A variety of organic reactions employ acetone as a polar, aprotic solvent, e.g. the Jones oxidation. Because acetone is cheap, volatile, and dissolves or decomposes with most laboratory chemicals, an acetone rinse is the standard technique to remove solid residues from laboratory glassware before a final wash.

With acetone, ketene reacts to give isopropenyl acetate. [1] A variety of hydroxylic compounds can add as nucleophiles, forming either enol or ester products. As examples, a water molecule easily adds to ketene to give 1,1-dihydroxyethene and acetic anhydride is produced by the reaction of acetic acid with ketene.
Water-reactive substances [1] are those that spontaneously undergo a chemical reaction with water, often noted as generating flammable gas. [2] Some are highly reducing in nature. [ 3 ] Notable examples include alkali metals , lithium through caesium , and alkaline earth metals , magnesium through barium .
DMP is used as a water scavenger in water-sensitive reactions. Upon acid-catalyzed reaction, DMP reacts quantitatively with water to form acetone and methanol. [2] This property can be used to accurately determine the amount of water in a sample, alternatively to the Karl Fischer method. [3] DMP is specifically used to prepare acetonides: [4] [5]
Cooling baths are generally one of two types: (a) a cold fluid (particularly liquid nitrogen, water, or even air) — but most commonly the term refers to (b) a mixture of 3 components: (1) a cooling agent (such as dry ice or ice); (2) a liquid "carrier" (such as liquid water, ethylene glycol, acetone, etc.), which transfers heat between the ...
In aqueous media, acrylonitrile also reacts with formaldehyde to give crude N,N′-methylenebisacrylamide, which can be purified by recrystallization with acetone/water. [ 5 ] Reactions and uses
Acetone oxime (acetoxime) is the organic compound with the formula (CH 3) 2 CNOH. It is the simplest example of a ketoxime . It is a white crystalline solid that is soluble in water, ethanol, ether, chloroform, and ligroin.
In organic chemistry, a cyanohydrin reaction is an organic reaction in which an aldehyde (−CH=O) or ketone (>C=O) reacts with a cyanide anion (N≡C −) or a nitrile (−C≡N) to form a cyanohydrin (>C(OH)C≡N). For example:
