  • Process for oligomerizing C.sub.3 and higher olefins using zirconium adducts as catalysts (CS-467)
    Patent number: 5449850
    Abstract: C.sub.3 and higher olefins are oligomerized using a two component catalyst system comprising (a) a soluble adduct of zirconium tetrahalide, the halogen being Br or Cl, with an organic compound selected from the group of esters, ketones, ethers, amines, nitriles, anhydrides, acid chlorides, amides or aldehydes, the organic compound having up to about 30 carbon atoms and (b) an alkyl metal selected from the group R.sub.2 AlX, RAlX.sub.2, R.sub.3 Al.sub.2 X.sub.3, R.sub.3 Al and R.sub.2 Zn where R is C.sub.1 -C.sub.20 alkyl and X is Cl or Br. ZrCl.sub.4 adducts with organic acetates are the preferred embodiments. Dimers, trimers and tetramers are selectively prepared in the process.
    Type: Grant
    Filed: March 12, 1991
    Date of Patent: September 12, 1995
    Assignee: Exxon Chemical Patents Inc.

  • Process for preparing linear alpha-olefins using zirconium adducts as catalysts
    Patent number: 4966874
    Abstract: Linear alpha-olefins are prepared by the oligomerization of ethylene using a two component catalyst system comprising (a) a soluble adduct of zirconium tetrahalide, the halogen being Br or Cl, with an organic compound selected from the group of esters, ketones, ethers, amines, nitriles, anhydrides, acid chlorides, amides or aldehydes, the organic compound having up to about 30 carbon atoms and (b) an alkyl metal selected from the group R.sub.2 AlX. RAlX.sub.2, R.sub.3 Al.sub.2 X.sub.3, R.sub.3 Al and R.sub.2 Zn where R is C.sub.1 -C.sub.20 alkyl and X is Cl or Br. ZrCl.sub.4 adducts with organic acetates are the preferred embodiments.
