Patent ID: 8821842

Claim:
An isoalkane mixture whose 1 H NMR spectrum in the region of a chemical shift δ of from 0.6 to 1.0 ppm, based on tetramethylsilane, has a surface integral of from 25 to 70%, based on the total integral surface, wherein a fraction of side chains having two or more carbon atoms, from among all side chains of the longest continuous carbon chain of the isoalkane molecules in the isoalkane mixture, is less than 20%, wherein the isoalkane mixture comprises at least 70% by weight of alkanes having 8 to 20 carbon atoms, and wherein the isoalkane mixture is obtained by a method in which a) a C 4- hydrocarbon mixture is provided, which comprises less than 3% by weight of isobutene, b) the C 4- hydrocarbon mixture is subjected to an oligomerization over a transition-metal-containing catalyst, and c) the oligomerization product obtained in step b) is completely hydrogenated; wherein the oligomerization product obtained in step b) and/or the hydrogenation product obtained in step c) is subjected to a separation, wherein a fraction enriched in C 16 -oligomers is obtained.
