Application

Anhydrous chromium chloride is an important precursor for the low temperature synthesis of anhydrous metal sulfides, nitrides, phosphides, etc. It is also an important precursor for the synthesis of chromium containing mixed metal complexes; example lithium chromium chloride (Li2CrCl4), which shows rapid lithium ion conduction.

Anhydrous chromium chloride finds applications as catalysts, chromizing ferrous metals, steel, etc. 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.

Chromium chloride powder is air and water sensitive. Beads have lower surface area and pour easily.

Efficient conversion of glucose to 5-hydroxymethyl furfural (5-HMF), a platform chemical for fuels and materials, was achieved using CrCl(2) or CrCl(3) as the catalysts with inexpensive co-catalysts and solvents including halide salts in dimethyl sulfoxide (DMSO) and several ionic liquids.

Production of 5-hydroxymethylfurfural (HMF) from glucose was studied in ionic liquids in the presence of hydroxyapatite supported chromium chloride (Cr-HAP) using oil-bath heating and microwave irradiation (MI). Compared with oil-bath heating, the MI way obviously increased HMF yield and reduced
