| Application: | Potassium iodide can be used as a reducing agent for the reduction of graphene oxide in the presence of hydrochloric acid. It is also used as a dopant in the preparation of solid polymer electrolytes for energy devices. |
| Features and Benefits: | • Increased efficiency – Eliminates time and effort of loosening hardened powders • Safety – Eliminates tools of force used to break up clumps • Ecology – Reduces waste as it does not stick to the packaging • Economy – Faster preparation and solvation increase productivity and reduce costs • Assured Quality – Excellent, expert-tested quality with no anti-caking agents • Flexible volumes – Available from research amounts to scale-up quantities |
| General description: | Potassium iodide is an inorganic sodium salt. It is used as a source of iodide in organic synthesis. In the presence of oxidizing agents, it iodinates aromatic hydrocarbons and organothallium compounds. It is also used as a reagent for the cleavage of some ethers in the presence of acid. |
