CHROMIUM AND NICKEL CATALYST FOR OLIGOMERIZATION REACTION AND PROCESS FOR OBTAINING ALPHA-OLEFIN USING THE CATALYST |
| 摘要 |
<P>PROBLEM TO BE SOLVED: To provide synthesis of precatalysts for the selective production of alpha-olefins and chromium and nickel oligomerization catalysts with the use of such precatalysts in ethylene oligomerization reactions. <P>SOLUTION: The invention refers to the preparation and use of coordination compounds containing polydentate ligands comprising Group 6 and 10 transition metal compounds in the periodic table, in particular chromium (III) and nickel (II). Such catalytic precursors present high catalytic activity and selectivity for the production of alpha-olefins. <P>COPYRIGHT: (C)2013,JPO&INPIT |
