Abstract
Isothermal pressure-composition VLE data have been measured for
four systems containing acetic acid and a gaseous component. The
gaseous components are carbon monoxide, carbon dioxide, hydrogen
and methane. The measurements were made in a static cell and the
compositions of the gas and the liquid phases were measured by a
gas chromatograph.A new model (ACE, Association + Cubic Equation
of state) was developed. It is based on a cubic equation of state
and a model for the dimerization of acetic acid. It was applied to
correlate the experimental VLE data with good results.
