  • Treatment of a titanium tetrachloride-containing waste stream
    Publication number: 20050084433
    Abstract: The invention relates to a process to increase the amount of TiCI4 that is retrieved from a waste stream comprising one or more titanium (halo)(alk) oxides while also reducing the quantity and/or hazard of the resulting waste. Valuable solvents/diluents and/or alkyl halides that are introduced into or formed during the process can also be retrieved. The so obtained TiCI4, solvents/diluents and/or alkyl halides are recyclable to, for instance, the process to make Ziegler-Natta catalysts and or co-catalysts.
