The article presents the investigation of ultrasonic treatment influence on the size of the stearylamine floccules in the aminobutyric emulsion and on the stability of received emulsions. It was found that the amine floccules in the original aminobutyric emulsion have a bimodal size distribution with small particles predominantly 900 nm and large particles with size of 5500 nm or more. It was identified that ultrasonic treatment leads to decrease the stearylamine floccules size in 13-25 times, dimensions of obtained floccules are between 35 and 220 nm. The dynamics of size changes of stearylamine floccules was studied. The stearylamine floccules were obtained in aminobutyric emulsions after the ultrasonic treatment with an intensity of 15-30 W/cm2. It was found that after ultrasonic dispersion the process of amine floccules agglomeration takes place, the duration of this effect depends on the intensity of treatment.
