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.

In carbohydrate chemistry carbohydrate acetalisation is an organic reaction and a very effective means of providing a protecting group. The example below depicts the acetalisation reaction of D-ribose 1. With acetone or 2,2-dimethoxypropane as the acetalisation reagent the reaction is under thermodynamic reaction control and results in the ...
Acetone and acetic anhydride ((CH 3 C(O)) 2 O) upon the addition of boron trifluoride (BF 3) catalyst: [11] (CH 3 C(O)) 2 O + CH 3 C(O)CH 3 → CH 3 C(O)CH 2 C(O)CH 3 A second synthesis involves the base-catalyzed condensation (e.g., by sodium ethoxide CH 3 CH 2 O − Na + ) of acetone and ethyl acetate , followed by acidification of the sodium ...
It also paved the way for later name reactions, like the Jocic–Reeve reaction and the Corey–Link reaction. The Jocic–Reeve and Corey–Link reactions are almost always featured together with the Bargellini reaction in a MCR. The reaction itself has been modified several times to increase efficiency or produce a modified product.
Acetone is prepared by air-oxidation of cumene. For specialized or small scale organic synthetic applications, ketones are often prepared by oxidation of secondary alcohols: R 2 CH(OH) + "O" → R 2 C=O + H 2 O. Typical strong oxidants (source of "O" in the above reaction) include potassium permanganate or a Cr(VI) compound.
Acetoacetic esters are used for the acetoacetylation reaction, which is widely used in the production of arylide yellows and diarylide dyes. [3] Although the esters can be used in this reaction, diketene also reacts with alcohols and amines to the corresponding acetoacetic acid derivatives in a process called acetoacetylation .
Phase equilibrium diagram for 1-butanol–ethanol–water ternary mixture. For this reason, in order to have a comparable productivity and profitability with respect to the petrochemical processes, cost and energy effective solutions for the product purification sections are required to provide a significant product recovery at the desired purity.
The reaction product is a vicinal diol. The reaction is named after pinacol (also known as 2,3-dimethyl-2,3-butanediol or tetramethylethylene glycol), which is the product of this reaction when done with acetone as reagent. The reaction is usually a homocoupling but intramolecular cross-coupling reactions are also possible.
