During the industrial synthesis of phenol via the Dow's process, chlorobenzene is reacted with 10% NaOH. What are the required temperature and pressure?
Q1. During the industrial synthesis of phenol via the Dow's process, chlorobenzene is reacted with 10% NaOH. What are the required temperature and pressure?
Answer: 360C and 150 atm
Explanation: Dow's process requires 360C and 150 atm to convert chlorobenzene to phenol. Higher pressures like 300 atm are typical for Haber's process, not Dow's.
