Is acetylacetone a strong base?
Is acetylacetone a strong base?
Acid–base properties Acetylacetone is a weak acid: C 5H 😯 2 ⇌ C 5H 7O−2 + H. Very strong bases, such as organolithium compounds, will deprotonate acetylacetone twice.
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 the structure of acetylacetone?

Acetylacetone/Formula
What happens when Naoh is added to acetylacetone?
Acetylacetone (pentane-2,4-dione) reacts with sodium hydroxide to give water and the sodium salt of a carbanion. Acetylacetone (pentane-2,4-dione) reacts with sodium hydroxide to give water and the sodium salt of a carbanion.
Is acetylacetone corrosive to metals?
What is Acetyl Acetone? Pentanedione is a colorless liquid with a pleasant odor. This chemical is often used to clean metals, as a raw material in pharmaceuticals, and as an anti-corrosion agent. The presence of enol allows the compound to interact with metals such as cobalt, beryllium, aluminum, and chromium.
Why is acetylacetone a weak acid?
Acetonylacetone is CH3-CO-CH2-CH2-CO-CH3 (2,5-hexanedione). In acetonylacetone the middle hydrogens (on C3 and C4) are no more acidic than the hydrogens on a normal ketone. However, in acetylacetone, the middle hydrogens (on C3) are quite a bit more acidic than the hydrogens on a normal ketone.
Is acetylacetone a ketone?
Acetylacetone is a very clear, colorless to light yellow liquid ketone with a pleasant odor. Acetylacetone is also an important intermediate used in organic synthesis as a building block for heterocyclic compounds. and forms many complexes with transition metal ions where it acts as a metal chelating agent.
What type of molecule is acetylacetone?
Acetylacetone is an organic compound with the chemical formula CH3COCH2COCH3. It is a colorless liquid, classified as a 1,3-diketone. It exists in equilibrium with a tautomer CH3C(O)CH=(OH)CH3.
What is the density of acetylacetone?
980 kg/m³
Acetylacetone/Density
How do you make acetylacetone?
Acetylacetone has been prepared by the reaction of acetyl chloride with aluminum chloride, followed by hydrolysis;3 by the condensation of acetone with ethyl acetate in the presence of sodium,4 sodium amide,5,6 sodium ethoxide,5,7,8 and alkali or alkaline-earth hydrides;9 by the reaction of acetone and acetic anhydride …
Is acetylacetone flammable?
Flammable in the presence of a source of ignition when the temperature is above the flash point. Keep away from heat/sparks/open flame/hot surface. No smoking.
What is the normal boiling point of acetylacetone?
284°F (140°C)
Acetylacetone/Boiling point
Is acetylacetone a beta diketone?
Acetylacetone is a beta-diketone that is pentane in which the hydrogens at positions 2 and 4 are replaced by oxo groups. It is a conjugate acid of an acetylacetonate. Pentane-2,4-dione appears as a colorless or yellow colored liquid. Less dense than water. Vapors are heavier than air.
What is the chemical formula for acetylacetone?
Acetylacetone is an organic compound with the chemical formula CH 3COCH 2COCH 3.
What are the analogs of acetylacetonates?
A second synthesis involves the base-catalyzed condensation of acetone and ethyl acetate, followed by acidification: Because of the ease of these syntheses, many analogues of acetylacetonates are known. Some examples include C 3. Hexafluoroacetylacetonate is also widely used to generate volatile metal complexes.
Why is acetylacetone a bifunctional precursor to heterocycles?
Acetylacetone is a versatile bifunctional precursor to heterocycles because both keto groups undergo condensation. Hydrazine reacts to produce pyrazoles. Urea gives pyrimidines.
