Acetophenone is formed as a byproduct of the cumene process, the industrial route for the synthesis of phenol and acetone.In the Hock rearrangement of isopropylbenzene hydroperoxide, migration of a methyl group rather than the phenyl group gives acetophenone and methanol as a result of an alternate rearrangement of the intermediate:
2-Aminoacetophenone, also known as β-ketophenethylamine, α-desmethylcathinone, or phenacylamine, is a substituted phenethylamine derivative. [1] [2] It is the phenethylamine homologue of cathinone (β-ketoamphetamine) and hence is a parent compound of a large number of stimulant and entactogen drugs.
Products of decomposition of cumene hydroperoxide are methylstyrene, acetophenone, and 2-phenylpropan-2-ol. [3] It is produced by treatment of cumene with oxygen, an autoxidation. At temperatures >100 °C, oxygen is passed through liquid cumene: [4] C 6 H 5 (CH 3) 2 CH + O 2 → C 6 H 5 (CH 3) 2 COOH. Dicumyl peroxide is a side product.
This latter cumene converts into cumene radical and feeds back into subsequent chain formations of cumene hydroperoxides. A pressure of 5 atm is used to ensure that the unstable peroxide is kept in liquid state. Cumene hydroperoxide undergoes a rearrangement reaction in an acidic medium (the Hock rearrangement) to give phenol and acetone. In ...
Phenacyl chloride, also commonly known as chloroacetophenone, is a substituted acetophenone.It is a useful building block in organic chemistry.Apart from that, it has been historically used as a riot control agent, where it is designated CN. [5]
2,2-Dimethoxy-2-phenylacetophenone is a photoinitiator, which is used to initialize radical polymerization e.g. in the preparation of acrylate polymers. [1] Under the influence of light the molecule will form radicals which initiate the radical polymerization. It can also be used as an initiator in the process of making an integrated circuit.
Tetramethyl acetyloctahydronaphthalenes (International Nomenclature for Cosmetic Ingredients name) (1-(1,2,3,4,5,6,7,8-ottaidro-2,3,8,8,-tetrametil-2-naftil)etan-1-one) is a synthetic ketone fragrance also known as OTNE (octahydrotetramethyl acetophenone) and by other commercial trade names such as: Iso E Super, Iso Gamma Super, Anthamber, Amber Fleur, Boisvelone, Iso Ambois, Amberlan, Iso ...
Piceol is used in the synthesis of several pharmaceutical drugs including octopamine, sotalol, bamethan, and dyclonine. [citation needed] Piceol can be used to make acetaminophen by condensation with hydroxylamine and subsequent Beckmann rearrangement in acid. [4] Anticonvulsants are also possible by Mannich reaction: [5]
