More Information
Summary:A reactor for producing finely divided particles of rutile titanium dioxide including a cylindrical reaction chamber, an outwardly diverging frusto-conical duct having an oxidizing gas inlet at its narrow upstream end and a length of between 0.5 and 10 times the diameter of the reaction chamber, an annular slot for introducing titanium tetrachloride into the device at an angle of 0 DEG to 45 DEG to a perpendicular to the longitudinal axis of the reactor, the slot being located downstream of the divergent duct, the reaction chamber being downstream of the slot and coaxial with the divergent duct. The invention is also related to a method of producing titanium dioxide by oxidizing titanium tetrachloride in a reactor of the type above described.
