An introduction to the problem of critical pressure calculations of mixtures is presented, followed by a brief history of prior work in this field. Mentioned in the history are the correlations of Watson and Nelson, Smith and Watson, Mayfield, Kuratta and Katz, Benedict, and Edmister. Another section contains a series of tables showing critical pressure calculated by Benedict's equation as contrasted to other data appearing in the literature. An evaluation of the equation is then made from the comparisons.

Included are curves of the values shown in the tables end a series of curves depicting the deviation of these values from the experimental.
