FIELD: sulfur-organic production. SUBSTANCE: method involves extraction of nonsulfated hydrocarbons while mixing source alcohol-aqueous solution of sodium alkylosulfate with fusel water and extraction phase of final extraction stage. The resulting mixture is divided into extraction and raffinate phases in gravity settler. The separated raffinate phase is mixed with extragent-gasoline fraction (evaporation temperature 55-105 C) in hydrodynamic nozzle at linear flow velocities in inlet nozzles ranging from 2.3 to 9.4 m/s at a frequency of flexible vibrations of flows in vortex chambers varying from 60 to 250 Hz with subsequent separation of the mixture produced after acoustic treatment into extraction and raffinate phases in packed extraction column. EFFECT: higher efficiency. 1 tbl
