One-pot synthesis of antiviral acyclovir and other nucleosides derivatives using doped natural phosphate as lewis acid catalyst. Natural phosphate doped with iodine or potassium iodide is an active catalyst for the one-pot synthesis of acyclonucleosides. To demonstrate the utility of... HB Lazrek,...
Calcium chloride is also used on the roads in cold climates to lower the freezing point of water. Most table salt that is purchased also contains potassium iodide, KI. The iodide ion is an important ion for human thyroid health. Rust is the result of iron reacting with oxygen to produce ...
(K),chemical elementof Group 1 (Ia) of theperiodic table, thealkali metalgroup, indispensable for bothplantand animal life. Potassium was the firstmetalto be isolated byelectrolysis, by the English chemistSir Humphry Davy, when he obtained the element (1807) by decomposing moltenpotassium ...
damage to skin and tissues.) For this reason, iodine is best weighed in a stoppered bottle; for the preparation of an aqueous solution, the bottle may contain a solution ofpotassiumiodide, which considerably decreases the vapor pressure of iodine; a brown complex (triiodide) is readily formed...
After cooling, 3 g of potassium iodide and 25 mL of sulfuric acid were added and titrated with a sodium thiosulfate solution until a light-yellow color was achieved. At the end, 1 mL of a starch solution was added. A similar procedure was employed for the blank sample, but 25 mL of ...
