Ethylene oxide is produced by oxidation of ethylene in presence of AgO catalyst at __________________?
Correct answer: B. 5 atm & 275°C
- A. 1 atm & 100°C
- B. 5 atm & 275°C
- C. 100 atm & 500°C
- D. 50 atm & 1000°C
Explanation
Ethylene is directly oxidised over a silver catalyst at moderate pressure and about 250 to 300°C to form ethylene oxide. Among the choices, 5 atm and 275°C is the appropriate operating condition.
