Synthesis and characterization of oligomer from 1‐decene catalyzed by AlCl 3 /TiCl 4 /SiO 2 /Et 2 AlCl

Oligomer of 1‐decene was synthesized with Ziegler‐Natta catalyst consisting of TiCl 4 , AlCl 3 , Et 2 AlCl, and SiO 2 used as support. The effects of temperature, time, ratio of Al/Ti, and concentration of Ti on oligomerization behaviors were investigated. The results showed that the catalyst system was desirable for oligomerization of 1‐decene with good catalytic activity, 153.4 kg oligomer/mol Ti h, under typical conditions. The oligomer obtained was characterized with GC–MS, GC, and 13 C NMR methods. The results indicated that the oligomer was of a mixture consisting of di‐, tri‐, tetra‐, and pentamer. The 13 C NMR data also implied that chain propagation of this oligomer involved primarily head‐to‐tail 1, 2‐insertions, as well as head‐to‐head and tail‐to‐tail 2, 1‐insertions. © 2006 Wiley Periodicals, Inc.
