Stage 2 Preparation of p-bromoacetanilide Weigh out 3g of the acetanilide you have prepared and place it in a dry 100ml conical flask, making sure that no loose crystals are sticking to the upper part of the flask. Add 15ml acetic acid and swirl the contents of the flask to obtain a clear solution. Add carefully 10ml of a 20% w/v solution of bromine in glacial acetic acid and allow the mixture to stand with occasional agitation for 15-20 minutes. Now add about 60ml cold water and stir the mixture. Wait 5 minutes for the precipitated product to become filterable and filter under suction.
