摘要: The (S)-alpha-cyano-3-phenoxybenzyl (1R)-cis-3-(2,2-dibromovinyl)-2,2-dimethylcyclo- propane carboxylate, or named deltamethrin (C22H19Br2NO3), is one of the high effective fenpropathrin pesticides. The compound was synthesized and characterized with NMR. The purity of sample used for calorimetric study was determined to be 0.9926 % by HPLC. The molar heat capacities of the compound were measured with an automatic adiabatic calorimeter in the temperature range of 80 ~ 400 K. The experimental molar heat capacities of the sample were fitted to polynomials with the least square fittings. The deviation of the experimental data from the smoothed values in the whole region is within ± 0.2 %. A solid-liquid phase transition was observed in the experimental temperature range. The melting point, (Tm), enthalpy and entropy of fusion,(Δfus Hm) and (ΔfusSm) were determined to be 372.15±0.02K,26.73±0.02 kJ• mol -1,71.81±0.06 J• K-1• mol -1, respectively. The thermodynamic functions of the compound, [HT – H298.15], [ST – S298.15] and [GT -G298.15] were derived with a temperature interval of 5 K in the temperature range of 298.15~ 400 K. The thermal decomposition of the compound was studied by thermogravimetric analysis (TG) in the temperature range of 470~ 680 K. The TG analysis indicated that the thermal decomposition of the compound starts at 510 K and ends at 575 K; the maximum decomposition rate was observed at 556 K. The order (n), pre-exponential factor (A) and activation energy (E) of the decomposition reaction were determined to be 1.78, 1.15•109 min-1 and 603.8 kJ•mol-1, respectively.
