Abstract:
The invention relates to a method for producing tertiary amines based on polyisobutene polymers by reacting polyisobutene alcohol, optionally in admixture with polyisobutene aldehyde, with at least one secondary amine in the presence of at least one heterogeneous catalyst which has a nickel content, calculated as NiO, of less than 50% by weight. The invention also relates to a method for producing quaternized polyisobutene ammonium compounds from the tertiary polyisobutene amines obtained, using a quaternizing agent. The polyisobutene amines or quaternized polyisobutene ammonium compounds are used as fuel additives, in particular in diesel engines with common rail injection systems.
