In methanol, a new complex was synthesized by the reaction of salicylaldehyde-1H-benzotriazole-1-acetylhydrazone (C15H13N5O2, abbreviated as SBTH) with lanthanum perchlorate. The new complexes were characterized by elemental analysis, chemical analysis and thermal analysis Its composition was determined as La (C; .11; .N.O.) (C; O The structure of the complex was estimated by means of conductivity measurement, FTIR, 1HNMR and TG-DTG, etc. The complex was dissolved and calcined at different concentrations (b) by microcalorimeter, and the complex was obtained by computer simulation (ΔsolH = -135.62-11633b + 3761.5b1 / 2) of the standard molar dissolution curve (△ solHm? = - 135.62kJ · mol-1) and the enthalpy of solution The empirical formula of relative apparent molar enthalpy (φLi), relative partial molar (Li) and complex dilute enthalpy (△ dilH1,2): φLi = -11633b +3761.5b1 / 2; Li = -23266b + 5642.2b1 / 2 and △ dilH1,2 = -11633 (b2 1/2-b1 1/2) +3761.5 (b2-b1) The thermal decomposition process of the complex was also studied. The Kissinger formula was used to calculate the main decomposition phase of the complex Of apparent activation energy (Es = 470.24KJ · mol-1).
