Page 50 - ... introduced in a moderate stream. The flask is set in a vessel with water to keep it cool. The acid is rapidly absorbed, and, after about 45 minutes, the esters separate, floating in the solution, and no more hydrochloric acid is absorbed. The current of gas is now stopped, and the flask allowed to stand for half an hour to complete the reaction. The liquid is diluted with about 5 times its volume of water and boiled until the acid solution is clear, the esters, with...
