Application

Chromium(III) chloride can be used in the formation of a catalytic system for the conversion of glucose into 5-hydroxymethylfurfural (HMF). It can also be used in the preparation of ionic liquid mixtures using choline chloride and water with improved ion mobility and conductivity.
The vapor-phase co-reductions with other metal halides by hydrogen results in finely divided intermetallics with applications as structural materials or compounds with useful thermoelectric, magnetic, and oxidation-resistance properties.2
