WebAcetanilide was used as a precursor in penicillin synthesis and other pharmaceuticals and its intermediates. Acetanilide has analgesic and fever-reducing properties; it is in the same class of drugs as acetaminophen (paracetamol). Under the name acetanilid it formerly figured in the formula of a number of patent medicines and over the counter ... Acetanilide can be produced by reacting acetic anhydride with aniline: C6H5NH2 + (CH3CO)2O → C6H5NHCOCH3 + CH3COOH The preparation used to be a traditional experiment in introductory organic chemistry lab classes, but it has now been widely replaced by the preparation of either paracetamol or aspirin, both of which teach the same practical techniques (especially recrystallization of the product) but which …

Bromination of Acetanilide: Mechanism & Explanation

WebAcetanilide itself is non-polar solvent whereas ethanol on the other hand is polar; therefore ethanol when singly used is not a good solvent.
