N—乙酰乙酰基酰胺及其金属络合物的合成和成冰性能曾作过报导,前文主要是讨论正构脂肪烃及氟代芳香烃酰胺类化合物。本文为了进一步探讨含有不同取代基及其铜络合物与成冰性能的关系,我们合成了含有氯、碘、硝基的N—乙酰乙酰基芳香烃酰胺及其相应的铜络合物,通过对其阈温的检测,以便从化合物结构的角度来了解其成冰性能,为探索新的人工成冰核物质提供些依据。本文中Cu(Ⅱ)络合物的合成和成冰阈温均未见报导。阈温测试发现配位体阈温值均较碘化银(-4℃)低,而它们相应的Cu(Ⅱ)络合物阈温值又都较碘化银稍高。值得注意的是前文也有类似结果。
The synthesis and icing properties of N-acetoacetylamides and their metal complexes have been reported. The preceding paragraphs mainly deal with n-aliphatic and fluorinated aromatic amides. In order to further explore the relationship between different substituents and their copper complexes with ice-forming properties, we synthesized N-acetoacetyl aromatic amide containing chlorine, iodine and nitro and their corresponding copper complexes by The detection of its threshold temperature, in order to understand the structure of the ice from the perspective of its properties, to explore new artificial ice nucleation provide some evidence. In this paper, the synthesis of Cu (Ⅱ) complexes and ice-forming threshold temperature were not reported. Threshold temperature showed that the threshold temperature of the ligands was lower than that of silver iodide (-4 ℃), while the corresponding threshold temperature of Cu (Ⅱ) complexes was slightly higher than that of silver iodide. It is worth noting that the previous article has similar results.
