Phenol is industrially manufactured by the **cumene process** instead of Dow's process because the cumene process
Aoperates at higher temperature
Bgives a higher-purity phenol
Cuses cheaper benzene
Dco-produces valuable acetone
Answer & Solution
Correct answer: D. co-produces valuable acetone
Dow's process is harsh (623 K, 300 atm) and gives only phenol. Cumene runs near atmospheric conditions AND co-produces acetone, which has its own market — improving overall economics dramatically.
