为了深入讨论腈类一氯化锌络台物[ZnCl_2(NCR)_n,式中n=1和2]的聚合机理,我们曾研究了乙腈、丙腈络合物的某些热力学性质,本文进一步研究了它们的热分解过程。一、实验方法和结果所用乙腈、丙腈一氯化锌络合物[ZnI_2(NCR)_2]的制备方法与前相同。 1、热分解温差曲线用手记式Курнаков差热仪。中性体为灼烧过的Al_2O_3,与样品比例为1.46:1。样品用1克左右。升温速度1—6°/分,其中3°/分较好。升温速度偏差≤±0.3°/份。实验在N_2气氛中进行。分解温差曲线能重复。图1—A和图1—C分别为ZnCl_2(NCCH_3)_2
In order to further discuss the polymerization mechanism of [ZnCl_2 (NCR) _n, where n = 1 and 2], we have studied some thermodynamic properties of acetonitrile and propionitrile complexes. In this paper, Studied their thermal decomposition process. First, the experimental methods and results The preparation of acetonitrile, propionitrile zinc chloride complex [ZnI_2 (NCR) _2] the same way as before. 1, thermal decomposition temperature curve with a hand-written Курнаков differential heat meter. Neutrals were calcined Al 2 O 3, with a sample ratio of 1.46: 1. The sample is about 1 gram. Heating rate 1-6 ° / min, of which 3 ° / min is better. Temperature deviation ≤ ± 0.3 ° / copies. The experiment was carried out in N 2 atmosphere. Decomposition temperature curve can be repeated. Figure 1-A and Figure 1-C are respectively ZnCl_2 (NCCH_3) _2
