说明

General description

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.

Application

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.
