WebIodoform (HCI 3) is an analogue of chloroform (HCCl 3) but with rather different properties. It is a pale yellow, somewhat oily solid at ordinary temperatures. It has long been used … 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. It is synthesized in the haloform reaction by the reaction of iodine and sodium hydroxide with any …
