METHOD OF PRODUCING COLLOIDAL SOLUTION OF TITANIUM TRISULPHIDE WITH ANTIMICROBIAL PROPERTIES Russian patent published in 2020 - IPC C01G23/00 C01G1/12 B01J13/00 A01P1/00 A01P3/00 C02F1/50 C09K17/02 B82B3/00 

FIELD: manufacturing technology.

SUBSTANCE: invention can be used in treating soil, porous structures and waste water in order to suppress activity of pathogenic microorganisms. To obtain colloidal solutions of titanium trisulphide in deionised water, having antimicrobial activity, synthesis of titanium trisulphide from metallic titanium and powder of elemental sulfur, taken in stoichiometric ratio according to reaction Ti+3S=TiS₃. Metal titanium and elementary sulfur powder are sealed in quartz ampoules in vacuum of not less than 10^-3 bar. Synthesis is carried out in a tubular furnace for 24 or 48 hours at temperatures from 450 to 500 °C at temperature gradient. Resulting crystals are dispersed in deionised water in concentration from 0.001 to 0.01 g/l with ultrasound treatment. Then, before use dispersion top part is centrifuged and separated.

EFFECT: invention enables to obtain an antimicrobial solution without using wide-spectrum antibiotics, with the possibility of long-term storage of the powdered component before preparing the dispersion, and reduces harm to the environment.
