0.5, BETWEEN TEMPERATURES 293-K AND 323-K
Aq. Clark et al., (VAPOR PLUS LIQUID) EQUILIBRIA OF (ALKOXYALKANES PLUS ALKANES, OR O-XYLENE, OR WATER, OR METHANOL) FOR ETHER MOLE FRACTIONS 0 TO 0.5, BETWEEN TEMPERATURES 293-K AND 323-K, Journal of Chemical Thermodynamics, 29(4), 1997, pp. 441-446
Modern environmentally beneficial methods of formulating motor gasolin
e often use ethers and/or alcohols as octane improvers. Thus, the ther
mophysical properties of these substances have become important in pro
cess engineering design, the simulation of gasoline blending operation
s, and engine operability. In all of these applications phase equilibr
ium properties are represented by thermodynamic models, which are deri
ved from a combination of theory and experimental phase equilibrium da
ta. This work seeks to quantify these models by careful measurement of
key thermodynamic properties. For that purpose (vapour + liquid) equi
librium measurements on 2-methoxy-2-methylpropane, 2-ethoxy-2-methylpr
opane, and 2-methoxy-2-methylbutane with various alkanes, o-xylene, me
thanol, and water have been made using a static experimental method, a
t ether mole fractions of x = 0 to x = 0.5 over a temperature range of
293 K to 323 K. (C) 1997 Academic Press Limited.
