Ethanol production by hydration of ethene
WebThe hydration of ethene is a reversible reaction . The equilibrium position lies to the left, so only about 5% of the ethene supplied is converted to ethanol. The overall yield of 95% is achieved by recirculating unreacted ethene through the reactor. What is used in the production of ethanol from ethene? WebMar 13, 2013 · Best Answer. Copy.
