Thermal decomposition characteristics of 2,4 dinitroanilino acetic acid, 2,4,6 trinitro anilino acetic acid and their methyl and ethyl esters have been investigated by DTA. It is concluded from a study of the kinetic parameters of their decomposition, intramolecular hydrogen bonds existing in these compounds and mass spectral fragmentation characteristics of ethyl esters that these compounds decompose by the loss of OH through a cyclic intermediate formed by the intramolecular hydrogen bonding between the amino hydrogen atom and ortho nitro group.
