What is acetylacetone used for?
Acetylacetone is used in the production of anti-corrosion agents and its peroxide compounds for the radical initiator application for polymerisation. It is used as a chemical intermediate for drugs (such as sulphamethazine, nicarbazine, vitamin B6, and vitamin K) and pesticides sulfonylurea herbicides and pesticides.
What is acac ligand?
Metal acetylacetonates are coordination complexes derived from the acetylacetonate anion (CH. 3COCHCOCH − 3) and metal ions, usually transition metals. The bidentate ligand acetylacetonate is often abbreviated acac. Typically both oxygen atoms bind to the metal to form a six-membered chelate ring.
Is acac basic?
Acid–base properties Acetylacetone is a weak acid: C 5H 8O 2 ⇌ C 5H 7O−2 + H.
What is acac charge?
When deprotanated, each ligand carries a negative one charge and the 5 membered O-C-C-C-O ring is planar. The ligand is called acetonylacetonate and is abbreviated "acac".
