| 摘要 |
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 R2AlX. RAlX2, R3Al2X3, R3Al and R2Zn where R is C1-C20 alkyl and X is Cl or Br. ZrCl4 adducts with organic acetates are the preferred embodiments. |
