The basic
structure for the PAN family is given above. In the simplest
|
|
PAN,
Peroxyacetyl nitrate, the R group is simply a CH3. For PPN, the R
|
|
group is a
propyl group, and so on. The
compounds were synthesized
|
|
from their
peracid precursors by adding concentrated nitric acid and a
|
|
small amount of
sulfuric acid as a catalyst. The
reaction took place in a
|
|
tridecane (heavy
lipid) solvent, and after it was completed it was washed
|
|
with water to
remove the excess acid. The organic
layer, containing the
|
|
PAN in
tridecane, was then frozen until needed.
For the Luminol and GC-
|
|
ECD analyses,
the PAN/tridecane solution was simply placed in a diffusion
|
tube at the air
inlet for each instrument. For IR
spectra, the PAN was
|
|
removed from the
tridecane by using a vacuum rack and placed in a gas
|
|
cell. The UV analysis was of the PAN/tridecane
solution.
