DIMERIZATION OF LOWER .ALPHA.-OLEFINS

摘要

The present invention is directed to a process for preparing a dimer of a lower .alpha.-olefin in the presence of Catalyst (A) containing a nickel compound, a trialkylaluminum, a halogenated phenol, a phosphorous compound and a sulfur compound, Catalyst (B) containing a nickel compound, a trialkylaluminum, a fluorinated isopropyl alcohol, a phosphorous compound, a sulfonic acid and water, or Catalyst (C) containing a nickel compound, a trialkylaluminum, a halogenated phenol, a phosphorous compound, a sulfonic acid and water, by which method, the dimer of the lower .alpha.-olefin is prepared in a high yield and with high selectivity.
