Procedure

The zinc hydroxide precipitate was then placed into a beaker provided with a reflux condenser and 29.2 grams (0.2 Mole) of lysine was added. 100 ml ethanol was then added to this mixture and stirred and boiled at atmospheric pressure for 3 hours. The reaction mixture was then cooled and filtered yielding 35.5 grams of zinc lysinate in the form of a fine white powder.
