L-Lysine → Cobalt lysinate

Participants

Reaction Steps

The recovered cobalt hydroxide was then placed into a beaker provided with a reflux condenser and Dean Stark water trap. 29.2 grams (0.2 Mole) of lysine was added and thereafter 100 ml hexane was subsequently added and stirred and boiled at atmospheric pressure for 3 hours. In the course of reaction about 3.6-3.8 ml of water was removed from the reaction media and acquired in the Dean Stark apparatus. The reaction mixture was then cooled and filtered yielding 35 grams of cobalt lysinate in the form of a fine pink powder.
