一般描述
Potassium iodide (KI) is an inorganic potassium salt. It is used as an iodide ion source for nucleophilic displacement reactions and acts as a mediator during the electrochemical oxidations of aldehydes. In presence of an acid, KI cleaves some ethers. KI reacts with sulfonyl chlorides to produce symmetrical thiosulfonic S-esters. In the presence of oxidizing agents, KI iodinates aromatic compounds and organothallium compounds.
应用
Potassium iodide is used:
- As a solid base catalyst loaded with alumina for transesterification of soybean oil with methanol.
- As a iodide source in the solvothermal synthesis of BiOI (bismuth oxyiodide) microspheres using ethylene glycol solvent.
- In the synthesis of RGO (reduced graphene oxide) from GO (graphite oxide) in presence of HCl–KI mixture.

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
