Commercially anhydrous chromium(III) chloride may be prepared bychlorination of chromium metal directly, or indirectly by chlorination ofchromium(III) oxide in the presence of carbon at 650--800 °C, with carbon monoxide as a side-product:[3]

Cr2O3 + 3 C + 3 Cl2 → 2 CrCl3 + 3 CO

It may also be prepared by treating the hexahydrate with thionyl chloride:[4]

CrCl3·6H2O + 6 SOCl2 → CrCl3 + 6 SO2 + 12 HCl
