Contents of the flask are poured directly into a beaker having ml ice cold water. It is an electrophilic aromatic substitution in presence of NO2, which is a Bromination of acetanilide Ask Question. Synthesis of p-bromoacetanilide from acetanilide – Labmonk. However, I still find it amazing that there is exclusively no byproduct formed. Here limiting reagent is acetanilide; hence yield shou+ld be calculated from its amount taken. Molecular formula of acetanilide = C 8 H 9 NO. Molecular formula of sulphanilamide = C 6 H 8 N 2 O 2 S. Molecular weight of acetanilide = 135 g/mole. Molecular weight of sulphanilamide = 172 g/mole. Theoretical yield: 135 g acetanilide forms 172 g.

  • In the first stage of synthesis, acetanilide is acylated by succinic anhydride, giving 4-(4-acetaminophenyl)-4-ketobutyric acid (30.2.1.3). The keto group in this compound is reduced by hydrogen in a methanol solution using palladium on carbon as a catalyst.
  • A Simple Synthesis of Stable Phosphoranes Derived from Imides or Acetanilide Derivatives. Phosphorus, Sulfur, and Silicon and the Related Elements: Vol.

The acetanilide was synthesized from phenylamine, acetic anhydride, and acetic acid. The effects of reaction time, amounts of acetic anhydride and acetic acid on the yield of acetanilide were investigated. The optimum conditions of synthesis were determined as follows: n (phenylamine) : n (acetic acid) : n (acetic anhydride) = 1: 2.0 : 0.2, reaction time was 4.5 h. The yield and purity of acetanilide was up to 98 .2 % - 98 .4 % and 99.58 % -99 .82 % respectively.
