    Abstract: Procedure for manufacturing oligomers by continuous oligomerization of butenes characterized in that a) an initial stream is used which contains 1 butene and 2 butene at a total concentration of 10 to 70 wt% and 10 to 60 wt% of iso butane (called initial stream 1 hereafter) b) said initial stream 1 is converted until more than 60 wt% of the 1 butene contained in initial stream 1 but less than 50 wt% of the 2 butene contained in initial stream 1 are converted into oligomers c) the oligomers obtained in b) are separated and optionally fed to further processing and the remaining stream is fed to a distillation processing step d) iso butane is separated by distillation from the remaining steam e) the iso butane depleted stream (called initial stream 2 hereafter) obtained after the distillation processing step d) is converted into oligomers.

    Abstract: A process for preparing oligomers by continuous oligomerization of butenes is described, wherein a) a feed stream (1) comprising I-butene and 2-butene in a total concentration of from 10 to 70% by weight and from 10 to 60% by weight of isobutane is reacted until more than 60% by weight of the I-butene comprised in the feed stream (1 ) but less than 50% by weight of the 2-butene comprised in feed stream (1) have been converted into oligomers. b) The oligomers obtained in a) are separated off and optionally passed to a further work-up and the remaining residual stream is fed to work-up by distillation. c) Isobutane is separated off by distillation from the residual stream, and d) the isobutane-depleted stream obtained after the work-up by distillation c) is reacted to form oligomers.
