  • CATALYST COMPOSITION FOR OLIGOMERIZATION OF ETHYLENE AND PROCESSES OF OLIGOMERIZATION
    Publication number: 20130018214
    Abstract: The present invention provides a catalyst composition for the ethylene oligomerization, which comprises 2-imino-1,10-phenanthroline coordinated iron (II), cobalt (II) or nickel (II) chloride as main catalyst and triethylaluminum as cocatalyst. The present invention also provides a process for oligomerization of ethylene is provided, wherein a catalyst composition comprising 2-imino-1,10-phenanthroline coordinated iron (II), cobalt (II) or nickel (II) chloride as main catalyst and triethylaluminum as cocatalyst is used, and the molar ratio of aluminum in the cocatalyst to central metal in the main catalyst ranges from 30 to less than 200. According to the present invention, another process for oligomerization of ethylene is also provided, wherein a catalyst composition comprising 2-imino-1,10-phenanthroline coordinated iron (II), cobalt (II) or nickel (II) chloride as main catalyst and triethylaluminum as cocatalyst is used, and the temperature of ethylene oligomerization ranges from ?10 to 19° C.
