Abstract: A polyisobutene composition is disclosed with a global maximum for the differential molecular weight distribution curve at a molecular weight Mmax of 3500 to 8000, with at last one local maximum at a molecular weight of 112 to 560. The isobutene oligomers present are flow and boiling auxiliary agents. They are applied to high molecular weight isobutene polymers, preferably before or during a distillation, to remove non-reacted isobutene and/or an inert solvent.

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: A process for removing impurities from 3-(2'-acetoxyethyl)-dihydro-2(3H)-furanone (I), which comprises initially preparing the 3-(2'-acetoxyethyl)-dihydro-2(3H)-furanone containing the undesirable impurities in a manner known per se by acetylating 3-(2'-hydroxylethyl)-dihydro-2(3H)-furanone, subsequently treating it with strong mineral acids and finally removing the decomposition products of the undesirable impurities from I.

Abstract: A process is disclosed for producing isomer mixtures from Ophenoxyalkylhydroxyl amines Ia: H2N-O-CH2-CH(R1)-O-Ar and Ib: H2N-O-CH(R1)-CH2-O-Ar (wherein R1 represents alkyl, Ar where appropriate a substituted phenyl) and the corresponding salt mixtures. This process involves the following steps: (a) an isomer mixture of O-(2-hydroxyethyl)-oximes (IIa) and (IIb) (in which R2 is an alkyl and R3 is an alkyl or alkoxy, or R2 and R3 together with the common C atom form a 5-7 member ring) is converted by reaction with a sulphonyl halogenide of formula (III): Hal-SO2-R4 (wherein R4 represents an organic group and Hal is a halogen) in the presence of a base to form the corresponding sulphonate mixture of (IVa) and (IVb); (b) this sulphonate mixture is reacted in the presence of a base with a phenol of formula (V): HOAr to produce a mixture of O-phenoxyalkyloximes of general formulae (VIa) and (VIb); (c) the mixture is hydrolysed in the presence of an acid and, if required, (d) the O-phenoxyalkylhydroxyl amines (Ia) and (Ib) are released from the resulting salts using a mineral base. The O-phenoxyalkylhydroxyl amines (Ia/Ib) and their precursors (VIa/VIb) are important intermediate products for plant protective agents and drugs.

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.
