Nickel (II) acetylacetonate is a chemical compound of nickel from the group of acetylacetonates .
Extraction and presentation
Nickel (II) acetylacetonate dihydrate can be obtained by reacting nickel (II) salts with acetylacetonate in the presence of a weak base such as sodium acetate . The dihydrate can easily be converted to anhydrate in a vacuum at 50 ° C.
properties
Nickel (II) acetylacetonate is a light green solid that is soluble in water, ethanol and toluene. In solution, the compound is present as a trimer.
use
Nickel (II) acetylacetonate is used as a catalyst and UV stabilizer. It is also used as a starting material for the production of nickel bis (cyclooctadiene) catalysts and is also used in the deposition of nickel (II) oxide thin films by sol-gel techniques on conductive glass substrates. It is also used in organic synthesis for the production of organometals.
