An empirical method has been developed for the prediction of vapor‐liquid equilibrium data, both composition and temperature, for a series of binaries of chain hydrocarbons with carbon tetrachloride. The maximum and absolute average deviations in vapor composition are 0.035 and 0.006 mole fraction, respectively, and in temperature are 1.5 and 0.4°C, respectively. Because of assumptions inherent in the theory, the prediction (as opposed to correlation) tends to apply only with chain compounds and not with compounds containing rings. Systems containing cyclic and aromatic hydrocarbon compounds, however, have been correlated by this method with some degree of success.
