Reaction of ethene with steam conditions

WebJul 18, 2024 · Ethanol can also be made by reacting ethene with steam. This process is called hydration. Mixture of ethene and steam is passed over a phosphoric acid catalyst at a temperature of 300°C and 60-70 atmospheres of pressure. The ethene required for this reaction is obtained from crude oil. High temp. ethene+steam-----> ethanol. High pressure WebThe reaction of ethene with steam to form ethanol can be reversed. This allows ethanol to be converted into ethene. 34 related questions found.
