METHOD OF PRODUCING TITANIUM DIOXIDE Russian patent published in 2012 - IPC C09C1/36 C01G23/53 C09C3/10

Abstract RU 2444550 C2

FIELD: chemistry.

SUBSTANCE: method of producing titanium dioxide involves reaction of tetrabutoxytitanium with a surfactant and a precipitating component - ethyl alcohol. The surfactant used is polyoxyethylated (7) hydrogenated castor oil or polyoxyethylated (10) isooctylphenol. First, tetrabutoxytitanium and the surfactant are mixed, after which ethyl alcohol with 4 vol. % water is added, followed by stirring, holding and gelation. Calcination is then carried out while gradually heating to 300°C and holding for 50 hours.

EFFECT: invention enables to obtain titanium dioxide with average particle size of 0,071-0,091 mcm with glase properties which provide lustre.
