Editing Acetophenone (section)

==Production==
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 reaction|rearrangement]] of the  intermediate:
:{{chem2 | C6H5C(CH3)2O2H -> C6H5C(O)CH3 + CH3OH }}
The cumene process is conducted on such a large scale that even the small amount of acetophenone by-product can be recovered in commercially useful quantities.<ref name=Ullmann/> 

Acetophenone is also generated from [[ethylbenzene hydroperoxide]]. Ethylbenzene hydroperoxide is primarily converted to [[1-phenylethanol]] (α-methylbenzyl alcohol) in the process with a small amount of by-product acetophenone. Acetophenone is recovered or hydrogenated to 1-phenylethanol which is then dehydrated to produce styrene.<ref name=Ullmann/>
