An industrial synthesis of paracetamol developed by Hoechst–Celanese involves the conversion of a methyl ketone to an acetanilide via a Beckmann rearrangement. [15] The thermal rearrangement that occurs in the synthesis of ketamine was claimed to be a Beckmann rearrangement according to: url.
Acetanilide can be produced by reacting acetic anhydride with aniline: [7]. C 6 H 5 NH 2 + (CH 3 CO) 2 O → C 6 H 5 NHCOCH 3 + CH 3 COOH. The preparation used to be a traditional experiment in introductory organic chemistry lab classes, [8] but it has now been widely replaced by the preparation of either paracetamol or aspirin, both of which teach the same practical techniques (especially ...
Morse's cited article describes the synthesis of paracetamol from 4-aminophenol and acetic acid. [6] Phenacetin may be synthesized as an example of the Williamson ether synthesis: ethyl iodide, paracetamol, and anhydrous potassium carbonate are heated in 2-butanone to give the crude product, which is recrystallized from water.

Paracetamol, [a] or acetaminophen, [b] is a non-opioid analgesic and antipyretic agent used to treat fever and mild to moderate pain. [13] [14] [15] It is a widely available over-the-counter drug sold under various brand names, including Tylenol and Panadol. Paracetamol relieves pain in both acute mild migraine and episodic tension headache.
4-Aminoacetanilide or paracetamin is a chemical compound which is a amino derivative of acetanilide and para-isomer of aminoacetanilide. There are two other isomers of aminoacetanilide, 2-aminoacetanilide and 3-aminoacetanilide. Aminoacetanilide derivatives are important synthetic intermediates in heterocyclic and aromatic synthesis. These ...
Harmon Northrop Morse (October 15, 1848 – September 8, 1920) was an American chemist. Today he is known as the first to have synthesized paracetamol, [1] but this substance only became widely used as a drug decades after Morse's death.
Remember the four P's when dealing with cold: Pets, Pipes, Plants and People (elderly and young). Bring pets inside and make sure they have plenty of food and water as well.
The Haworth synthesis is a classic method for the synthesis of polycyclic aromatic hydrocarbons. In this reaction, an arene is reacted with succinic anhydride, the subsequent product is then reduced in either a Clemmensen reduction or a Wolff-Kishner reduction. Lastly, a second Friedel-Crafts acylation takes place with addition of acid.
