Local decomposition

This and the 4-bromo-2,6-dinitro analogue show local decomposition on moderate heating. 

The solid amine can be caused to detonate by heating, or by a powerful initiating charge, and fast local decomposition occurs on heating moderately. 

A violent explosion in an ammonium nitrate store with sawdust-covered floors (to absorb spillage and prevent sparks) was attributed to local decomposition of the moist nitrate-containing sawdust, leading to temperature rise and spontaneous ignition. The observation of red-brown fumes just before the explosion supports this hypothesis.

In a process for preparation of 2-methoxy-5-nitroaniline the anisidine salt was added to stirred sulfuric acid. An accidental deficiency of the latter prevented proper mixing and dissipation of the heat of solution, and local decomposition spread through the entire content of the 2000 1 vessel, attaining red heat. 

This process is further illustrated by the plots in Fig. 4.15(b) where the moan dorusity J> of thermodynamically stable confined pha.ses is plotted as a function of z (i.c., the pore width). Three different branches arc discernible. For small z < 8, p is relatively high indicating that the pore is filled with liquid. A corresponding plot of the local densities of a representative phase for z = 5 shows that this liquid consists locally of A- (or B-)rich, high-density fluid (because the two cannot be distinguished in a symmetric mixture). Hence, for 2 < 8, we observe (local) decomposition of liquid mixtures. 

Rhodamine 6G in an ionically conducting polymer were formed as a result of the local decomposition of the quencher, methyl viologen. The latter was incorporated inside the film with the dye and quenched the fluorescence of the Rhodamine 6G. However, when a tungsten tip biased at -4 V versus the platinum substrate was scanned at 1 /xm- s the quencher was decomposed, probably due to its reaction with hydroxyl ions that were generated at the tip, and the fluorescence of the dye was recovered. The authors concluded that the factors governing the resolution of the patterns were the...

With the single-channel and strong orthogonality condition imposed on the continuum electron orbital, a many-body factor is obtained that is only dependent on the characteristics of the residual bound states. A conventional MO analysis of the spectra is entailed only if there is just one large many-body term in the summation and if that term is close to 1. In that case one further reduces the MO factor in terms of, for example, local decomposition of symmetries and charges. One notes that for Auger a continuum orbital enters explicitly in the MO factor (as it does also in the photoionization case) the calculation of the MO factor will be discussed in a following section.
