Acetone
Acetone, also known as propanone or dimethyl ketone, is a ketone with the formula (CH3)2CO. It’s the simplest and tiniest in the ketone family. It’s a colourless, extremely volatile, combustible liquid with a distinctive pungent odour. Acetone is miscible with water and is used as an organic solvent in business, at home, and in the laboratory. In 2010, around 6.7 million tonnes were manufactured globally, mostly for use as a solvent and the synthesis of methyl methacrylate (and thus PMMA) and bisphenol A. In organic chemistry, it is a common building block. Acetone is commonly used in home products such as nail polish remover and paint thinner. In the United States, it is free from volatile organic compound (VOC) regulations. Acetone is created and eliminated by regular metabolic processes in the human body. It’s usually seen in the blood and urine. It is produced in greater quantities in diabetic ketoacidosis patients. It has a modest possibility for causing reproductive difficulties, according to reproductive toxicity tests. Ketogenic diets, which raise blood levels of ketone bodies (acetone, -hydroxybutyric acid, and acetoacetic acid), are used to prevent epileptic seizures in infants and children with refractory epilepsy.

Acetone: Properties
- Acetone has been widely examined and is thought to have just a minor toxicity in regular use. If basic safeguards are taken, there is no compelling evidence of long-term health impacts.When consumed and/or inhaled, it is usually thought to have low acute and chronic toxicity. [69] Acetone is not currently considered a carcinogen, mutagenic chemical, or a source of long-term neurotoxicity.
- Acetone produces acetone peroxide as a byproduct when it is oxidised, which is a very unstable, main high explosive chemical. It can arise by accident, for example, when waste hydrogen peroxide is injected into acetone-containing waste solvent. Despite its straightforward chemical production, it is rarely employed due to its volatility.
- Acetone, like most ketones, exhibits the keto–enol tautomerism, in which the enol isomer (CH3)C(OH)=(CH2) is in equilibrium with the nominal keto structure (CH3)2C=O (prop-1-en-2-ol). Only 2.4×10−7% of the molecules in acetone vapour at room temperature are in the enol state. However, in some chemical processes, the enol form is crucial.
- Acetone is known to generate two types of polymers and (perhaps cyclic) oligomers. Units could be acetone molecules linked by ether bridges –O– produced from the opening of the double bond to form a polyketal-like (PKA) chain [–O–C(CH3)2–]n in one kind.
- Two acetone molecules react in the presence of adequate catalysts to generate diacetone alcohol (CH3)C=O(CH2)C(OH)(CH3)2, which dehydrates to mesityl oxide (CH3)C=O(CH)=C(CH3)2. This product can be combined with another acetone molecule, resulting in phorone and other chemicals with the loss of another molecule of water.
Acetone Formula and Reaction in Chemistry
METHOD 1
Propylene can be used to make acetone either directly or indirectly. The cumene process produces about 83 percent of acetone; as a result, acetone manufacturing is linked to phenol production. Cumene is produced by alkylating benzene with propylene, which is then oxidised by air to create phenol and acetone:
Other methods include directly oxidising propylene (Wacker-Hoechst process) or hydrating propylene to produce 2-propanol, which is then oxidised (dehydrogenated) to acetone.
METHOD 2
Acetone was previously made by dry distilling acetates, such as calcium acetate in ketonic decarboxylation.
| Ca(CH3COO)2 → CaO(s) + CO2(g) + (CH3)2CO (v) |
Following that, in the manufacturing of Cordite, acetone was created utilising acetone-butanol-ethanol fermentation using Clostridium acetobutylicum bacteria, which was developed by Chaim Weizmann (later the first president of Israel) to aid the British war effort. When newer technologies with higher yields were discovered, the acetone-butanol-ethanol fermentation was eventually abandoned.

Acetone: FAQs
Ques. What is acetone be used for?
Ans. Acetone is a liquid solvent that has the ability to dissolve and break down other compounds. Acetone is found in nail polish removers, paint removers, and varnish removers, among other things. Acetone is also used to make polymers, lacquers, and fabrics.
Ques. How is acetone harmful to humans?
Ans. Acetone is a liquid solvent that has the ability to dissolve and break down other compounds. Acetone is found in nail polish removers, paint removers, and varnish removers, among other things. Acetone is also used to make polymers, lacquers, and fabrics.
Ques. What does acetone do to the skin?
Ans. Acetone dehydrates the nail plate, cuticles, and surrounding skin, causing nails to become dry and brittle, as well as cuticles to become dry, flaky, red, and irritable.
Ques. Is acetone the same as nail polish remover?
Ans. Acetone is a colourless, volatile, flammable liquid that is water miscible. Nail polish remover, on the other hand, is an organic solvent that may contain pigment, fragrances, oils, and solvents.
Ques. Is acetone toxic when dry?
Ans. The vapour affects the eyes as well. Ingestion is not dangerous. If consumed in high doses, it can have the same effects as inhalation. Long-Term (Chronic) Exposure Effects: Following skin contact, it can produce dry, red, cracked skin (dermatitis).
