Cobaltic acetylacetonate Usage And Synthesis
PreparationCobaltic 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 Propertiessolid
UsesCobalt(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.
UsesCatalyst 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 ExplosibilityNotclassified
Purification MethodsRecrystallise it from *C6H6/pet ether and dry it in a vacuum. [Charles & Pawlikowski J Phys Chem 62 440 1938, Beilstein 1 H 783.]
