improved process for dimerizing lower α-olefins using a novel nickel-containing Ziegler catalyst system comprising
(A) an organic acid salt or complex of nickel,
(B) a trialkylaluminum,
(C) a trivalent phosphorus compound of the formula:
wherein R', R2, R3 are alkyl, cycloalkyl, aryl or aralkyl,
(D) a fluorinated isopropanol of the formula:
wherein m and n are in 4 ≦ m+n ≦ 6, and optionally
(E) a catalyst co-activator: halogenated compounds of the formulae:
and
wherein X is halogen, R4, R5, R6 are alkyl, and n is 1 to 3, and further optionally,
(F) a compound selected from aliphatic alcohol and aliphatic carboxylic acid or ester thereof,
which gives the dimers with high selectivity of isomers and uniformity of catalyst without corrosion of apparatus.
