일반 설명
Copper chromite is a black powder and inorganic pigment thatadopts a spinel crystal structure. It can be made by the high-temperaturecalcination of copper(II) oxide and chromium(III) oxide or the thermaldecomposition of copper chromate, which evolves oxygen at higher temperaturesand decomposes to copper chromite.
애플리케이션
Copper chromite is primarily used as a catalyst for hydrogenation reactions because of its ability to hydrogenate functional groups in aliphatic and aromatic compounds selectively. Industrially, copper chromite is used to reduce furfural to furfuryl alcohol and butyraldehyde to 1-butanol,partially reduce conjugated dienes to monoenes, and selectively reduce carbonyl groups in vegetable oils. This CuCr catalyst is studied for a variety of catalytic applications including converting the hydrogenolysis of cellulose.It is also used as a catalyst for combustion to help control burn rate and as alight-absorbing pigment. Copper chromite/graphene oxide nanocomposite canbe used in energy storage applications.

A four-step catalytic process was developed to produce p-methylstyrene from methylfuran, a biomass-derived species. First, methylfuran was acylated over zeolite H-Beta with acetic anhydride. Second, the acetyl group was reduced to an ethyl group with hydrogen over copper chromite. Third
