Radiochemistry Aims and scope

Abstract

The thermal stability of 2,6-pyridinedicarboxylic acid di(N-ethyl-4-fluoroanilide), 2,2'-bipyridine- 6,6'-dicarboxylic acid di(N-ethyl-4-ethylanilide), and 2,2'-bipyridine-6,6'-dicarboxylic acid di(N-ethyl-4- hexylanilide) at atmospheric pressure was studied. The course of their decomposition before and after saturation with nitric acid was compared to determine the influence of nitric acid on the thermal effects accompanying the oxidation of these substances.
