Vinyl chloride (CH2 = CH.Cl) is produced by the thermal pyrolysis of ethylene dichloride at a pressure & temperature of __________________?
Correct answer: A. 4 kgf/cm2 & 500°C
- A. 4 kgf/cm2 & 500°C
- B. 10 kgf/cm2 & 1000°C
- C. 40 kg/cm2 & 200°C
- D. 100 kgf/cm2 & 500°C
Explanation
Ethylene dichloride is cracked at about 500°C to form vinyl chloride and hydrogen chloride; the listed low pressure is the closest standard operating condition among the choices. The other options pair the reaction with clearly unsuitable temperatures or pressures.
