Zinc acetylacetonate is a chemical compound from the group of acetylacetonates .
Extraction and presentation
Zinc acetylacetonate can be obtained by reacting zinc sulfate with acetylacetone and sodium hydroxide .
properties
Zinc acetylacetonate is a crystalline solid that is sparingly soluble in water. The monomer which has the monoclinic space group C 2 / c (space group no. 15) can be crystallized by sublimation . The trimer with the monoclinic space group C 2 (space group no. 5) was also obtained by sublimation . Crystal structures of the monohydrate and dihydrate are also known.
use
Zinc acetylacetonate is used as a hydrate for the production of magnetic (Zn, Fe) Fe 2 O 4 films, zinc oxide and as a catalyst in organic chemistry.
