Distillation and Column Chromatography
1.
column
chromatography
is
a:
purification
technique
used
to
isolate
compounds
from
a
mixture
2.
Boiling
point
is
the
temperature
at
which:
a liquid changes into
vapor due to
the fact that the
vapor pressure of the liquid equals the pressure surrounding the liquid
3.
What
does
BP
depend
on?:
intrinsic
forces
such
as
molecular
weight
,
structure,
intermolecular
forces
4.
Objective
of
this
experiment:
Separate and
purify a mixture
of
essential oils, Purify
a compound using
vacuum
distillation,
Purify
a
compound
using
vacuum
flash
chromatography,
Identify
unknowns
based
on
GCMS
5.
Distillation
is a purification method that allows
:
separation of a
liquid from a mixture based on the difference among the individual BP of the mixture components.
6. When setting up distillation experiments it is
important to remember the closer the BP, the is the path that the vapors have to
travel before they are collected upon condensation.: longer
7. What would happen if 400 mesh silica gel was used for a gravity column?: The
solvent
will
pass
through
the
column
too
slowly.
