Web3 de abr. de 2024 · Orthophosphoric acid or H 3 P O 4 when heated to a temperature of 250 ∘ C yields pyrophosphoric acid and water as products of its reaction. This following … WebIntroduction The 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
WebIn this process, ethanol is heated with an excess of concentrated sulfuric acid at a temperature of 170°C. The gases produced are passed through a sodium hydroxide solution to remove the carbon dioxide and sulfur dioxide produced from side reactions. The ethene is collected over water. The concentrated sulfuric acid is a catalyst.
