| titleOfInvention | Method of producing pigment titanium dioxide |
| abstract | The invention relates to the technology of pigments and allows to increase the yield and improve the pigment properties of titanium dioxide when it is obtained from titanium-iron-containing raw materials. The goal is achieved by introducing carboxylic acids (mainly synthetic fatty acids), as well as ammonia solution to a pH of 3.2-3.8, into the solution obtained after the acid decomposition of the ilmenite concentrate and leaching the product with water. The organic phase is treated with sulfuric acid with a concentration of 400-800 g / l, which may also be hydrolyzed sulfuric acid, and the resulting solution is sent for thermo hydrolysis, carried out in a known manner. The resulting titanium dioxide has the following pigment characteristics: whiteness 94- 97 sm. unit; whitening ability 1750-1800 used; covering power of 35.0-37.5 g / m. The yield of titanium dioxide is 96.2-96.9%. At the same time, according to a known method, the pigment has a whiteness of 94 srv.5d, a whitening ability of 1650 srvc. units, covering power 40 g / m. The yield of titanium dioxide does not exceed 93.0-94.0%. 2 hp f-ly, 1 tab. from S9 to Co 00 O5 |
