Peroxyacetyl Nitrate

Peroxyacetyl Nitrate. Peroxyacetyl nitrate (PAN) The best known member of a class of photochemical oxidizing agents known as the peroxyacyl nitrates The peroxyacyl nitrates are formed when ozone reacts with hydrocarbons such as those found in unburned petroleum They are commonly found in photochemical smog The peroyxacyl nitrates attack plants causing spotting and discoloration of leaves destruction of flowers reduction in fruit production and seed formation and death of the plant.

Peroxyacetyl nitrate is an unstable highly oxygenated compound that exists only in the atmosphere It is a key intermediate in the formation of the air pollutant ozone In December 2019 Emily V Fischer at Colorado State University (Fort Collins) was awarded the James B Macelwane Medal at the fall meeting of the American Geophysical Union.

Peroxyacetyl nitrate (PAN CH 3 C(O)OONO 2) is an important constituent of photochemical smog It is also a ubiquitous chemical present throughout the global troposphere A unique property of PAN is that it is very stable at cold temperatures and easily decomposes to release NO x at warm temperatures.
