"Symmetrical Trinitrotoluene is stable in the presence of moisture, but the nonsymmetrical trinitrotoluenes permit replacement of a nitro group with the formation of a nitrated cresol and nitrous acid. Nitrated cresols form salts similar to the picrates. To avoid these nonsymmetrical trinitrotoluenes the Ordinance Department, U. S. A., requires that Grade I trinitrotoluene have a solidification point of at least 80.2⁰C.². Numerous methods for purifying the crude trinitrotoluene and others for separating the nitrotoluenes have been suggested"--Introduction, page 1.
