Chemical, physical and thermal properties of acetone, also called 2-propanone, dimethyl ketone and pyroacetic acid. Phase diagram included. Acetone (2-propanone), CH3-CO-CH3, is a clear colorless liquid with a characteristic fruity and sweetish odor. It is flammable and vapors are heavier than air. Acetone is toxic in high doses.

The cumene process is used to convert benzene and propene in the presence of oxygen to phenol and acetone via the following reaction. This reaction is carried out in with excess benzene and excess oxygen to ensure that no side reactions occur. A 1.13 ratio of benzene to propene is fed to a reactor in the presence of 28.5% excess air (N2 and O2).
· The process has the potential to change the acetone/MEK ratio within reasonable limits to meet varying market demands. Although the cost of making the phenol is higher than the conventional cumene route due to higher raw material costs, the large byproduct credit received for the MEK more than makes up for these costs, says Nexant.

The cumene process method is quite expensive, since it requires the raw materials and extra separation equip-ment to separate acetone from many different materials (Moore & Parker, 2007; Coulson et al., 1999b). Therefore, this study focuses on the more economic method of decomposition of isopropyl alcohol over the cumene process method.

The Q-MAX™ process flow scheme is shown in fig 2.1 above. The alkylation reactor is divided into four catalytic beds present in a single reactor shell.
In the production of Acetone different methods are presented, of which three are outstanding: Cumene process, oxidation process of polypropylene and the process of dehydrogenation of Isopropyl alcohol. The Cumene process is the most common worldwide, but as a byproduct, is benzene (carcinogen) lowering the purity of Acetone

· The production of acetone from only cumene would require a balancing of the market with the phenol product from this process. Therefore, there is a need of alternative routes for acetone production other than the cumene process. Dehydrogenation of IPA over a metal, metal oxide or salt catalysts is the second route for the manufacture of acetone ...

Acetone is produced via several alternative processes, one of which is the Acetone Process via Dehydrogenation of 2-Propanol (IPA). This endothermic gas-phase reaction converts IPA to acetone and hydrogen. The process has two distillation columns and an absorber column in which a water stream is used to recover acetone.
