Reaction of ethene with steam catalyst
WebIn this process ethene and steam (water in the gaseous phase) are passed at 300°C and a pressure approximately 60 times above atmospheric pressure over a phosphoric acid catalyst to produce ethanol. This reaction is reversible with only 5% of the ethene converting to ethanol with each pass over the catalyst in the reactor. WebSteam cracking uses a higher temperature of over 800°C and no catalyst; ... Alkenes can take part in reactions that alkanes cannot. For example, ethene molecules can react …
