Molecular Structure and Properties of a Novel Acylhydrazone (C14H14O6N4)·HCON(CH3)2·2H2O

N-(Propionic acid)] terephthalal acyl dihydrazone(H₄L) was synthesized and characterized by element analysis, IR, ¹H NMR and MS. The theoretical studies on H₄L were carried out at HF/6-31+G(d) and B3LYP/ 6-31+G(d) levels. The main decomposition stage of it was studied with IR track. The kinetic parametersthe apparent activation energy(E_a) and pre-exponential constant(A) of the first and second stages of decomposition reaction] were obtained by Kissinger and Ozawa’s methods. Furthermore, the antimicrobial activity of H₄L against wheat rust was investigated by spore sprout method.
