the purity of the institute is the first to experience the purity of the two manufacturing methods.

摘要

according to the invention, the purity and the purity of TiCl 4. experience in manufacturing TiO 2 in order from the purity of TiCl 4. along the road, the second in TiO manufacturing method.;expansion, the purity of cooling water TiCl 4 equipped with a distillation group 130 degrees - 160 degrees, the temperature in a primary distillation, distillation, then the purity of the TiCl at 70 degrees ~ 4 degrees increased from 100 to the file at the same time, and the purity of the TiCl4 to light TiCl 4 aqueous solution produced from a after the 6N - NH4OH add aqueous solution, ph 7 and at the same time, the degree of mixing is enough water to Ti (OH 4) manufacturing in the Ti (OH 4) precipitation in the organic solvent is methanol, propane will be heterogeneous, methyl ethyl ketone (ubd80ud53cube44) ratio of 1: 1 a, ~ 4 yuan much of the V2O 5, and the powder Ti (OH) 4, the car of 3 ~ 10 hours dispersion.at the same time, the stirring Ti centrifuge in sikkim (OH) 4 solution, precipitation and separation of Ti (OH) about 70 degrees in the four sediment dehydrated after 24 hours to 800 degrees for three hours in the station, along the road, two of the TiO manufacturing, as a feature.
