Other names 1,2-Diacetylethane 'α','β'-Diacetylethane Acetonyl acetone Diacetonyl 2,5-Dioxohexane ... 2,5-Hexanedione (Acetonylacetone) is an aliphatic diketone.
It dissolves cellulose nitrate, vinyl polymers and copolymers, and natural and synthetic resins. It is recommended as a solvent because it is photochemically inactive; [5] however it has a very low safe threshold limit value. 2-Hexanone is absorbed through the lungs, orally and dermally and its metabolite, 2,5-hexanedione, is neurotoxic.

I 2 + 2 NaCH(C(O)CH 3) 2 → [CH(C(O)CH 3) 2] 2 + 2 NaI. Reminiscent of the case of acetylacetone, tetraacetylethane exists as the enol, as established by X-ray crystallography. The two C 3 O 2 H rings are twisted with a dihedral angle near 90°. [2] Many metal complexes have been prepared from the conjugate base of this ligand.
It forms the acetylacetonate anion C 5 H 7 O − 2 (commonly abbreviated acac −): C 5 H 8 O 2 ⇌ C 5 H 7 O − 2 + H + The structure of the acetylacetonate anion (acac −) In the acetylacetonate anion, both C-O bonds are equivalent. Both C-C central bonds are equivalent as well, with one hydrogen atom bonded to the central carbon atom (the ...
2,5-Hexanediol is an organic compound with the formula CH 3 CH(OH)CH 2 CH 2 CH(OH)CH 3. It is both a glycol and a secondary alcohol. [1] It is a colorless water-soluble viscous liquid. [2] [3] [4] The chemical properties are well understood and have been extensively reported and studied. [5]
These results suggest that other components found in petroleum benzine may have additive, synergistic or potentiative effects on the biological effects of n-hexane. [7] Namely, 1000 ppm n-hexane, 3000 ppm n-heptane, and 1000 ppm toluene were reported to have depressing effects on the body weight gain of rats.
5-Nonanone was expected to be metabolized to a γ-diketone (a diketone with the second oxygen three carbons away from the first, e.g. 2,5- or 3,6-diketones). Metabolic studies confirmed the in vivo ω-oxidation of 5-nonanone to 2,5-nonanedione and 2-hexanone. Subsequent oxidative and decarboxylative steps also produce 2,5-hexanedione.
The following is a list of chemicals published as a requirement of Safe Drinking Water and Toxic Enforcement Act of 1986, commonly known as California Proposition 65, that are "known to the state to cause cancer or reproductive toxicity" as of January 3, 2020. [1]
