Acetone (2-propanone or dimethyl ketone) is an organic compound with the formula (CH 3) 2 CO. [22] It is the simplest and smallest ketone (R−C(=O)−R').It is a colorless, highly volatile, and flammable liquid with a characteristic pungent odour, very reminiscent of the smell of pear drops.
In plants, terpenes and ... another by-product of conifer tree resin, is widely used as an ingredient in a variety of ... acetone and acetylene are condensed to give ...
The use of side products such as hydrogen and carbon dioxide, solid wastes and discharged microorganisms and carry out less expensive process wastewater treatments. In the second half of the 20th century, these technologies allowed an increase in the final product concentration in the broth from 15 to 30 g/L, an increase in the final ...
Acetone is a chemical used to remove nail polish from your nails or as a household cleaner. It also occurs naturally in your body, facilitating ketosis.
Acetone was used in the important wartime task of casting cordite. The alcohols were used to produce vehicle fuels and synthetic rubber . Unlike yeast , which can digest only some sugars into alcohol and carbon dioxide , C. acetobutylicum and other Clostridia can digest whey , sugar, starch , cellulose and perhaps certain types of lignin ...
Most of the worldwide production of phenol and acetone is now based on this method. In 2022, nearly 10.8 million tonnes of phenol was produced by the cumene process. [4] In order for this process to be economical, there must also be demand for the acetone by-product as well as the phenol. [5]
Isophorone, derived from acetone, is an unsaturated, asymmetrical ketone that is the precursor to other polymers. Muscone , 3-methylpentadecanone, is an animal pheromone . Another cyclic ketone is cyclobutanone , having the formula (CH 2 ) 3 CO .
Acetophenone is formed as a byproduct of the cumene process, the industrial route for the synthesis of phenol and acetone.In the Hock rearrangement of isopropylbenzene hydroperoxide, migration of a methyl group rather than the phenyl group gives acetophenone and methanol as a result of an alternate rearrangement of the intermediate:
