Synthesis of p-nitroacetanilide from acetanilide 12 sep 2015 this is another lab report dug up from the archives of lab reports for the fun of it. Search results for acetanilide at sigma-aldrich acetanilide for synthesis 4-nitro-3-(trifluoromethyl)acetanilide.
The total synthesis of sulfanilamide from benzene can be carried out in six steps using benzene nitrobenzene aniline acetanilide 4-acetamidobenzene-sulfanyl chloride. In the second step p-nitroaniline is prepared from p-nitro acetanilide due to hydrolysis of acetate ion synthesis of p-nitroaniline from acetanilide. In this video, i will be synthesizing p-nitroaniline from acetanilide this chemical is used mainly as a precursor for a dye, but it can also be used in an i.
Nitration of acetanilide (lab report) nitration is a type of chemical reaction which a nitro group is added to/substituted in a molecule basically it can be carried out by a mixture of concentrated nitric acid and sulphuric acid mixture is useful to obtain the active nitronium ion. Acetanilide undergoes ready nitration, giving chiefly the colorless p-nitroacetanilide, mixed with a much smaller proportion of the yellow o-nitroacetanilide recrystallization from ethanol readily removes the more soluble ortho compound, and the pure p-nitroacetanilide can then be hydrolyzed to p-nitroaniline.
