一般描述

碘化钾（KI）是一种化合物，可作为亲核位移反应中的碘离子源。在醛类化合物的电化学氧化过程中，它起介质的作用。在酸环境下，它可以裂解一些醚。KI 在氧化剂环境下可将芳香化合物和有机铊化合物碘化。此外，它可以与磺酰氯反应形成对称的硫磺酸 S-酯。

应用

碘化钾可用作：
  • 碘源，以叔丁基过氧化氢（TBHP）为氧化剂，从炔和酚合成 1-碘炔和碘酚的。
  • 催化剂，以磺酰肼为磺酰前体，水为溶剂，通过活化烯烃芳基磺酰化合成磺化氧吲哚。
  • 氧化降解抑制剂，以减少单乙醇胺（MEA）的氧化降解。

A simple color spot test for determining the presence of residual tetrabutylammonium (TBA) in various 18F-radiopharmaceuticals is described. The test can be performed in less than five minutes. Iodoplatinate-saturated TLC plates are initially spotted with the 18F-radiopharmaceutical to be tested

The effects of potassium iodide, colchicine and dapsone on the in vitro generation of polymorphonuclear leukocyte (PMN)-derived oxygen intermediates were investigated. These three drugs have beneficial effects on those conditions in which PMNs play an important pathogenetic role. Three oxygen

A novel method for the determination of iodide by size exclusion chromatography was established. The method was simple and highly sensitive with good precision. Iodide was converted to iodine, then sequestered with starch, and separated from the matrix using a
