WebThe hydration of ethene is a reversible reaction . The equilibrium position lies to the left, ... In 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. What are the uses of ethene? WebPolymerization (self addition) of ethene is an ionic or free-radical reaction. In this reaction, ethane add to itself in the presence of high temperature and pressure, using dibenzene peroxide (C 6 H 5 CO 2 ) as catalyst nCH 2 =CH2 2000atm [-CH 2 -CH 2 - CH 2 -CH 2 -]
During ethanol
WebThis is called hydration, and it needs a temperature of approximately 300°C and a catalyst.
