[Ways to optimize the technological process of oleandomycin reextraction].

Dependence of the oleandomycin distribution coefficient on pH of the acqueous phase and temperature in the system of butylacetate extract-water acidified with orthophosphoric acid was studied. With a purpose of intensification of the process of oleandomycin reextraction, decreasing the antibiotic inactivation and evaporation of the organic solvent it was proposed to perfom oleandomycin extraction at pH 4.0--5.0 accompanied by simultaneous decreasing of the temperature.
