Question

Which of the following is the most suitable temperature and pressure conditions for production of methanol by catalytic hydrogenation?

(a) 300K, 100atm

(b) 400K, 250atm

(c) 500K, 275atm

(d) 600K, 300atm

I got this question during an interview.

My question comes from Commercially Important Alcohols in division Alcohols, Phenols and Ethers of Chemistry – Class 12

Answer 1

Correct option is (d) 600K, 300atm

For explanation I would say: Methanol is produced by catalytic hydrogenation of carbon monoxide at high pressure (200-300atm) and high temperature (573-673K) in the presence of ZnO-Cr2O3 catalyst.
