Abstract
We have studied the preparation of titanium trichloride solutions by reducing aqueous titanium tetrachloride solutions with metallic aluminum. The results demonstrate that aqueous titanium tetrachloride solutions have higher reactivity with metallic aluminum than does pure titanium tetrachloride. The highest stability is offered by solutions prepared from aqueous 25 to 40% titanium tetrachloride solutions. We have examined how the temperature and time of the reduction of aqueous titanium tetrachloride solutions influence the titanium trichloride yield and assessed the feasibility of preparing aqueous titanium trichloride solutions using aluminum waste (incineration plant slag) as a raw material. In our experiments, we have obtained combined samples of titanium trichloride solutions that can be used as catalysts or reagents in water purification processes.
