What are the conditions and catalyst required for the reaction:
Ethene + steam => ethanol.
Answers
Answer:
hey mate here is the answer
Explanation:
In this reaction, ethene (which comes from cracking crude oil fractions ) is heated with steam in the presence of a catalyst of phosphoric acid (to speed up the reaction):
This reaction typically uses a temperature of around 300°C and a pressure of around 60–70 atmospheres .
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
C2H4+H2O--------->C2H5OH
