title: [Stability of rifamycin B in aqueous solutions].
abstract: Stability of rifamycin B in aqueous solutions at various values of pH and temperature was studied. It was shown that inactivation of the antibiotic in neutral and alkaline solutions proceeded according to the first order equation. In acid solutions rifamycin B was oxidized with air oxygen to form rifamycin O.
