METHOD OF OBTAINING DETERGENT Russian patent published in 2015 - IPC C11D11/00 C11D1/04 C11D1/62 

FIELD: chemistry.

SUBSTANCE: invention relates to improved method of obtaining detergent, including preparation of water solution of SAS composition based on quaternary ammonium compound, preparation of water solution of active detergent constituent based on acid compounds, mixing water solution of SAS composition and solution of active detergent constituent and dilution of mixture to working concentrations. Water solution of SAS composition is prepared by processing solution of quaternary ammonium compound in distilled water with concentration by dry substance 2.0-5.0 g/l in cathode chamber of diaphragm electrochemical reactor, solution of active detergent constituent is prepared by processing in anode chamber of the same reactor of solution of inorganic acid - phosphoric or hydrochloric - or organic acid - citric or malic- with concentration of acid 2-10 g/l, with dilution of mixture to working concentrations being carried out until pH value at the level 6-7 and content of SAS composition and detergent composition not higher than 200 mg/l are achieved.

EFFECT: method makes it possible to reduce labour consumption and automate process of obtaining detergent with preservation of high washing activity and disinfecting ability of detergent at satisfactory level.
