[Destabilization of emulsions during extraction of antibiotics from natural solutions]. / Destabilizatsiia émul'sii pri ékstraktsionnom izvlechenii antibiotikov iz nativnykh rastvorov..

Various means for changing the aggregative stability of emulsions in the system of benzylpenicillin fermentation broth filtrate and butyl acetate were tested. It was shown that the use of desemulgators was more efficient than the use of some means for removing the desemulgating admixtures. Moreover, addition of surface active substances after the preliminary thermocoagulation resulted in maximum decreasing of the emulsion aggregative stability.
