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

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 obtained solution concentrate 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 1.0-2.0 g/l in cathode chamber of diaphragm electrochemical reactor, in which in anode chamber fresh water moves in counterflow, solution of active detergent constituent is prepared by processing fresh water in anode chamber of other diaphragm electrochemical reactor, into cathode chamber of which in counterflow supplied is solution of inorganic or organic acid - phosphoric, or hydrochloric, or citric, or malic - with acid concentration 1-2 g/l, with dilution to working concentration being carried out until pH value at level 6-7 is achieved and the following ratio of components (in mg/l): SAS composition and detergent constituent - not more than 200, distilled water - the remaining part.

EFFECT: method makes it possible to provide possibility of automation of the process of detergent obtaining with preservation of high washing ability of detergent and simultaneous increase of disinfecting ability of detergent.
