2. Ammonium iodide - Wikipedia

   en.wikipedia.org/wiki/Ammonium_iodide

   Ammonium iodide is the inorganic compound with the formula NH 4 I. A white solid. It is an ionic compound, although impure samples appear yellow. This salt consists of ammonium cation and an iodide anion. [1] It can be prepared by the action of hydroiodic acid on ammonia. It is easily soluble in water, from which it crystallizes in cubes.

3. Tetra-n-butylammonium iodide - Wikipedia

   en.wikipedia.org/wiki/Tetra-n-butylammonium_iodide

   The enthalpy of formation Δ f H 0 of tetra-n-butylammonium iodide is −499 kJ/mol, which is lower than that for the bromide or chloride (−540, −564 kJ/mol). [2] At lower temperatures with water tetra-n-butylammonium iodide forms a clathrate hydrate. [2] The tetra-n-butylammonium cation is large and hydrophobic.

4. Ammonium iodate - Wikipedia

   en.wikipedia.org/wiki/Ammonium_iodate

   Using its low solubility in water, it can also be precipitated from an iodate solution with an ammonium salt. 2 KIO 3 + (NH 4) 2 SO 4 → 2 NH 4 IO 3 + K 2 SO 4. Unlike other iodates, ammonium iodate can't be prepared by dissolving iodine in an ammonium hydroxide solution, instead the highly explosive nitrogen triiodide is formed. 3 I 2 + 5 NH ...

5. Portable water purification - Wikipedia

   en.wikipedia.org/wiki/Portable_water_purification

   Iodine used for water purification is commonly added to water as a solution, in crystallized form, or in tablets containing tetraglycine hydroperiodide that release 8 mg of iodine per tablet. The iodine kills many, but not all, of the most common pathogens present in natural fresh water sources.

6. Eschenmoser's salt - Wikipedia

   en.wikipedia.org/wiki/Eschenmoser's_salt

   It is the iodide salt of the dimethylaminomethylene cation [(CH 3) 2 NCH 2] +. The dimethylaminomethylene cation is a strong dimethylaminomethylating agent, used to prepare derivatives of the type RCH 2 N(CH 3) 2. [1] [2] Enolates, silyl enol ethers, and even more acidic ketones undergo efficient dimethylaminomethylation.

7. Cerium diiodide - Wikipedia

   en.wikipedia.org/wiki/Cerium_diiodide

   Cerium diiodide can be obtained from the reduction of cerium(III) iodide with metallic cerium under vacuum at 800 °C to 900 °C. [2] Ce + 2 CeI 3 → CeI 2. It can also be formed from the reaction of cerium and ammonium iodide in liquid ammonia at −78 °C. The reaction forms an ammonia complex of cerium diiodide, which decomposes to cerium ...
