| Abstract |
A survey is presented of possible binary azeotropic systems suitable for study in an undergraduate physical chemistry laboratory. From a range of sources, a list has been compiled of the most acceptable systems on the basis of health, safety, waste disposal, and practicability concerns. More than 80 systems were reviewed. For comparison purposes, the list was reduced to a table showing 5 high-boiling and 19 low-boiling azeotropes with their exposure limits, approximate costs, and some physical properties of the mixtures. Comments are made about the strengths and weaknesses of the choice of each. The paper should supply the instructor with sufficient data to choose a binary system for study and with literature sources for further information.
