Witryna28 sie 2024 · The iodoform test is one of the important qualitative analyses to know the presence of acetyl group in the substrate, which is commonly taught in high school or introductory chemistry. When a substrate possessing an acetyl group is reacted with iodine under alkaline conditions, iodoform is observed as yellow precipitates [ 1 ], 2 ]. The synthesis of iodoform was first described by Georges-Simon Serullas in 1822, by reactions of iodine vapour with steam over red-hot coals, and also by reaction of potassium with ethanolic iodine in the presence of water; and at much the same time independently by John Thomas Cooper.
