Which compound is formed on catalytic hydrogenation of carbon monoxide at high $p$ and high $\mathrm{T}$ in presence of $\mathrm{ZnO}-\mathrm{Cr}_2 \mathrm{O}_3$ catalyst?
$\mathrm{CH}_3 \mathrm{OH}$
$\mathrm{CH}_3 \mathrm{COOH}$
$\mathrm{CH}_3 \mathrm{CH}_2 \mathrm{OH}$
Solution
$\mathrm{CO}+\mathrm{H}_2 \xrightarrow[\text { High pressure }(673 \mathrm{~K}, 300 \mathrm{~atm}) \mathrm{ZnO}-\mathrm{Cr}_2 \mathrm{O}_3]{\stackrel{\text { High temperature }}{\longrightarrow}} \underset{\text { Methanol }}{\mathrm{CH}_3 \mathrm{OH}}$
Methanol is industrially prepared when mixture of carbon monoxide and hydrogen is subjected to high temperature and pressure in presence of $\mathrm{ZnO}-\mathrm{Cr}_2 \mathrm{O}_3$ as catalyst.
