Acetone (2-propanone or dimethyl ketone) is an organic compound with the formula (CH 3) 2 CO. [22] It is the simplest and smallest ketone (>C=O).It is a colorless, highly volatile, and flammable liquid with a characteristic pungent odour, very reminiscent of the smell of pear drops.

Historically called white gas, it is a liquid petroleum fuel (100% light hydrotreated distillate). [1] White gas was originally simply additive-free gasoline. This formulation is now rarely found. Coleman fuel, and other white gases, contain additives for inhibiting rust, ease of lighting, and fast burning.
For the process to be economical, both phenol and the acetone by-product must be in demand. [23] [24] In 2010, worldwide demand for acetone was approximately 6.7 million tonnes, 83 percent of which was satisfied with acetone produced by the cumene process. A route analogous to the cumene process begins with cyclohexylbenzene.
Dimers also occur in the liquid phase in dilute solutions with non-hydrogen-bonding solvents, and to a certain extent in pure acetic acid, [23] but are disrupted by hydrogen-bonding solvents. The dissociation enthalpy of the dimer is estimated at 65.0–66.0 kJ/mol, and the dissociation entropy at 154–157 J mol −1 K −1 . [ 24 ]
Both flasks are submerged in a dry ice/acetone cooling bath (−78 °C) the temperature of which is being monitored by a thermocouple (the wire on the left). A cooling bath or ice bath , in laboratory chemistry practice, is a liquid mixture which is used to maintain low temperatures, typically between 13 °C and −196 °C.
