F. The Dehydration of Butan-2-ol - Chemistry LibreTexts
WebJul 7, 2024 · 2-Butanol, or sec-butanol, is an organic compound with formula CH3CH(OH)CH2CH3. This secondary alcoholis a flammable, colorless liquid that is soluble in three parts water and completely miscible with organic solvents. When Butan-2-OL is heated with h2so4 the major product is? WebThe dehydration reaction of alcohols to generate alkene proceeds by heating the alcohols in the presence of a strong acid, such as sulfuric or phosphoric acid, at high temperatures. The required range of reaction temperature decreases with increasing substitution of the hydroxy-containing carbon: 1° alcohols: 170° - 180°C. WebJan 23, 2024 · The facts Propan-2-ol can be dehydrated to give propene by heating it with an excess of concentrated sulphuric acid at about 170°C. Concentrated phosphoric (V) acid, H 3 PO 4, can be used instead. The acids aren't written into the equation because they serve as catalysts. preparing celery sticks
