Abstract: A method for working up liquid reaction products from the cationic polymerisation of isobutene (mainly polyisobutene (PIB), unreacted isobutene and inert diluent) involves heating and flash evaporation to give a PIB-containing liquid phase and a gas phase containing most of the unreacted isobutene and at least 30% of the inert diluent.

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.

Abstract: The halogenated methyl benzoyl cyanides are of formula (I) Ph-CO-CN , in which Ph stands for a phenyl rest substituted by chloromethyl or bromethyl that optionally carry 1-4 other rests, from halogenated methyl benzoyl chlorides having the formula (II) Ph-CO-CL. The compound having the formula (II) is reacted with a cyanide-releasing compound in the presence of a Lewis acid, optionally in an inert organic solvent, and the product obtained by this process is then isolated. The halogenated methyl benzoyl cyanides having the formula (I) are important intermediate products for the synthesys of plant protective agents.
