METHOD OF WATER PHASE AND MOTHER LIQUORS TREATMENT DURING PHENOXYMETHYLPENICILIN OR BENZYL PENICILIN PRODUCTION

摘要

Solution is release to improved elaborating of liquid waste after processing of potassium salts of benzylpenicillin and phenoxymethylpenicillin, when by treatment of mother liquors by phosphoric acid at the presence of acetone is gained crystalline dihydrogen-potassium-phosphate. After its separation is by adjustment of pH level of mother liquors by hydroxide or carbonate hydrogen sodium is gained by cooling of trihydrate sodium acetate. Used acetone is regenerated by distillations. Yielded liquid waste is submitted to biologic cleaning under substantially improved conditions, by which is raised economical and ecological contribution of processing of potassium salts of penicillin.
