Acetone structure uses and facts :
Acetone structure uses and facts are listed here briefly by the way you can clear your doubts about it all.
Facts of acetone :
Here are some facts about acetone given below :
1.Acetone is a, highly flammable and volatile liquid, used as a and synthesis intermediate.
2.With the formula C 3 H 6 O, it gives off a characteristic odor, both acrid and.
3. Its double bond carbon-oxygen and the presence ofto in the alpha position (α) give it a high reactivity to many products.
4.Stable under usual conditions, acetone can thus react strongly with powerfulas chromic , hot nitric acid, , hydrogen peroxide, somehalogenated (trichloromethane, tribromomethane …) or in the presence of a strong base (for example or potassium ).
5. Not corrosive to, it attacks certain .
6.Acetone may cause severeirritation , nausea, dizziness or when high concentrations of vapors (above 10,000 ).

Uses of acetone:
Acetone is one of the most widely used organic solvents, which dissolves gums, resins,derivatives , greases, oils and . It is used in many formulations:
- paint, , lacquer;
- paint stripper and thinner;
- glue and adhesives;
- ink, dyes and their thinners;
- transport and storage of acetylene in compressed cylinders.
In the chemical industry, acetone is involved in many processes:
- manufacture of pharmaceutical and cosmetic products (eg , methamphetamine);
- extraction of fats, oils and waxes;
- purification of and (precipitating agent);
- paraffin purification;
- cleaning and drying glassware in the laboratory;
- cleaning and drying of electronic parts;
- cooling medium in mixture ;
- manufacture of Plexiglas ( );
- manufacture of ;
- manufacture of explosive powders;
- manufacture and spinning of cellulose acetate fibers (eg, paper glue, photographic film bases, synthetic fibers, rayon, artificial silk, viscose);
- manufacture of resin objects reinforced with glass fibers.
Acetone and environment:
Various activities can release acetone into the:
- exhaust gas ;
- combustion of and ;
- degradation of waste in landfills;
- paper industry;
- cigarette smoke.
Acetone can also emanate from particle board, carpets or certain coatings. It also comes from natural sources during forest fires or.
Acetone in biology:
Acetone is naturally produced and excreted in the body during metabolic processes, especially when food is insufficient (fasting,) or in ( ).
The body then degradesin the form of ketone bodies. The excess acetone is manifested by a characteristic odor of the breath and a high concentration in the urine.
If acetone builds up too much, it causes ketoacidosis, a toxic acidification of the blood that can lead to.
