Haloform Reaction Mechanism - Step by Step Explanation and ... - BYJUS

In chemistry, the haloform reaction is a chemical reaction in which a haloform (CHX3, where X is a halogen) is produced by the exhaustive halogenation of an acetyl group (R−C(=O)CH3, where R can be either a hydrogen atom, an alkyl or an aryl group), in the presence of a base. The reaction can be … See more In the first step, the halogen dis-proportionates in the presence of hydroxide to give the halide and hypohalite. If a secondary alcohol is present, it is oxidized to a ketone by the hypohalite: If a methyl ketone … See more Laboratory scale This reaction forms the basis of the iodoform test which was commonly used in history as a chemical test to determine the presence of a … See more Substrates are broadly limited to methyl ketones and secondary alcohols oxidizable to methyl ketones, such as isopropanol. The only primary alcohol and aldehyde to undergo this reaction are ethanol and acetaldehyde, respectively. 1,3-Diketones such as See more The haloform reaction is one of the oldest organic reactions known. In 1822, Georges-Simon Serullas added potassium metal to a solution of See more Web• Verminderung krebserregender Haloformbildung • • • • Abbau von vorhandenen Biofilmen • Geringe Betriebskosten (2 Cent / m3 ) • Sicher bei weit verzweigten Netzen • Wesentlich stärkere Desinfektionswirkung als Chlor.
