Altering Elemental Composition of Spectrally Matched Flare Fuels

摘要

There is an increasing emphasis on the production of specific emitters from the combustion of spectrallymatched organic spectral fuels. In this paper we examine a change in elemental composition of the fuelrather than rely on changes to formulation recipes to achieve spectral matching. We reasoned that achange in elemental composition of the spectral fuel offered a higher degree of control over formulationvariations.Specifically, we have examined the incorporation of boron into the fuels, an element which has shownconsiderable promise for production of specific emitters. This has been achieved by utilising smallaromatic heterocycles able to form complexes with boron. We will report on the synthesis, and initialcharacterisation of several of these derivatives.
