Phosphoric Acid → L-ornithine hydrofluoride phosphate

Participants

Reaction Steps

L-ornithine hydrofluoride phosphate was prepared by adding 0.1 mole hydrofluoric acid to 0.1 mole free base ornithine and then adding 0.1 mole of orthophosphoric acid. The resulting solution was concentrated in a vacuum evaporator and poured into 350 ml. of a methanol-ethanol mixture. A gummy precipitate resulted. The precipitate was then dried over calcium chloride in a desiccator. The product was L-ornithine hydrofluoride phosphate.
