Description of Chromium(III) nitrat

Chromium(III) nitrate describes several inorganic compounds consisting of chromium, nitrate and varying amounts of water. Most common is the dark violet hydrated solid, but an anhydrous green form is also known. Chromium(III) nitrate compounds are of a limited importance commercially, finding some applications in the dyeing industry. It is common in academic laboratories for the synthesis of chromium coordination complexes.

What is Chromium(III) nitrat?

  • With the progress of science and technology and the development of society, chemical products have invariably permeated our daily lives, in medicine, food, cosmetics, electronics, industry, and other areas, becoming an essential part of our lives. One such product is Chromium(III) nitrat which has developed particularly rapidly in recent years. Do you know about Chromium(III) nitrat?
  • The official answer: Chromium nitrate is an inorganic compound with the chemical formula Cr(NO3)3. There are anhydrous substances and various hydrates. The anhydrous substance is brown amorphous, and recrystallizes in an aqueous solution to give a green crystalline salt, which becomes trihydrate when it absorbs moisture in the air, in addition to several tetra-, Penta-, Hexa-, hepta-, and dodeca-hemihydrates [1]. The melting point of heptahydrate is 100°C [2]. The melting point of dodecahemihydrate is 104-105°C. Industrial chromium nitrate is usually 9 aqueous, red-purple orthogonal monoclinic crystals, relative density 1.80 [1], soluble in water, acid, alkali, ethanol, acetone, its aqueous solution is a good dielectric, toxic, 60 ℃ dissolved in its own crystalline water, 125.5 ℃ boiling, and decomposition, hydrated chromium nitrate in air weathering will lose part of the crystalline water, and easy to deliquescence [3]. It is used in glass manufacturing, printing and dyeing, and chromium catalysts. It is produced by the reaction of chromium trioxide with nitric acid by reduction with sucrose.

What’s the application of Chromium(III) nitrat?

Used as a water-based adhesive with a cross-linking agent, can improve the water-resistance of polyvinyl acetate emulsion, 100 parts of white emulsion using 10 parts of Cr(NO3)3-9H2O aqueous solution.
Used in glass manufacturing, printing and dyeing, and preparation of chromium-containing catalysts, etc.
