| | Cobaltic acetylacetonate Usage And Synthesis |
| Preparation | Cobaltic acetylacetonate is dark green crystal, soluble in most organic solvents, but insoluble in water. It can be prepared from basic cobalt carbonate (II) and acetylacetone by adding hydrogen peroxide solution under stirring. | | Chemical Properties | solid | | Uses | Cobalt(III) 2,4-pentanedionate is used as a polymerization catalyst, vulcanizing agent, pigment in resins and glass. It is also used for the preparation of monoporphyrinates. Further, it is used in kinetic studies of iron-sulfur proteins. In addition to this, it reacts with trimethylaluminum to prepare Me(Sub>3Al/Co(acac)3. | | Uses | Catalyst for olefins, diens, polyesters, combustion, solid propellants; polymerization; vulcanizing; coloring for synthetic resins; deposition of
metal and/or oxide as memory storage for computers; intermediate for synthesis; glass tinting. | | Flammability and Explosibility | Not classified | | Purification Methods | Recrystallise it from *C6H6/pet ether and dry it in a vacuum.
