While the relative importance of the various paths is not well established, it is expected that dissociation to the alkoxy radical, RO, and N02 will predominate. Luke et al. (1989) experimentally measured rates of photolysis of simple alkyl nitrates and compared them to rates calculated using the procedures outlined in Chapter 3.C.2. Figure 4.22 compares the experimentally determined values of the photolysis rate constants (kp) for ethyl and n-propyl nitrate with the values calculated assuming a quantum yield for photodissociation of unity. The good agreement suggests that the quantum yield for photodissociation of the alkyl nitrates indeed approaches 1.0.

Of the simple alkyl nitrates, methyl nitrate is present in the highest concentration. For example, in measurements made in Schauinsland, a rural area in Germany, concentrations of CH30N02 up to 216 ppt were measured. The median value, however, was only 19 ppt (Flocke et al., 1998). In the same studies, the median concentrations for ethyl nitrate, n-propyl nitrate, 2-pro-pyl nitrate, and 1-butyl nitrate were 9, 3, 12, and 2 ppt, respectively. The sum of the C,-C8 alkyl nitrates averaged 120 ppt, which is only 3% of the NO. Similarly, in rural Ontario, Canada, 17 different organic nitrates were identified in air, but their sum was only 0.5-3% of NOj. (O Brien et al., 1995). In aircraft measurements over the Pacific Ocean near Hawaii, average values for methyl nitrate near the surface were 6 ppt and the sum of C,-C5 alkyl nitrates was <5% of the total NO, (Ridley et al., 1997).

Aminoferrocene (XXXV) can be prepared in low yield by treatment of O-methylhydroxylamine or O-benzylhydroxylamine with ferrocenyllithium (1, 65). Nitroferrocene (XXXVI), unattainable by direct nitration of ferrocene, can be isolated from the reaction of ferrocenyllithium and either n-propyl nitrate or dinitrogen tetroxide at —70° (30, 36). A similar reaction between ferrocenyllithium and nitrous oxide leads to azoferrocene (XXXVII) (08). 

Vanta et al (Ref 2) determined the detonation limits of propylene oxide/air mixts to be 2.7 to 14.4 volume %, or much narrower than the flammability limits of ethylene oxide/air (see Table 3). They also measured the lower detonation limit for n-propyl nitrate/air and found it to be 2.2 volume %...
