High pressure vapour-liquid equilibria in binary mixtures of carbon dioxide and benzaldehyde, bromobenzene, chlorobenzene, 1,2-dichlorobenzene and 2-chloro-1-methylbenzene at temperatures between 313 and 393 k and pressures up to 22 MPa

The high-pressure vapour-liquid equilibrium in binary mixtures of carbon dioxide and five aromatic compounds (benzaldehyde, bromobenzene, chlorobenzene, 1,2-dichlorobenzene and 2-chloro-1-methyl-benzene) has been investigated by a flow technique at temperatures between 313 and 393 K at pressures up to about 22 MPa. For none of these mixtures – with the exception of CO₂ + benzaldehyde – experimental results have been reported before. The experimental arrangement is described. The results of the measurements are reported, discussed and correlated by a recently developed generalized Bender equation of state.
