Iodoform (also known as triiodomethane) is the organoiodine compound with the chemical formula C H I 3. It is a pale yellow, crystalline, volatile substance, with a penetrating and distinctive odor (in older chemistry texts, the smell is sometimes referred to as that of hospitals, where the compound is still commonly used) and, analogous to ...
In 1822, Serullas added potassium metal to a solution of iodine in ethanol and water to form potassium formate and iodoform, called in the language of that time hydroiodide of carbon, [1] and used as an antiseptic. He is buried in the Père Lachaise Cemetery (10th division). [2] Tomb of Georges Simon Serullas at Père-Lachaise Cemetery
She died on 21 December after intense suffering involving daily medication with iodoform, a foul-smelling and painful corrosive treatment typically used at the time and administered by Bloch. Because of the poor economic situation of the Hitler family, Bloch charged reduced prices, sometimes taking no fee at all.
In chemistry, the haloform reaction (also referred to as the Lieben haloform reaction) is a chemical reaction in which a haloform (CHX 3, where X is a halogen) is produced by the exhaustive halogenation of an acetyl group (R−C(=O)CH 3, where R can be either a hydrogen atom, an alkyl or an aryl group), in the presence of a base.
Iodomethane may also be prepared by treating iodoform with potassium hydroxide and dimethyl sulfate under 95% ethanol. [7] In the Tennessee Eastman acetic anhydride process iodomethane is formed as an intermediate product by a catalytic reaction between methyl acetate and lithium iodide.
Most of the haloforms — specifically, chloroform (CHCl 3), bromoform (CHBr 3), and iodoform (CHI 3) — are easy to prepare through the haloform reaction, although this method does not lend itself to bulk syntheses. (Fluoroform (CHF 3) cannot be prepared in this manner.)
Prior to the introduction of this chromium-based protocol, olefination reactions generally gave Z alkenes or mixtures of isomers. [1] Similar olefination reactions had been performed using a variety of reagents such as zinc and lead chloride; [5] however, these olefination reactions often lead to the formation of diols—the McMurry reaction—rather than the methylenation or alkylidenation of ...
Medical iodophor (Chinese povidone-iodine solution) An iodophor is a preparation containing iodine complexed with a solubilizing agent, such as a surfactant or water-soluble polymers such as povidone (forming povidone-iodine), [1] [2] The result is a water-soluble material that releases free iodine when in solution.
