Rmm. Stevens et al., HIGH-PRESSURE VAPOR-LIQUID-EQUILIBRIA OF THE TERNARY-SYSTEM CARBON-DIOXIDE PLUS VINYL-ACETATE PLUS 2-BUTANOL - EXPERIMENTAL AND MODELING RESULTS, Journal of chemical and engineering data, 42(6), 1997, pp. 1280-1284
Bubble-point and dew-point pressures and vapor-liquid critical points
of the ternary system (x(1))carbon dioxide +(x(2))vinyl acetate +(x(3)
)2-butanol were measured in the temperature range 278-510 K up to 14 h
lPa in a high-pressure capillary glass tube apparatus, using the synth
etic method. The system has been investigated for varying carbon dioxi
de compositions at fixed ratios of vinyl acetate and 2-butanol (x(2)/x
(3) = 1/3 and 3/1) and at fixed 2-butanol composition (x(3) = 0.15). M
odeling of the vapor-liquid equilibria of the ternary system has been
performed using tyro equation of state (EOS) methods: (1) the Stryjek-
Vera modification of the Peng-Robinson EOS with the Wong-Sandler mixin
g rules (PRSV/WS) implementing the NRTL-G(E) model; (2) the LCVM model
, which is the translated modified PR EOS with the linear combination
of Vidal and Michelsen mixing rules implementing the UNIFAC-GE model.
