In terms of how acetanilide is synthesized, it's most commonly made byreacting aniline with either acetyl chloride or acetic anhydride. Although both methods work equally well, the preparation from acetic anhydride tends to be preferred due to the corrosiveness and toxicity of acetyl chloride. Why...

and the price of acetic acid was approaching the cost line, causing the price of acetic acid to stop falling and rise; On the supply side, some acetic anhydride manufacturers had suspended operations, supply of acetic anhydride tightened, and had a strong upward momentum for acetic anhydride. ...
Chemical N-acetylation reactions contained sacculi (OD600 = 3.4) or isolated cell walls (2–5 mg/ml), resuspended in 1 mL of saturated NaHCO3, and 2% acetic anhydride. After 1 h on ice, the reactions were allowed to warm to room temperature overnight. After incubation at ...
Product Name: Acetic acid, anhydride with N-[[(5R)-3-[4-(3,4-dihydro-4-oxo-1(2H)-pyridinyl)-2,3,5-trifluorophenyl]-2-oxo-5-oxazolidinyl]methyl]-N-3-isoxazolylphosphoramidic acid Synonyms: Acetic acid, anhydride with N-[[(5R)-3-[4-(3,4-dihydro-4-oxo-1(2H)-pyridinyl)-2,3...
Permethylation was performed according to the method of Ciucanu and Kerek,50 with modifications to limit oxidative degradation.51 Where indicated, peracetylation of the fermentation products was achieved with acetic anhydride: pyridine (1:1 v/v, 60 °C, 20 min) as described previously.49 ...
Acetic anhydride, orethanoic anhydride, is the chemical compound (CH3CO)2O. Commonly abbreviated Ac2O, it is the simplest isolable anhydride of a carboxylic acid and is widely used as a reagent in organic synthesis. It is a colorless liquid that smells strongly of acetic acid, formed by its...
