An Excursion into Phase Tetrahedra-Where Physical Chemistry and Geometry Meet

摘要: Phase diagrams are effective means of graphically representing the phase behavior single and multicomponent systems. In many undergraduate chemistry curricula students will be introduced to mainly single- two-component systems in form x-y graphs. Although treated some standard texts, three- four-component less commonly encountered by students. Moreover, procedure described here is more detailed than procedures textbooks.In this article we show how ternary (three-component) quaternary (four-component) can represented as triangles tetrahedra. particular, discuss a system composed oil, water, surface-active agent (surfactant), cosurfactant. It shown that although fully tetrahedron, it convenient display two-dimensional representations given slices cut through tetrahedron. Of infinite number resulting triangular...
