Binary phase diagrams of some alcohols were developed and IR studies have been made in hexadecanol‐octadecanol system to identify the phases. When the components differ by no more than two carbon atoms, their freezing point curves show solid solution type behavior with peaks occurring at some significant compositions. The occurrence of such peaks is considered to be indicative of molecular complex formation between the components. Alcohols mix properly with each other in their high temperature form, which is not always the case with their lower temperature modifications. The reason is attributed to the nature of the high temperature forms of alcohols. This allows effective mixing between the components to take place. IR studies are found to be quite useful in phase identification in these systems.
