SOL CONTAINING TITANIUM DIOXIDE, ITS PRODUCTION METHOD AND PRODUCTS MADE OF IT Russian patent published in 2021 - IPC C01G23/00 C01G23/53 C01G25/00 C01G25/02 B01J21/06 B01J35/10 B01J37/03 B82Y30/00 B01J13/00 

FIELD: catalyst production.

SUBSTANCE: to obtain sol containing titanium dioxide, zirconium dioxide and/or their hydrated forms, material including meta-titanic acid is mixed in an aqueous medium with a zirconium compound or a mixture of several zirconium compounds. The specified material is a suspension or a filtrated precipitate obtained by hydrolysis of a solution containing TiOSO₄ and has H₂SO₄ content from 3 to 15 wt.% per the amount of TiO₂ contained in material. The zirconium compound is added in the amount sufficient for converting the reaction mixture into sol. The amount of sulfuric acid should not exceed the amount of the added zirconium compound in wt.% for more than 2.2 times. Sol options for the catalyst production, their application, a method for producing material in the form of particles, containing titanium dioxide, zirconium dioxide and/or their hydrated forms, material in the form of particles for the catalyst production, and its application are proposed.

EFFECT: group of inventions allows for simplification of obtaining sol containing TiO₂, while increasing stability and performance of obtaining.
