Abstract: 1,139,862. Purification of basic antibiotics. CHAS. PFIZER & CO. Inc. 14 Feb., 1967, No. 7111/67. Heading C2A. Inorganic cations are removed from a basic antibiotic which has been adsorbed on a particulate carboxylic acid-type cation exchange resin, by contacting the resin adsorbate with an aqueous solution of pH 4À0 to 7À5, treating the effluent from said resin adsorbate with a second particulate cation exchange resin in the hydrogen form, recycling the effluent from said second resin into contact with the first resin adsorbate and continuing said cycling until the adsorption of said inorganic cations upon said second resin is substantially complete. It is preferred that the second resin be of the sulphonic acid type, e.g. a sulphonated copolymer of styrene together with 8 to 20% of divinyl-benzene. The basic antibiotic is recovered from the first resin bed by elution with strong aqueous acid, e.g. H 2 SO 4 . After neutralization of the excess H 2 SO 4  in the eluate, the polyvalent inorganic cations are removed by precipitation with sodium oxalate. Alternatively, a final purification to remove polyvalent inorganic cations may be obtained by treatment with an aqueous solution of a sequestering agent which may be applied before, or after, or in combination with the above process. In the latter case, the sequestering agent is incorporated in the aqueous solution of pH 4À0 to 7À5 used in step one of the aforesaid process. A preferred sequestering agent is ethylene diamine tetra-acetic acid sodium salt. Basic antibiotics which may be so purified are streptomycin, neomycin, viomycin, dihydrostreptomycin, hydroxystreptomycin, streptothricin, mannosidostreptomycin and polymyxin.
