| 摘 要： | 热重分析(TG)和微商热重法(DTG)广泛应用于各个研究领域,用非等温热重法测定固体化合物的热分解动力学参数已有报导.许多作者提出各种不同的数据处理方法.本文用的ρ-CH_3C_6H_4SR 型硫醚对钯的萃取具有选择性好、分配比高、气味较小、易溶于脂肪烃类溶剂、易于合成、是很有发展前途的一类萃取剂.我们合成五种ρ-CH_3C_6H_4SR(R:n-C_4H_9,n-C_6H_(13),n-C_8H_(17),n-C_(10)H_(21),n-C_(12)H_(25))型硫醚与钯(Ⅱ)的配合物,用TG-DTG 法研究它们的热分解过程,用微商法(Freeman-Carroll 方程)及积分法(Coats-Redfern 方程)获得了这些配合物的热分解动力学参数.

| Abstract: | Five kinds of thioether p-CH_3C_6H_4SR (R=n-C_4H_9, C_6H_(13), C_8H_(17), C_(10)H_(21), and C_(12)H_(25)) and their palladium complexes Pd(p-CH_3C_6H_4SR)_2Cl_2 were synthesized. The thermal decomposition of these complexes have been studied by using TG and DTG methods. It was found that the former two of the complexes firstly decompos into organic ligands and PdCl_2, then PdCl_2 to chlorine atoms and palladium; The latter three of complexes decompose into organic ligands chorine atoms and palladium almost simultaneously. Kinetic parameters such as activation energy E, frequency factor A and reaction order n were obtained using the Coats-Redfern and Freeman-Carroll methods. In addition, entropy of activation ΔS has also been calculated. |
