(CH 3)2CO    **
 * ACETONE

Acetone is also known as dimethyl ketone, 2-propanone, and beta-ketopropane. Acetone is the simplest form of a ketone ketone: a compound with the structure RC(=O)R', where R and R' can be a variety of atoms and groups of atoms. It features a carbonyl group (C=O) bonded to two other carbon atoms.

 **PHYSICAL PROPERTIES** > >  Acetone is manufactured mainly by the cumene peroxidation or <span style="font-family: 'Lucida Sans Unicode','Lucida Grande',sans-serif;"> isopropyl alcohol dehydrogenation processes. The cumene peroxidation process produces trace quantities of benzene as a by-product.
 * high evaporation rate
 * low viscosity
 * miscibility with water and several organic (benzene & ethanol)

(CH3)2CH-OH → (CH3)2CO + H2 dehydrogenation process of isopropyl alcohol

Acetone occurs naturally in plants, trees, volcanic gases, forest fires, and as a product of the breakdown of body fat. It is present in vehicle exhaust, tobacco smoke, and landfill sites.

 * A large percentage (97%) of the acetone released during its manufacture or use goes into the air.
 * In air, about one-half of the total amount breaks down from sunlight or other chemicals every 22 days.
 * It moves from the atmosphere into the water and soil by rain and snow. It also moves quickly from soil and water back to air.
 * Acetone doesn't bind to soil or build up in animals.
 * It's broken down by microorganisms in soil and water.
 * It can move into groundwater from spills or landfills.
 * Acetone is broken down in water and soil, but the time required for this to happen varies.

Industrial processes contribute more acetone to the environment than natural processes.

Dearest Sue,

The first thing I noticed was that your wiki is very well organized and clearly explains all the required aspects of the post. Another aspect of the wiki that I am impressed with is the amount of fine art work that is present throughout the wiki. In my opinion, something that could be changed is going from bullet notes to full sentences in order to give a more full effect. Another part of the wiki that could use is some clarification on units of measurement like the angles of the acetone molecule or a little more clarification on what a ketone is. Other than that, the wiki provides exceptional information on acetone and goes above and beyond the call of Williams.

Sincerely, Matthew James "Peach" Beach
