Abstract: The invention relates to a method for deactivating and recovering boron trifluoride when producing polyisobutenes by means of cationic polymerization of isobutene or hydrocarbon streams containing isobutene in the liquid phase in the presence of boron trifluoride or in the form of a boron trifluoride catalyst complex. The catalyst complex is separated, essentially in the liquid phase, from the reactor discharge. The method comprises the following steps: a) removing from the polymerization reactor at -60 to 020 C., methanol, ethanol or a mixture of methanol and ethanol in such a quantity that an alcohol phase rich in boron trifluoride is formed; b) separating the alcohol phase according to (a) and, (c) optionally recycling the boron trifluoride of the alcohol phase obtained from (b) to the method in a suitable manner.

Abstract: A process for the preparation of polyisobutylenes by cationic polymerization of isobutylene or isobutylene-containing hydrocarbon streams in the liquid phase in the presence of boron trifluoride acting as catalyst, the catalytic activity of boron trifluoride being partially or completely stopped by means of a solid deactivator following a given timelapse, which deactivator is an inorganic, anhydrous or hydrous oxygen compound of aluminum which is insoluble in the reaction mixture.

Abstract: The invention relates to a method for producing polyisobutenes by means of cationic polymerisation of isobutene or hydrocarbon flows containing isobutene in the liquid phase in the presence of boron trifluoride as a catalyst. The catalytic efficacy of the boron trifluoride is partially or fully eliminated at a desired point in time by means of a solid deactivator, said deactivator being an inorganic, anhydrous, or aqueous aluminium oxide which is insoluble in the reaction mixture.

Abstract: The production of polyisobutene by liquid-phase, cationic polymerization of isobutene in the presence of a boron trifluoride catalyst followed by the addition of a solid deactivator at a required point in time uses a deactivator (I) containing boron trifluoride-binding prim., sec., tert. and/or quat. nitrogen atoms, which is insoluble in the reaction mixture. In the production of polyisobutenes (PIB) by liquid-phase, cationic polymerization of isobutene or hydrocarbon streams containing isobutene in the presence of boron trifluoride as catalyst, the catalytic activity of the BF3 is partly or completely eliminated at a required point in time by means of a solid deactivator which contains BF3-binding prim., sec., tert. and/or quat. nitrogen atoms and is insoluble in the reaction mixture.
