Attention has been given to possible adverse effects of incorporating tert-butyl methyl ether into antomobile fuels. tert-Butyl formate is an established product of photolysis, and it has been shown that photolysis in the presence of NO can produce the relatively stable tert-butoxyformyl peroxynitrate. This has a stability comparable to that of peroxy-acetyl nitrate, and may therefore increase the potential for disseminating NO (Kirchner et al. 1997).

These reaction pathways are in parallel with those for alkanes mentioned in Sect, 7.2.2, and the reactions (7.7, 7.8 and 7.9) after CH3 radicals are formed in reaction (7.43) are the same as those in the oxidation processes of methane described in Sect. 7.1. The specific feature of oxidation reactions of aldehydes is the formation of a metastable peroxy acyl nitrates from the reaction of peroxy acyl radicals with NO2 by reaction (7.41). In the case of acetaldehyde, peroxy acetyl nitrate, CH3C(0)00N02, is formed. This compound is called PAN (Peroxy Acetyl Nitrate), and is known to have much stronger toxicity to plants than ozone. A group of peroxy acyl nitrates are collectively called PANs. 

Like most radicals, this newly formed one is highly reactive, and almost immediately forms a bond to the oxygen molecules that surround and pepper it with collisions (Figure 24.4). The outcome is yet another radical. Lurking nearby we see an NO2 molecule, which is itself a radical. We see them collide and snap together to form the compound known as PAN, 4 (peroxy-acetyl nitrate). The chain of reactions ceases. PAN is highly soluble in water and moisture and is one of the principal eye irritants of photochemical smog.
