Bubble Point Measurements of Neopentane + Ethane Mixtures
Elisabeth Mansfield, Vladimir Diky
Bubble point measurements have been taken on three compositions of neopentane + ethane systems. The results are modeled with a Peng-Robinson equation with symmetrical mixing rule and a Helmholtz-energy based 4-parameter model. Interaction parameters for all fits are provided. The results are consistent with other similar mixture systems (neopentane + propane and ethane + propane) and demonstrate near ideal mixing.
