Ethene and steam mechanism
WebInstitute of Physics WebEthanol can be synthesised by the hydration of ethene. Ethene is a by-product of the cracking of hydrocarbons and is a valuable feedstock for making many chemicals. The hydration reaction is very important industrially for the production of alcohols and it occurs using the following conditions: Temperature of around 330ºC. Pressure of 60 ...
