Production

Acetone is produced primarily in the cumene process. Previously, acetone was produced by the dry distillation of acetates, for example calcium acetate. During World War I a new process of producing acetone through bacterial fermentation was developed by Chaim Weizmann, later the first president of Israel, in order to help the British war effort. This Acetone Butanol Ethanol process was abandoned due to the small yield of Acetone Butanol compared to the organic waste. Cumene process is an industrial process of producing phenol (C6H5-OH) and acetone (CH3-CO-CH3) from benzene (C6H6) and propene (C3H6). ...

Automotive fuel additive

Some automotive enthusiasts add acetone at around 1 part in 500 to their fuel, following claims of dramatic improvement in fuel economy and engine life.[3] This practice is controversial as there are counterclaims that acetone has no measurable effect or may in fact reduce engine life by adversely affecting fuel system parts.[4][5][6] Debates on this subject and claims of Big Oil cover-up intensified when the practice was addressed on the popular American TV show MythBusters in 2006, and shown to have negative effect in the televised fuel economy test.[7]. MythBusters is an American popular science television program on the Discovery Channel starring American special effects experts Adam Savage and Jamie Hyneman, who use basic elements of the scientific method to test the validity of various rumors, urban legends and news stories in popular culture. ...


Some cars that are prone to incomplete fuel burning because they are badly tuned or getting old (clogged carburator, air filter or fuel line, etc.) may experience improvement of fuel consumption because acetone will act as a parts cleaner and dessicant by adsorbing water present in fuel. To expect any fuel consumption benefits, the acetone or any high octane fuel additive (ethanol, etc.) would have to be put in a higher compression ratio engine. Since only the compression ratio can make any energy efficiency difference in a carefully tuned engine. So only a volume reduction of the combustion room when the piston is in the max compression position would make a more efficient thermodynamic cycle and better fuel consumption. A tuned compression ratio engine would then requires only high octane fuel to avoid self fuel ignition by pressure (engine knocking).[citation needed]


Other uses

Acetone is also used as a drying agent, due to the readiness with which it mixes with water, and its volatility. A desiccant is a substance that adsorbs moisture from the air. ...


It can be used as an artistic agent; when rubbed on the back of a laser print or photocopy placed face-down on another surface and burnished firmly, the toner of the image is allowed to transfer to the destination surface.


Safety

Acetone peroxide

Main article: acetone peroxide

When oxidized, acetone forms acetone peroxide as a by-product, which is a highly unstable compound. It may be formed accidentally, e.g. when waste hydrogen peroxide is poured into a carboy containing waste acetone solvent. Acetone peroxide is more than ten times as friction and shock sensitive as nitroglycerin. Due to its unstability, it is rarely used, despite its easy chemical synthesis. Acetone peroxide Ball-and-stick model of the acetone peroxide trimer (TATP) Acetone peroxide (triacetone triperoxide, peroxyacetone, TATP, TCAP) is an organic peroxide and a primary high explosive. ...

Toxicology

Acetone is an irritant and inhalation may lead to hepatotoxic effects (causing liver damage). The vapors should be avoided. In no circumstance should it be consumed directly or indirectly. Always use goggles when handling acetone; it can cause permanent eye damage (corneal clouding). Hepatotoxicity (from hepatic toxicity) is chemical-driven liver damage. ...


Small amounts of acetone are metabolically produced in the body, mainly from fat. In humans, fasting significantly increases its endogenous production (see ketosis). Acetone can be elevated in diabetes. Contamination of water, food (e.g. milk), or the air (acetone is volatile) can lead to chronic exposure to acetone. A number of acute poisoning cases have been described. Relatively speaking, acetone is not a very toxic compound; it can, however, damage the mucosa of the mouth and can irritate and damage skin. Accidental intake of large amounts of acetone may lead to unconsciousness and death. Ketosis (IPA pronunciation: ) is a stage in metabolism occurring when the liver converts fat into fatty acids and ketone bodies which can be used by the body for energy. ... This article is about the disease that features high blood sugar. ... The mucous membranes (or mucosa) are linings of ectodermic origin, covered in epithelium, that line various body cavities and internal organs. ... For other uses, see Mouth (disambiguation). ...


The effects of long-term exposure to acetone are known mostly from animal studies. Kidney, liver, and nerve damage, increased birth defects, and lowered reproduction ability of males (only) occurred in animals exposed long-term. It is not known if these same effects would be exhibited in humans. Pregnant women should avoid contact with acetone and acetone fumes in order to avoid the possibility of birth defects, including brain damage. The kidneys are the organs that filter wastes (such as urea) from the blood and excrete them, along with water, as urine. ... The liver is the largest internal organ in the human body, and is an organ present in vertebrates and some other animals. ... For other uses, see Nerve (disambiguation). ... A congenital disorder is a medical condition or defect that is present at or before birth (for example, congenital heart disease). ...


Interestingly, acetone has been shown to have anticonvulsant effects in animal models of epilepsy, in the absence of toxicity, when administered in millimolar concentrations.[8] It has been hypothesized that the high fat low carbohydrate ketogenic diet used clinically to control drug-resistant epilepsy in children works by elevating acetone in the brain.[8] The anticonvulsants, sometimes also called antiepileptics, belong to a diverse group of pharmaceuticals used in prevention of the occurrence of epileptic seizures. ... The ketogenic diet is a very high fat diet that relies on inducing a state of ketosis. ...
