Potassium Hydroxide → L-(-)-Ornithine

Participants

Reaction Steps

Into the reaction apparatus used in Example 1, 160 g of ethyl alcohol, 16.8 g of ornithine hydrochloride and 5.6 g of potassium hydroxide were added. The resulting mixture was reacted for 3 hours, refluxing the solvent, while being stirred. After the reaction was over, the resultant product was cooled to room temperature and then the by-product potassium chloride was filtered off. Then the solvent was distilled off from the resultant product under reduced pressure to obtain 13.0 g of ornithine in a syrupy state.
