    Abstract: PCT No. PCT/EP95/04463 Sec. 371 Date May 6, 1997 Sec. 102(e) Date May 6, 1997 PCT Filed Nov. 14, 1995 PCT Pub. No. WO96/16023 PCT Pub. Date May 30, 1996Halomethylbenzoyl cyanides I PH-CO-CN (I) where Ph is phenyl which is substituted by chloromethyl or bromomethyl and may cary 1-4 other rradicals, are prepared from halomethylbenzoyl chlorides II PH-CO-Cl (II), by reacting II with a cyanide-donating compound in the presence of a Lewis acid, if required in an inert organic solvent or diluent, and then isolating the product. The halomethylbenzoyl cyanides I are important intermediates for synthesizing crop protection agents.

    Abstract: Precipitation method involves utilizing a non-polar solvent or solvent mixtures. The solution is removed with a polar solvent selectrd from hydroxyl group containing compound, has a general formula (I) and carbonyl group containing compound has general formula (II). The precipitated polymer is isolated. A replacement with the polar solvents and the separation of volatile solution components from the polymers are carried out by degassing in a stirred tank, kneading machine, thin film vaporizer, falling film evaporator or coil tube evaporator. The hydroxyl group containing compound having general formula (I), is R1>(O-A)n-OH. R1>H, 2-20C alkyl or alkenyl residue, 5-20C cycloalkyl residue or 6-20C aryl, alkyl aryl or aryl alkyl residue; A : 2-4C alkylene; and n : 0-10. The carbonyl group containing compound having general formula (II) is R2>-CO-X-R3>. R2>H, 2-20C alkyl or alkenyl residue, 5-20C cycloalkyl residue or 6-20C aryl, alkylaryl or arylalkyl residue; X : S or O and R3>2-20C alkyl or alkenyl residue, 5-20C cycloalkyl residue or 6-20C aryl, alkylaryl or arylalkyl residue.

    Abstract: A process is disclosed for preparing halogenated methyl benzoyl cyanides having the formula (I): PH-CO-CN, in which Ph stands for a phenyl rest substituted by chloromethyl or bromomethyl that may 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 or diluent, 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 synthesis of plant protective agents.

    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 invention relates to a method for deactivating and recovering boron trifluoride when producing polyisobutenes by means of cationic polymerisation 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. Said catalyst complex is separated, essentially in the liquid phase, from the reactor discharge. Said method contains the following steps, a) removing from the polymerisation reactor at -60 to 0 ~C, methanol, ethanol or a mixture of methanol and ethanol in such a quantity that an alcohol phase rich in boron trifluoride is deposited b) separating the alcohol phase according to (a) and, (c) from the alcohol phase according to (b) is reintegrated into the inventive method in a suitable manner if desired.

    Abstract: The invention relates to a method for producing polyisobutenes by means of cationic polymerisation of isobutene or hydrocarbon flows containing isobute ne 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.
