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.
