(N/A) Production of methanol: Methanol is known as wood spirit,as it was formerly produced by the destructive distillation of wood. Currently,it is produced by the catalytic hydrogenation of carbon monoxide in the presence of $Cr_2O_3-ZnO$ catalyst at high temperature $(573-673 \ K)$ and high pressure $(200-300 \ atm)$.
$CO + 2H_2 \longrightarrow CH_3OH$
$(b)$ Physical properties: Methanol is a colorless liquid and is highly poisonous in nature. Its boiling point is $337 \ K$.
$(c)$ Physiological effects: Consumption of even small quantities of methanol can cause blindness,and large quantities can lead to death.
$(d)$ Uses: It is used as a solvent in paints and varnishes,and primarily in the manufacture of formaldehyde $(HCHO)$.
