Hydrochloric Acid → Ethanolamine Hydrochloride

Participants

Reaction Steps

A sample of lime was slaked in a solution of ethanolamine chloride, and the resultant suspension was passed through a mesh screen to remove solid matter. The solution of ethanolamine chloride was prepared by mixing ethanolamine with concentrated hydrochloric acid, to give a 1:1.6 solution of ethanolamine hydrochloride in water. The resultant lime/ethanolamine chloride solution was treated with carbon dioxide to form precipitated calcium carbonate.
