Preparation of ethyl iodoacetate
Ethyl iodoacetate can not be prepared directly by esterification of iodoacetic acid with ethyl alcohol but it could be prepared by reacting potassium iodide with ethyl chloroacetate or ethyl bromoacetate.
In the round bottom flask with reflux condenser 25 g of ethyl chloroacetate are dissolved in 150 ml ethyl alcohol. To alcoholic solution the solution of 35 g of potassium iodide in 25 ml distilled water is dropwise added. The mixture is stirred and gently heated at 40-50° C. After 1-2 hours the reaction is complete and the mixture is transferred to a separatory funnel with water. The oily layer is separated, dried over calcium chloride and distilled. Ethyl iodoacetate is a colorless, dense liquid boiling at 179° C. Ethyl iodoacetate is sensitive to light and should be stored in a dark place in order to prevent decomposition.
