Mono substituted products of primary amine cannot prepared easily by direct action of a reagent. Bromination of acetanilide gives para brominated acetanilide mainly, because amino group of acetanilide is protected by acetyl group. To prepare p-bromoacetanilide from acetanilide by Bromination reaction. Bromination is an electrophilic substitution reaction on an aromatic ring. Used as analgesic and antipyretic. Glacial acetic acid 70 ml. Sodium bisulphite sufficient quantity.

The bromine solution is added slowly with constant stirring to acetanilide solution and the flask is placed in cold water as the reaction is exothermic. When addition of all the bromine is complete the solution turns orange due to the presence of slight excess of bromine, then allowed to stay at room temperature for 30 min.

Contents of the flask are poured directly into a beaker having ml ice cold water. The conical flask is further rinsed with 50 ml cold water and transferred into the beaker with stirring. Here para bromo acetanilide separates as a white solid.

If the colour of the solution is persistently yellow, about g of sodium bisulphite is added with constant stirring to bleach coloration. The crude product is filtered with suction, the residue washed with cold water, recrystallized from rectified spirit, dried in an oven at o C and bromunation percentage yield is calculated.

Synthesis of p-bromoacetanilide from acetanilide

The p-bromo acetanilide is obtained as colourless crystals, m. Therefore, 10 g of acetanilide would give…………………. X g of p-bromo acetanilide.

The yield of synthesized p-bromo acetanilide was found to be When an ethanolic solution containing acetone and its two equivalents of benzaldehyde is made alkaline with sodium hydroxide, rapid Aniline undergoes nucleophilic substitution with bromine, even in cold.

The bromine atoms enter at the two ortho positions and Here nitration is occurring on nitrobenzene. It is an electrophilic aromatic substitution in presence of NO2, which is a Here alcohol group of benzoin is oxidized to ketone group forming benzil in the presence of concentrated nitric acid Complete hydrolysis can be rapidly obtained, if the ester is boiled under reflux with a dilute aqueous solution of Alkaline hydrolysis of esters is called saponification and is an irreversible process.

Here one mole of methyl salicylate acetanilidf of We Labmonk, some scientific researchers unite to design a platform for getting sources of different lab protocols and discuss various research related issues. Home Synthesis of p-bromoacetanilide from acetanilide.
