METALATED LIGAND, CATALYST COMPOSITION, AND USE THEREOF IN THE OLIGOMERIZATION OF ETHYLENE |
摘要 |
A process for oligomerization of ethylene, comprising subjecting a catalyst composition to a gas phase of ethylene and conducting an oligomerization, wherein the catalyst composition comprises (a) a chromium compound, (b) a metalated ligand, and (c) an activator or cocatalyst; and catalyst composition as well as a metalated ligand. |

1. A process for oligomerization of ethylene, comprising contacting a catalyst composition with a gas phase of ethylene under conditions effective to oligomerize the ethylene, wherein the catalyst composition comprises
(a) a chromium compound, (b) a metalated PNPNH compound, wherein the PNPNH compound is of the formula
R1R2P—N(R3)—P(R4)—N(R5)—Hwherein R1, R2, R3, R4 and R5 are independently selected from halogen, amino, trimethylsilyl, C1-C10-alkyl, substituted C1-C10-alkyl, C6-C20-aryl and substituted C6-C20-aryl, or any cyclic derivative wherein at least one of the P or N atoms of the PNPN—H structure is a member of a ring system, the ring system being formed from one or more constituent compounds of the PNPNH-structure by substitution, and
(c) an activator or cocatalyst. |
