Industrial Synthesis

Acetone is an organic compound with the formula (CH3)2CO. Acetone is the simplest Ketone which is Propan-2-one. Acetone can be produced using different methods which are the Cumene Process, From Alkane nitriles, the hydrolysis of Gem-Dihalides, the Oxidation of Isopropyl Alcohol, the Ozonolysis of Alkenes and the Fermentation Process.
Cumene Process – The process was invented by Heinrich Hock in 1944 and also independently by R. Udris and P.Sergeyev in 1942. This process uses to relatively cheap base starting materials benzene and propylene and this creates two much more valuable materials Phenol and Acetone. This is the most popular method to produce Acetone. It is produced by compressing Benzene and Propylene at 30 standard atmospheres at 250 degrees Celsius in the presence of a catalytic lewis acid. This is most likely to be Phosphoric acid as it is usually favoured over aluminium halides. The cumene is then oxidized in air which removes the tertiary benzylic hydrogen which forms a cumene radical. This radical molecule then bonds with an oxygen molecule forming cumene peroxide radical which then forms cumene hydroperoxide by taking out a benzylic hydrogen from another cumene molecule. The latter cumene converts into cumene radical and feeds back into
