碘化钯（II）在苯乙炔氧化羰基化反应中用作催化剂，该反应在pH和反应热两者中均表现出振荡行为。在试图提取负责该反应的振荡性质的反应网络中，将系统分成较小的部分并对其进行研究。本文着重于了解负责碘化钯（II）在此振荡反应的初始反应的反应网络。研究的物种包括甲醇、碘化钯（II）、碘化钾和一氧化碳。几个化学反应被认为是和应用在一个模拟研究。该研究揭示了所使用的标准HPLC级甲醇中所含的痕量水所起的重要作用。
Palladium(II) iodide is used as a catalyst in the phenylacetylene oxidative carbonylation reaction that has demonstrated oscillatory behaviour in both pH and heat of reaction. In an attempt to extract the reaction network responsible for the oscillatory nature of this reaction, the system was divided into smaller parts and they were studied. This paper focuses on understanding the reaction network responsible for the initial reactions of palladium(II) iodide within this oscillatory reaction. The species researched include methanol, palladium(II) iodide, potassium iodide, and carbon monoxide. Several chemical reactions were considered and applied in a modelling study. The study revealed the significant role played by traces of water contained in the standard HPLC grade methanol used.
