The Ignition Behavior of Various Amines With White Fuming Nitric Acid

Abstract

Spontaneous ignitibil ity depends on synergetic behavior of several reactions, each of which exerts its greatest independent influence at a different t ime during the ignit ion period. The m o s t important of these reactions are a l iquid phase neutral izat ion reaction for al iphatic amines , a l iquid phase ni trat ion reaction for aromatic amines , and a slower, rate determining oxidation reaction which follows the others. Mixing which is too rapid can quench ignit ion if the mixture ratios, favoring the various reactions leading to ignit ion, are too widely separated.
