Изобретение относится к методам получения дисперсных окислов, в частности диоксида титана, и может быть использовано при производстве пигментов для различных отраслей промышленности например лакокрасочной. Использование изобретения позволяет повысить содержание рутила в целевом продукте до 95% и выше при одновременном упрощении конструкции плазмохимического реактора и снижении энергозатрат. Способ включает генерацию плазмы кислорода или кислородсодержащего газа, смешение исходных реагентов при соотношении молярных расходов кислорода и тетрахлорида титана, равном 0,05 - 1,2 при этом тетрахлорид титана в жидком состоянии вводят в плазменный поток с температурой 2500 - 3500°С. Перед охлаждением продуктов реакции в теплообменнике осуществляют их закалку, при этом охлаждение продуктов реакции осуществляют до температуры, не превышающей 0,7Tр, где Tр = (1100 - 1500)°С, - температура продуктов реакции на входе в закалочную камеру.The invention relates to methods for producing dispersed oxides, in particular of titanium dioxide, and can be used in the manufacture of pigments for various industries, such as paint and varnish. The use of the invention allows to increase the content of rutile in the target product to 95% and above while simplifying the design of the plasma-chemical reactor and reducing energy consumption. The method involves the generation of oxygen plasma or oxygen-containing gas, mixing the initial reagents with a ratio of molar oxygen consumption and titanium tetrachloride equal to 0.05 - 1.2, while the titanium tetrachloride in the liquid state is introduced into a plasma stream with a temperature of 2500 - 3500 ° C. Before cooling the reaction products in a heat exchanger, they are quenched, while cooling the reaction products to a temperature not exceeding 0.7T p , where T p = (1100 - 1500) ° C, is the temperature of the reaction products at the entrance to the quenching chamber.
