title: [Study of the equilibrium conditions for the extractive purification of oleandomycin].
abstract: Dependence of the oleandomycin distribution coefficient on the antibiotic concentration, duration of the filtrate storage, extraction temperature and salting-out agents was studied. The distribution coefficient of oleandomycin in the system of fermentation broth filtrate--butylacetate was much lower (about 3 times) than that in the system of oleandomycin phosphate aqueous solution--butylacetate. Addition of sodium sulfate to the aqueous phase provided a significant increase in the oleandomycin distribution coefficient.
