    Abstract: An oligomerization catalyst for olefins having from 2 to 6 carbon atoms is produced by treating aluminum oxide with a nickel compound and a sulfur compound, either simultaneously or firstly with the nickel compound an then with the sulfur compound, and subsequently drying and calcining the resulting catalyst, wherein a molar ratio of sulfur to nickel in the finished catalyst of from 0.25:1 to 0.38:1 is set in this way. The catalyst and its use are also described.

    Abstract: Polyisobutenylphenol-containing Mannich adducts are prepared by a) alkylation of a phenol with highly reactive polyisobutene at below about 50° C. in the presence of an alkylation catalyst; b) reaction of the reaction product from a) with formaldehyde, an oligomer or a polymer of formaldehyde and at least one amine which has at least one secondary amino function and no primary amino function, or c) reaction of the reaction product from a) with at least one adduct of at least one amine which has at least one secondary or primary amino function and formaldehyde, an oligomer of formaldehyde, a polymer of formaldehyde or a formaldehyde equivalent, and are used as detergent additives in fuel and lubricant compositions, and additive concentrates, fuel compositions and lubricant compositions contain these Mannich adducts.

    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.
