Ledeţi I, Alexa A, Bercean V, Vlase G, Vlase T, Şuta LM, Fuliaş A - Int J Mol Sci (2015)

Bottom Line: This paper reports on the synthesis and characterization of two Schiff bases bearing 1,2,4-triazolic moieties, namely 4H-4-(2-hydroxy-benzylidene-amino)-5-benzyl-3-mercapto-1,2,4-triazole and 4H-4-(4-nitro-benzylidene-amino)-5-benzyl-3-mercapto-1,2,4-triazole using thin layer chromatography, melting interval, elemental analysis, spectroscopy and thermal stability studies.

ijms-16-01711-f007: FR diagram, for SB2 derivative.

Mentions: For α = constant and using the five heating rates, the correlation ln (β·dα/dT) vs. (1/T) is linear. From the slopes of these straight lines which form the Friedman diagram (see Figure 6 and Figure 7), the values of the activation energy (Ea) for the two compounds are obtained (Table 1).
