This paper presents a method of calculating the van Laar constants for binary vapor‐liquid systems. The basis of the method is the van Arkel modification of the van Laar (Scatchard‐Hildebrand) equations which utilize the concept of internal pressure. A generalized method of predicting the apparent internal pressure was developed and described. The experimental van Laar constants and those calculated by the proposed method are compared for twelve polar‐nonpolar binary systems.
