2. Description of the Prior Art 1-olefins having 4, 6 and 8 carbon atoms are important compounds as raw materials for copolymerization with ethylene for producing linear low-density polyethylene. Heretofore, these low-molecular-weight 1-olefins have been obtained mainly from the decomposition products of naphtha. Of these, butene-1, which is a 1-olefin having 4 carbon atoms, is supplied in large quantities and inexpensively from naphtha decomposition products.

On the other hand, 1-olefins having 6 and 8 carbon atoms are always in short supply due to the limited amount in naphtha decomposition products, and 1-olefins having 6 and 8 carbon atoms are in short supply. The development of a selective manufacturing method has been desired. As such a production method, various methods using a catalyst have been proposed so far. For example, a method using a catalyst composed of a zirconium compound and an aluminum compound is known as a method capable of suppressing by-product of a polymer.

It has been difficult to selectively increase 1-olefins having 6 and 8 carbon atoms. For example, as a zirconium compound, Z
r (O-n-C 3 H 7) 4 or Zr [N (n-C 4 H 9 ) 2 ]
In the method using No. 4 (Japanese Patent Publication No. 50-30042), the selectivity of 1-olefins having 6 and 8 carbon atoms is generally low, while when the selectivity is high, the production of polymer increases. was there. In addition, in a method using a zirconium compound containing a phenoxy group having an electron-withdrawing substituent and an organoaluminum compound as a catalyst (Japanese Patent Publication No. 2-13649), the production of a polymer is small and a direct polymer having 4 to 8 carbon atoms is used. Although chain α-olefins are selectively produced, in this method, the selectivity of the olefin having 4 carbon atoms is remarkably high, and the desired carbon atoms of 6 and 8 are obtained.
Has a problem that the selectivity of 1-olefin is low.
