  • Process for the preparation of trimethyl metal compounds
    Patent number: 10160774
    Abstract: Process for the production of a trimethyl metal compound with the formula M(CH3)3, said process comprising the steps of (i) reacting a metal trihalide MX3 with a trialkyl aluminium compound AI(R)3 to form a trialkyl metal compound M(R)3 and a dialkyl aluminium halide AI(R)2X, and (ii) reacting said trialkyl metal compound M(R)3 with either trimethyl aluminium [AI(CH3)3] or dimethylaluminium halide [AI(CH3)2X] to form said trimethyl metal compound M(CH3)3, wherein M is selected from the group consisting of Ga and In, X is a halogen, and R is a linear or branched alkyl group with 2 to 8 carbon atoms.
    Type: Grant
    Filed: August 25, 2016
    Date of Patent: December 25, 2018
    Assignee: AKZO NOBEL CHEMICALS INTERNATIONAL B.V.
    Inventors: Mabel Andrea Caipa Campos, Glen Rosini, Richard Herman Woudenberg, Andy Kurniawan, Marcellinus Antonius Maria Te Nijenhuis

  • Treatment of a titanium tetrachloride-containing waste stream
    Patent number: 7045480
    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.
