Introduction
This 
  experiment 
  is 
  essentially 
  Shoemaker’s 
  Experiment 14: Binary 
  Liquid-‐Vapor 
  Phase 
  Diagram
(1). 
   Two 
  significant 
  modifications 
  to 
  this 
  experiment 
  have 
  been 
  made. 
   
  The 
  cyclohexane/ethyl 
  acetate 
  
system 
  is 
  studied, 
  as 
  described 
  by 
  Gordon, 
  Kenkel, 
  Prescia 
  and 
  Towns (4). 
   
  A 
  refluxing 
  method 
  is 
  used, 
  as 
  
described 
  in 
  the 
  article 
  by 
  James 
  W. 
  Rogers 
  and 
  co-‐authors (5). 
   
  The 
  two 
  component 
  system 
  that 
  we 
  use 
  
will 
  exhibit 
  a 
  strong 
  positive 
  deviation 
  from 
  Raoult’s 
  law, 
  resulting 
  in 
  a 
  boiling 
  point 
  minimum.
