(From the Latin. Acetum - vinegar) - the first of a homologous series of aliphatic ketones. The formula (CH3) 2CO.
A colorless volatile liquid with a characteristic odor. Unlimited mixed with water and polar organic solvents, also in limited proportions mixed with nonpolar solvents.
Acetone is a valuable industrial solvent and small toxicity due to it has been widely used in the manufacture of paints, explosives, drugs.
He is the feedstock to many chemical syntheses. In laboratory practice, it is used as a polar aprotic solvent for the preparation of compounds with cooling with dry ice and ammonia, acetone is very useful for chemical washing dishes.
Use acetone, acetic anhydride synthesis, atsetontsyanhydrina, difenilpropana and other organic products.
It is used to dissolve natural resins, oils, cellulose diacetate, polystyrene, epoxy resins, vinyl chloride copolymers, poshakrilatov, hlorkauchuk.
Included in the mixed solvent: P-4 (R-4A), P-5 (R-5A), P-646, P-647, P-648, and others.
It is used for degreasing surfaces.
Acetone can also be used for quick-breeding paints (varnishes, paints, enamels, soils, fillers) and to dissolve natural resins, cellulose diacetate, polystyrene, epoxy resins, vinyl chloride copolymers, polyacrylate, etc. hlorkauchuk
Acetone is a product of metabolism in living organisms, including humans. He is one of the components of the so-called acetone bodies that are in the blood of a healthy person contains very little, but in pathological conditions (prolonged fasting, heavy physical exertion, severe diabetes) their concentration can significantly increase and reach 20 mmol / l (ketonemiya) .
In Ukraine, acetone, according to the Cabinet of Ministers of 5 December 2012 g. N 1129 "On approval of the list of narcotic drugs, psychotropic substances and precursors", is the precursor for which the controls are set. Also in the same control measures to be substances containing no less than 50% of acetone
