Method of isolation of pure free phenoxymethyl penicillin acid |
| abstract |
Solution is dealing method of isolation of pure free phenoxymethyl penicillin acid pharmacopeia liquid for purpose of abbreviating contemporaneous insulating process. This purpose is reached by washing of raw potassium salt phenoxymethyl penicillin by organic solvent selected from group of polar alcohols and ketones with amount of carbons from 1 to 4 mixed with water and after washing potassium salt is dissolved in water. Value pH of solution will be treated by diluted inorganic acid to on value 1.9, advantageous with hydrochloric acid. Product is washed by water, desiccated and used as treatment. |
