Abstract
Vapour‐liquid equilibria in binary systems of ethylene with n‐eicosane, n‐hexacosane and n‐tetracontane have been measured in the temperature range 325 to 450 K and at pressures up to 40 MPa. The results show a distinct influence of the molecular weight of the n‐alkanes on these equilibria especially in the critical region. Except for the critical region the fluid phase equilibria in this kind of systems can be represented reasonably well using the Peng‐Robinson equation of state with temperature dependent pure component parameters a and b and two binary interaction parameters.Keywords
