| 英文摘要 | Two new oxovanadium complexes with poly(pyrazolyl)borate and carboxylic acid as ligands, VO [PhCH2CH(NH2)COO][HB(pz)3] (1) and VO(3,5-Me(2)pz)[HB(3,5-Me(2)pz)(3)](CH3COO) (2), were synthesized successfully. The two complexes were characterized by IR, elemental analyses, thermal analyses, and single crystal X-ray diffraction. The study of non-isothermal decomposition kinetics for complex 1 showed that the possible reaction mechanisms of the two steps were nucleation and growth with n=1/4, and chemical reaction, respectively; the kinetic equations may be expressed as d alpha/dT=(A/beta)e(-E/RT)(1/4)(1-alpha)[-ln(1-alpha)](-3) and d alpha/dT=(A/beta)e(-E/RT)(1-alpha)(2), respectively, the apparent activation energies of the steps are 223.52 and 331.94 kJ.mol(-1), respectively, the pre-exponentials ln(A/s(-1)) are 49.67 as well as 57.50. The study of non-isothermal decomposition kinetics for complex 2 showed: the possible reaction mechanisms of the two steps were chemical reaction, and nucleation and growth with n=1/2, respectively, the kinetic equations may be expressed as d alpha/dT=(A/beta)e(E/RT)(l-alpha)(2), and d alpha/dT=(A/beta)e(-E/RT)(1/2)(1-alpha)[-ln(l-alpha)](-1), respectively, the apparent activation energies of the steps were 300.56 and 444.72 kJ.mol(-1), respectively, the pre-exponentials ln(A/s(-1)) were 75.53 as well as 92.50. |
