    • The present invention is directed to a method of dimerizing lower olefins which comprises dimerizing a lower olefins in the presence of a catalyst, wherein the catalyst used comprises a nickel compound, an organic aluminum compound, and a phosphite compound having the general formula (I): ##STR1## wherein R.sup.1, R.sup.2, R.sup.3, and R.sup.4 are phenyl groups optionally substituted by substituents and may be different from each other, at least two of R.sup.1, R.sup.2, R.sup.3, and R.sup.4 have a hydrocarbon group as a substituent in the ortho position; A is a divalent aliphatic, alicyclic or aromatic hydrocarbon group which optionally has a substituent; and n is 0 or 1. The present invention is also directed a method of producing alcohol by means of hydroformylating and hydrogenating the newly formed olefins obtained through the said dimerization method of the lower olefins. In the dimerization method of the lower olefins according to the present invention, it is possible to produce in an economic manner olefinic mixtures which are high in activity and low in degree of branching. In addition, the alcohols produced with the said olefins show totally superior performance as the raw material for plasticizers, which are thus valuable in industrial applications.
