Butanone, also known as methyl ethyl ketone, has a sweet acetone-like smell. It is often described as having a sharp, pungent odor similar to nail polish remover.
Substances that are polar or have similar polarity to 2-butanone are likely to dissolve in it. This includes compounds like some salts, sugars, and certain organic molecules. Non-polar substances like oils and fats are not likely to dissolve in 2-butanone.
Butanone can be reduced to butan-1-ol using reducing agents like sodium borohydride or lithium aluminum hydride. The carbonyl group of butanone is reduced to a primary alcohol group by adding the reducing agent in a suitable solvent under controlled conditions. Purification of the alcohol product is typically done through distillation or extraction methods.
To distinguish between butanal and butanone: Perform a Brady's test: butanone will give a positive result by forming a yellow or orange precipitate with 2,4-dinitrophenylhydrazine whereas butanal will not. Perform a chromic acid test: butanal will form a green color whereas butanone will not react. Conduct a Tollens' test: butanone will not react with Tollens' reagent whereas butanal will form a silver mirror precipitate indicative of an aldehyde.
One common method to separate butanone from ethanol is to utilize the difference in boiling points between the two compounds. Butanone boils at a higher temperature than ethanol, so a process like fractional distillation can be used to separate the two substances based on their different boiling points.
The product of the oxidation of 2-butanone is 2-butanoyl peroxide. This is formed through the insertion of an oxygen atom between the carbonyl carbon and the alpha carbon of the ketone.

The chemical formula for butanone is C4H8O. It is a ketone compound with a four-carbon chain and a ketone functional group.
2-Butanone, also known as methyl ethyl ketone (MEK), is a colorless liquid with a sweet, but sharp odor. 2-Butanone is manufactured in large amounts for use in paints, glues, and other finishes because it rapidly evaporates and will dissolve many substances. It will quickly evaporate into the air. 2-Butanone is often found dissolved in water or as a gas in the air. 2-Butanone is also a natural product made by some trees and is found in some fruits and vegetables. The exhausts of cars and trucks release 2-butanone into the air. 2-Butanone is usually found in the air, water, and soil of landfills and hazardous waste sites.
To synthesize 1-hydroxy-3-butanone from ethyl acetoacetate, first convert ethyl acetoacetate to ethyl acetoacetate phenylhydrazone using phenylhydrazine. Then, cyclize the phenylhydrazone to form the desired 1-hydroxy-3-butanone product. Hydrolyze the phenylhydrazone under acidic conditions to obtain the final product, 11-diphenyl-1-hydroxy-3-butanone.
because 2-butanone is a mixture so ethanol and water do not but mixtures do.

Butanone contains a ketone functional group. This functional group consists of a carbonyl group attached to two alkyl groups.

Conduct a Tollens' test: butanone will not react with Tollens' reagent whereas butanal will form a silver mirror precipitate indicative of an aldehyde.
The iodoform test is used to detect the presence of a methyl ketone. When 2-butanone is treated with iodine and sodium hydroxide, a yellow precipitate of iodoform (CHI3) forms if 2-butanone is present. This test confirms the presence of a methyl ketone functional group in the compound.
