Abstract
In case of the pyrogenous production of metal oxides or metalloid oxides, whenever a halogen compound is used as a starting material, an elementary halogen is formed as a byproduct. This may be converted in the cooling section of the reaction apparatus with hydrogen into hydrogen halide. For a better temperature control and prevention of uncontrolled deflagration of the hydrogen in case of the halogen detonating gas reaction, according to the invention the hydrogen is introduced into the cooling section by means of a double jacket pipe, whereby an inert gas is introduced additionally by way of the interstice between the inside wall and the outside jacket of the double jacket pipe into the cooling section.
