NEW NICKEL COMPOUNDS, THEIR MANUFACTURE AND USE AS CATALYSTS FOR OLIGOMERIZING OLEFINS

摘要

Nickel compounds of the formula (R1COO) (R2COO) Ni, where R1is hydrocarbyl of at least 5 carbon atoms and R2 is haloalkyl of 1-3 carbon atoms, are manufactured from the corresponding acids R1COOH and R2COOH or salts thereof. The resultant nickel compounds are soluble in hydrocarbons and can be used in admixture with organoaluminum compounds as constituents of catalytic compositions; olefins can be oligomerized, for example, dimerized and trimerized, therewith.
