Understanding Ternary Phase Diagrams for Inverted Micelle Formation

Click For Summary
SUMMARY

The discussion focuses on interpreting ternary phase diagrams specifically for inverted micelle formation, highlighting a composition of 9% NaC(8), 28% water, and 63% C(10)OH. To determine this composition, one must draw three lines parallel to the axis opposite the vertex of the substance of interest, which in this case is C(10)OH. The diagram's axes represent C(10)OH on the left, H2O on the right, and NaC(8) at the bottom, guiding users in understanding the conditions necessary for micelle formation.

PREREQUISITES
  • Ternary phase diagrams
  • Inverted micelle formation
  • Composition analysis in chemical systems
  • Basic understanding of surfactants and their properties
NEXT STEPS
  • Study the principles of ternary phase diagrams in detail
  • Research the role of surfactants in micelle formation
  • Explore experimental methods for determining compositions in phase diagrams
  • Learn about the applications of inverted micelles in various chemical processes
USEFUL FOR

Chemists, materials scientists, and students studying surfactant behavior and phase diagrams will benefit from this discussion.

Will someone please explain how one can read from this diagram that the composition is 9% NaC(8), 28% water and 63% C(10)OH when we have the smallest amount of C(10)OH to have inverted micelles in the system?

I believe you have to draw three lines, parallel to the axis opposite the vertex of the substance you are interested and going through the point in question. Here since you are interested in inverse micelle and lowest composition in C10OH it responds to the area i marked.

The left axis is C10OH , right is H2O and the bottom is NaC8.

P.S. I just googled it tbh, never seen a diagram like that before and it seemed interesting. So i might as well be wrong. You can read about it http://www.sv.vt.edu/classes/MSE2094_NoteBook/96ClassProj/experimental/ternary2.html" .
