METHOD OF PRODUCING LOWER TITANIUM CHLORIDES IN MIXTURE OF MOLTEN METAL CHLORIDES AND DEVICE TO THIS END Russian patent published in 2009 - IPC C01G23/02 

FIELD: chemistry.

SUBSTANCE: invention relates to production of lower titanium chlorides, used as flux for removing impurities from magnesium or magnesium alloys. The method of producing lower titanium chlorides in a mixture of molten metal chlorides involves pouring a mixture of molten chlorides into an apparatus, addition of spongy metallic titanium, addition of titanium tetrachloride, extraction of non-chlorinated residue. The mixture of molten metal chlorides is loaded under a flow channel of argon. Excess pressure of 0.005-0.25 MPa is created in the apparatus and titanium tetrachloride is added while stirring continuously. The obtained melt of lower titanium chlorides is kept for 0.5 hours. After removing the melt of lower titanium chlorides, the apparatus with non-chlorinated residue is cooled. The solid non-chlorinated residue is removed from the reactor, crushed and separated into metallic and salt components. The metallic component is taken to the stage for loading spongy metallic titanium, and the salt component is added to the mixture of molten metal chlorides. A device is also proposed for production of lower titanium chlorides.

EFFECT: high quality of obtained melt of lower titanium chlorides due to reduced content of iron, increased total content of bi- and trivalent titanium, as well as recycling of non-chlorinated residue for further use.
