Since the prediction of the Joule-Thomson inversion curve is known as a sever test of the equation of state, five recent equations of state of van der Waals type are tested for their ability to predict the Joule-Thomson inversion curve. These five equations are : Adachi-Lu-Sugie, Kubic-Martin, Yu-Lu, Twu-Coon-Cunningham, and Deiters equation of state. The investigated equations of state give good prediction of the low-temperature branch of the inversion curve, except for Yu-Lu equation of state. Generally, the high-temperature branch and the peak of the inversion curve proved to be sensitive to the applied equation of state. The results indicate that Deiters equation of state provided the most accurate prediction of the date in the sensitive regions.
