FIELD: production of linear alkylbenzenesulfonates.
SUBSTANCE: production method includes alkylation of benzene with internal olefins in presence of hydrogen fluoride, subsequent sulfonation of alkylbenzenes with gaseous SO3 and neutralization of the obtained alkylbenzenesulfonic acids with alkali, and a mixture of linear alkylbenzenes LAB18,19,20 is taken for alkylation at the following ratios between homologues (% of mass): LAB18 - 5-15, LAB19 - 55-65, LAB20 - the rest up to 100.
EFFECT: high degree of complete biodegradability of linear alkylbenzenesulfonates.
