The Significance of Emission from Excited Formaldehyde in Premixed Flames of Some Hydrocarbons and Perchloric Acid.

Abstract

The 'cool flame' emission from excited formaldehyde is premixed flames of perchloric acid (72%) and methane, or a fuel which produces methane in the flame, is attributed to a reaction between the CH3 radical and ClO3, ClO2 or ClO. The yield of light quanta emitted by NCHO(*) per molecule of methane consumed has been measured. Although this reaction does not constitute a step in the main mechanism of the combustion the emission could, in principle, be used to indicate the proportion of fuel in a composite propellant based on ammonium perchlorate and polyisobutene which reacts with chlorine-oxygen compounds.
