Abstract: The mixture described is a mixture of isomeric nonanol diesters of a dicarboxylic acid, selected from the class consisting of a mixture of diesters of adipic acid in the 1H NMR spectrum of which, observed in CDCl3, the ratio of the area under the resonance signals at chemical shifts in the range from 1.0 to 2.0 ppm with respect to TMS to the area under the resonance signals at chemical shifts in the range from 0.5 to 1.0 ppm with respect to TMS is from 1.20 to 5.00 and a mixture of diesters of phthalic acid, in the 1H NMR spectrum of which, observed in CDCl3, the ratio of the area under the resonance signals at chemical shifts in the range from 1.1 to 3.0 ppm with respect to TMS to the area under the resonance signals at chemical shifts in the range from 0.5 to 1.1 ppm with respect to TMS is from 1.00 to 4.00.The diesters of adipic and phthalic acid are suitable as plasticizers for PVC-based molding compositions and have high compatibility, a low cold crack temperature, low torsional rigidity and/or high thermal stability.

Abstract: The invention relates to a method for shutting down a reactor used to oligomerize alkenes on a heterogeneous catalyst containing nickel. According to the inventive method, the amount of alkenes in the feed stream to the reactor is decreased by using a hydrocarbon flow which is substantially devoid of aromatic compounds. The amount of alkenes in the feed stream to the reactor is reduced to less than 10 % wt. % of the total feed stream so that the temperature of the catalyst does not exceed or does not substantially exceed the maximum temperature of the catalyst in a productive operational mode before the shut down occurs. The hydrocarbon flow which is substantially devoid of aromatic compounds and which is used partially or fully is the flow which is retained when the oligomer products are separated from the reactor discharge.

Abstract: The invention relates to a method for producing essentially unbranched octenes and dodecenes by oligomerising flows of hydrocarbons containing butene-1 and/or butene-2 and butane, said hydrocarbon flows being essentially free of isobutene, at temperatures of 30 to 280 DEG C and at a pressure of 10 to 300 bar over a heterogenous catalyst containing nickel. According to the invention, sufficient quantities of the butane which has separated from the reaction mixture and sufficient quantities of non-reacted butene are reintroduced into the oligomerisation reaction to ensure that the maximum quantity of oligomers contained in the reacted reaction mixture does not exceed 25 wt. % in any part of the reactor or if a reactor cascade is used, in any part of the cascade.

Abstract: The invention describes a process for the preparation of novel surfactant alcohols and surfactant alcohol ethers by derivatization of olefins having from about 10 to 20 carbon atoms or of mixtures of such olefins to give alkanols, and optional subsequent alkoxylation, which comprises subjecting a C 4 -olefin mixture to metathesis, dimerizing the resulting olefins, and then derivatizing them to give surfactant alcohols, and optionally alkoxylating said alcohols. The olefin mixture obtained in the dimerization has a high proportion of branched components and less than 10% by weight of compounds which contain a vinylidene group. invention further describes the use of the surfactant alcohols and surfactant alcohol ethers to give surfactants by glycosylation or polyglycosylation, sulfation or phosphation.

Abstract: Catalysts containing copper as an active component ,and used in the hydrogenation of methylol-aldehydes to methylol-alcohols, are regenerated in an oxygen-containing medium and activated prior to re-use in a hydrogen-containing medium. An Independent claim is included for use of the catalyst regeneration process is in the hydrogenation of hydroxypivalaldehyde, 2,2-dimethylolbutanal, 2,2-dimethylolpropionaldehyde, 3-hydroxypropionaldehyde and/or trimethylolacetaldehyde.

Abstract: The invention relates to a mixture of diesters of a dicarboxylic acid and isomeric nonanols. Said mixture is selected among a mixture of adipic acid diesters in whose 1H-NMR spectrum, obtained in CDCl3, the ratio of the surfa ce area below the resonance signals in case of chemical shifts of between 1.0 a nd 2.0 ppm towards TMS to the surface area below the resonance signals in case of chemical shifts of between 0.5 and 1.0 ppm towards TMS is between 1.20 and 5.00. Alternatively said mixture is selected among a mixture of phthalic aci d diesters in whose 1H-NMR spectrum, obtained in CDCl3, the ratio of the surfa ce area below the resonance signals in case of chemical shifts of between 1.1 a nd 3.0 ppm towards TMS to the surface area below the resonance signals in case of chemical shifts of between 0.5 and 1.1 ppm towards TMS is between 1.00 and 4.00. The above adipic and phthalic acid diesters are suitable for use as softeners for moulding materials on a PVC basis and characterized by high compatibility, low brittleness temperature, low stiffness in torsion and/or high thermal stability.

Abstract: The invention relates to a method for oligomerising C2- to C8 olefins on a heterogeneous catalyst containing nickel. Said method comprises the following steps: i) a catalyst pre-treatment phase in which the catalyst is brought into contact with a first hydrocarbon mixture which has an olefin content of less than 50 wt. % and contains less than 0.1 wt. % diolefins and alkines; and ii) an essentially stationary working phase in which a stream of a second hydrocarbon mixture, which contains 50 to 100 wt. % C2- to C8 olefins and less than 10 wt. ppm diolefins and alkines, is brought into contact with the catalyst.
