Oligomerization catalyst
-
, (2008/06/13)
An oligomerization catalyst for olefins is obtainable from a) a chromium compound CrX3 and the at least equimolar amount, based on the chromium compound CrX3, of a ligand L or from an existing chromium complex CrX3L, in which the groups X are, independently of one another, abstractable counterions and L is a 1,3,5-triazacyclohexane of the formula I ?where the groups R1 to R9 are, independently of one another: hydrogen or organosilicon or substituted or unsubstituted carboorganic groups having from 1 to 30 carbon atoms, where two geminal or vicinal radicals R1 to R9 may also be joined to form a five—or six-membered ring, andb) at least one activating additive and also a process for preparing oligomers of olefins using these catalysts, the oligomers thus obtainable, and the oxo alcohols obtainable from these oligomers.

The Cr-catalyzed trimerization of 1-decene and 1-dodecene is a highly selective method to synthesize C30 and C36 olefins. After hydrogenation, these products display very attractive viscosity indices (VI's). Due to the high trimer se
