Question

How methanol is prepared industrially? Write the chemical equation.

Hint:

Remember the catalyst: Zinc oxide and Chromium oxide (ZnO–Cr₂O₃) are essential for this reaction to proceed efficiently at industrial scales.

Answer 1

Concept:
The industrial production of methanol (CH₃OH), also known as wood spirit, involves a high-pressure, high-temperature reaction between synthesis gas (CO + H₂).
Chemical Equation:
Carbon monoxide reacts with hydrogen gas in the presence of a catalyst:
CO + 2 H₂ → CH₃OH
Catalyst: ZnO–Cr₂O₃, Pressure: 200–300 atm, Temperature: 573–673 K
