Preparation of ethyl chloroacetate

Ethyl chloroacetate is prepared by the action of ethyl alcohol on monochloroacetic acid in presence of sulfuric acid.

Preparation of ethyl chloroacetate

Preparation of ethyl chloroacetate

To the round bottom flask fitted with a reflux condenser and stirrer 75 g of monochloracetic acid, 45 g of 95% ethyl alcohol and 10 g of concentrated sulfuric acid are added. The reaction flask is gently heated at 100° C and refluxing was continued for about 5-6 hours. At the end of the reaction the flask is allowed to cool and then poured into a separatory funnel containing cold water. The ethyl chloroacetate layer is separated, washed several times with water, dried with calcium chloride and then fractionally distilled by collecting the fraction passing over between 40.5-45.0° C. Ethyl chloroacetate is a colorless liquid having an odor of fruit and boils at boiling at 143.5° C. It is insoluble in water, but easily soluble in the common organic solvents.
