Title: Improved process of extracting penicillin and product of said process
IPC: A61K31/43
Filed: 1945-02-23
Abstract: Penicillin is obtained from aqueous media or culture media containing penicillin in a relatively crude state by adding thereto a watersoluble neutral inorganic salt, e.g. a water-soluble neutral ammonium salt such as ammonium sulphate, adjusting the pH of the mixture to within the range of 4.3 and 4.85, e.g. with a mineral acid such as phosphoric or sulphuric acid, and extracting at room temperature with a liquid ester of an organic carboxylic acid which is incompletely soluble in the mixture, the amount of said salt being sufficient to substantially reduce the distribution ratio of the penicillin between the water and the ester of the organic carboxylic acid.  In an example, ammonium sulphate and amyl acetate are added to a filtered broth containing penicillin, the pH adjusted with phosphoric acid and the penicillin is extracted from the amyl acetate layer.  Other suitable esters for the process of the invention are ethyl-, propyl-, isopropyl-, butyl-, isoamyl and isobutyl acetate, ethyl-, propyl-, amyl-, isoamyl- and butyl propionate and ethyl oxalate. Any water-soluble neutral inorganic salt may be used to replace in whole or in part the ammonium sulphate in the above example, e.g. sodium sulphate, sodium chloride, magnesium sulphate, ammonium p  chloride or calcium chloride may be used.
