In 1833, French chemists Antoine Bussy and Michel Chevreul decided to name acetone by adding the suffix -one to the stem of the corresponding acid (viz, acetic acid) just as a similarly prepared product of what was then confused with margaric acid was named margarone. In 1832, French chemist Jean-Baptiste Dumas and German chemist Justus von Liebig determined the empirical formula for acetone. History Īcetone was first produced by Andreas Libavius in 1606 by distillation of lead(II) acetate. The prefix refers to acetone's relation to vinegar ( acetum in Latin, also the source of the words "acid" and "acetic"), rather than its chemical structure. Unlike many compounds with the acet- prefix having a 2-carbon chain, acetone has a 3-carbon chain which has caused confusion since there cannot be a ketone with 2 carbons. Names derived from mesit include mesitylene and mesityl oxide which were first synthesised from acetone. Prior to the "acetone" name given by Antoine Bussy, it was named "mesit" (from the Greek μεσίτης, meaning mediator) by Carl Reichenbach who also claimed that methyl alcohol consisted of mesit and ethyl alcohol. Those names include spirit of Saturn, which was given when it was thought to be a compound of lead, and later pyro-acetic spirit and pyro-acetic ester. Name įrom the 17th century and before modern developments in organic chemistry nomenclature, acetone was given many different names. Ketogenic diets that increase ketone bodies (acetone, β-hydroxybutyric acid and acetoacetic acid) in the blood are used to counter epileptic attacks in children who suffer from refractory epilepsy. People with diabetic ketoacidosis produce it in larger amounts. It is normally present in blood and urine. Īcetone is produced and disposed of in the human body through normal metabolic processes. It has volatile organic compound (VOC)-exempt status in the United States. It serves as a solvent in household products such as nail polish remover and paint thinner. It is a common building block in organic chemistry. About 6.7 million tonnes were produced worldwide in 2010, mainly for use as a solvent and for production of methyl methacrylate and bisphenol A, which are precursors to widely used plastics. It is a colorless, highly volatile and flammable liquid with a characteristic pungent odor.Īcetone is miscible with water and serves as an important organic solvent in industry, home, and laboratory. It is the simplest and smallest ketone ( >C=O).
