FIELD: chemistry.
SUBSTANCE: method involves benzene alkylation by internal olefins in the presence of hydrogen fluoride and further distillation of obtained reaction mass to obtain alkylbenzene mix with the following fraction content: C16 5.0-7.0%, C17 25.0-30.0%, C18 25.0-30.0%, C19 25.0-30.0% and C20 5.0-7.0%. Then the alkylbenzene mix obtained by distillation undergoes sulfonation, and alkylbenzene solfoacids are neutralised by an alkali.
EFFECT: improved bioreduction properties together with increased cleansing capacity.
