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 300C 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. ^ 1 tbl, 2 ex |
