    • The process includes reacting a reaction mixture comprising magnesium ethoxide (Mg(OEt)2), triethylaluminum (TEAl), and 2-ethylhexanol (2-EHOH) to form magnesium 2-ethyl hexyl alkoxide (Mg(2-EHO)2) and contacting Mg(2-EHO)2 in hexane with a first agent to form a reaction product “A.” The process further includes contacting the reaction product “A” with a second agent to form a reaction product “B”, wherein the second agent includes a transition metal and a halogen. The process further includes contacting the reaction product “B” with a third agent to form a reaction product “C”, wherein the third agent includes a first metal halide. In addition, the process includes contacting the reaction product “C” with a fourth agent to form a reaction product “D”, wherein the fourth agent includes a second metal halide. The process also includes contacting the reaction product “D” with a fifth agent to form a Ziegler-Natta catalyst, wherein the fifth agent includes an organoaluminum compound.
    • 该方法包括使包含乙醇镁(Mg(OEt)2),三乙基铝(TEAl)和2-乙基己醇(2-EHOH)的反应混合物反应以形成2-乙基己基醇镁(Mg(2-EHO)2)和 使Mg(2-EHO)2在己烷中与第一试剂接触以形成反应产物“A”。该方法进一步包括使反应产物“A”与第二试剂接触以形成反应产物“B”,其中第二 剂包括过渡金属和卤素。 该方法还包括使反应产物“B”与第三试剂接触以形成反应产物“C”,其中第三试剂包括第一金属卤化物。 此外,该方法包括使反应产物“C”与第四试剂接触以形成反应产物“D”,其中第四试剂包括第二金属卤化物。 该方法还包括使反应产物“D”与第五试剂接触以形成齐格勒 - 纳塔催化剂,其中第五试剂包括有机铝化合物。
