The new complex Fe(N,N,O)Cl_2(N,N,O=6-[1-{(2-methy)imino)ethyl]-2-acetylpyridine)was prepared and evaluated as precatalyt in the oligomerization of ethylene,using methylaluminoxane (MAO)as cocatalyst and 1,1,2,2-tetrachloroethane as accelerant.The catalytic activities and selectivities of the system in ethylene oligomerization were studied under different reaction temperatures,n(Al)/n(Fe)and reaction pressure.The optimum reaction conditions were as follows:18 μmol/L of catalyst,40℃,3.0 MPa,n(Al)/n(Fe)=1200,reaction time 30 min.0.4 mL accelerant.The activity reached 3.8×10~6 g/mol·h and the selectivity of buterte-1 was less than 10%;where as the selectivities of hexene-1 and octene-1 were more than 22%and 2.3%,respectively.
