Copper chromium as hydrogenation catalysts in organic synthesis have been 70 years of history. At present,copper chromium has been used for aldehyde, ketone, fatty acid or ester reduction of alcohols, is also used forthe hydrogenation of nitrobenzene to aniline, carbon monoxide hydrogenation, automobile exhaust purification,can also be used for selective hydrogenation to improve the stability of oil oil, has been used in industrial production. It has a good catalytic effect on combustion of copper chromium propellant, can not only improve the burning rate of the propellant, but also has low pressure index.
