It begins with the initial conversion of acetone to acetone cyanohydrin via reaction with hydrogen cyanide (HCN): In a subsequent step, the nitrile is hydrolyzed to the unsaturated amide, which is esterified: The third major use of acetone (about 20%)[22] is synthesizing bisphenol A. Bisphenol A is a component of many polymers such as polycarbonates, polyurethanes, and epoxy resins. [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. Acetone is the simplest ketone, also known as dimethyl ketone or propanone. While every effort has been made to follow citation style rules, there may be some discrepancies. The partial vapour pressure of a component in a mixture is equal to the vapour pressure of the pure component at that temperature multiplied by its mole fraction in the mixture. At any temperature a liquid partly vaporizes into the space above it until the pressure exerted by the vapour reaches a characteristic value called the vapour pressure of the liquid at that temperature. Boiling points of common materials. Static discharge may also ignite acetone vapors, though acetone has a very high ignition initiation energy point and therefore accidental ignition is rare.

Notify me of followup comments via e-mail, Written by : Dr. Mariam Bozhilova Forest Research Institute, BAS. At higher altitudes the pressure that is felt on the volume of water is low and corresponding to the pressure, the temperature required to boil the water is also reduced and hence the boiling point of water is lower at high altitudes. Cite Acetone has a polar CO double bond, which results in dipole-dipole forces. When we talk about the boiling pointwe refer to the temperature that a liquid must reach to become a gas, in other words to go from a liquid state to a gaseous state, chemically and physically the boiling pointis said to be the temperature required in the vapor pressure of a substance to be equal to the pressure that the environment exerts on it. [92] In making its decision EPA conducted an extensive review of the available toxicity data on acetone, which was continued through the 2000s. The only limiting factor with TLC analysis is the necessity for the components to be soluble in whatever solution is used to carry the components up the analysis plate. Water is an inorganic compound with a chemical formula H2O. Its chemical formula is C3H6O. [76], Acetone has been shown to have anticonvulsant effects in animal models of epilepsy, in the absence of toxicity, when administered in millimolar concentrations.
