| 英文摘要 | the heat capacities of 3-(2,2-dichloroethenyl)-2,2-dimethylcyclopropanecarboxylic acid(a racemic mixture, molar ratio of cis-/trans-structure is 35/65) in a temperature range from 78 to 389 k were measured with a precise automatic adiabatic calorimeter. the sample was prepared with a purity of 98. 75% (molar fraction). a solid-liquid fusion phase transition was observed in the experimental temperature range. the melting point, t-m., enthalpy and entropy of fusion, (delta)f(us)h(m), delta s-fus(m), of the acid were determined to be (331.48 +/- 0.03) k, (16.321 +/- 0.031) kj/mol, and (49.24 +/- 0.19) j/(k center dot mol), respectively. the thermodynamic functions of the sample, h-t - h-298.15, st - s-298.15 and g(t) - g(298.15), were reported at a temperature intervals of 5 k. the thermal decomposition of the sample was studied using thermogravimetric(tg) analytic technique, the thermal decomposition starts at ca. 418 k and ends at ca. 544 k, the maximum decomposition rate was obtained at 510 k. the order of reaction, preexponential factor and activation energy are n 0.23, a = 7.3 x 10(7) min e = 70.64 kj/mol, respectively. |
