[23], Like most ketones, acetone exhibits the ketoenol tautomerism in which the nominal keto structure (CH3)2C=O of acetone itself is in equilibrium with the enol isomer (CH3)C(OH)=(CH2) (prop-1-en-2-ol). Azeotropes exist in solution at a boiling point specific for that component. 0 4 5 o C / m m H g. This organic compound is found in the environment, in some plants, in trees, in the gases emitted by volcanoes, it is produced in forest fires, and in the degradation of fats in organisms. The boiling point of a substance depends on a lot of factors such as humidity, atmospheric pressure and even altitude. At temperatures greater than acetone's flash point of 20C (4F), air mixtures of between 2.5% and 12.8% acetone, by volume, may explode or cause a flash fire. [65], Acetone is used to precipitate proteins. Acetone: After a prolonged starvation or diet the stock of carbohydrates in the body is depleted, the fat is decomposed, which results in the production of acetone. . Acetones boiling point is 56C, and its melting point is -95C. [22], Acetone is a good solvent for many plastics and some synthetic fibers. At industrial levels, it has been possible to produce much more acetonethan what occurs naturally and spontaneously in the environment. For example, ethanol, with a molecular weight (MW) of 46, has a boiling point of 78 C (173 F), whereas propane (MW 44) has a boiling point of 42 C (44 F). The boiling point of any substance is defined based on the temperature it requires to change its phase. At higher altitudes the temperature of the boiling point is lower. Fluoride Levy, "Acetone" in Ullmann's Encyclopedia of Industrial Chemistry, Wiley-VCH, Weinheim, 2005. [43], In the presence of suitable catalysts, two acetone molecules also combine to form the compound diacetone alcohol (CH3)C=O(CH2)C(OH)(CH3)2, which on dehydration gives mesityl oxide (CH3)C=O(CH)=C(CH3)2.
