The Commercial Solvents Corporation was established at the end of World War I; earning distinction as the pioneer producer of acetone and butanol by fermentation processes developed and patented by Dr. Chaim Weizmann.
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 (>C=O).It is a colorless, highly volatile, and flammable liquid with a characteristic pungent odour, very reminiscent of the smell of pear drops.
Acetone is prepared by air-oxidation of cumene. For specialized or small scale organic synthetic applications, ketones are often prepared by oxidation of secondary alcohols: R 2 CH(OH) + "O" → R 2 C=O + H 2 O. Typical strong oxidants (source of "O" in the above reaction) include potassium permanganate or a Cr(VI) compound.
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. Uses and Benefits of Acetone
First stage of Hock process: alkylation of benzene with propylene. Second stage of Hock process: autoxidation of cumene. The cumene process (cumene-phenol process, Hock process) is an industrial process for synthesizing phenol and acetone from benzene and propylene.
Acetylacetone is prepared industrially by the thermal rearrangement of isopropenyl acetate. [10] Laboratory routes to acetylacetone also begin with acetone. Acetone and acetic anhydride ((CH 3 C(O)) 2 O) upon the addition of boron trifluoride (BF 3) catalyst: [11] (CH 3 C(O)) 2 O + CH 3 C(O)CH 3 → CH 3 C(O)CH 2 C(O)CH 3
Bromoacetone is available commercially, sometimes stabilized with magnesium oxide. It was first described in the 19th century, attributed to N. Sokolowsky. [3] Acetone and bromine form bromoacetone. Bromoacetone is prepared by combining bromine and acetone, [4] with catalytic acid. As with all ketones, acetone enolizes in
