The Macaffe's process is used for the chlorination of alumina (Al₂O₃) to produce anhydrous aluminum chloride (AlCl₃). This reaction involves heating alumina with carbon and chlorine gas.

The correct reaction is:

$${\mathrm{Al}}_2{\mathrm{O}}_3(s)+3\mathrm{C}(s)+3{\mathrm{Cl}}_2(g)⟶2{\mathrm{AlCl}}_3(s)+3\mathrm{CO}(g)$$
