Title:
RARE EARTH METAL CATALYST COMPOSITION, PREPARATION METHOD THEREFOR, AND USE THEREOF
Document Type and Number:
WIPO Patent Application WO/2024/066457
Kind Code:
A1
Abstract:
Provided is a rare earth metal catalyst composition, which comprises the following raw materials: a main catalyst, a first alkyl metal reagent, and a polyene accelerator, wherein the structural general formula of the main catalyst is: LLnL1L2, wherein the L structure is: (II); the general formula of the first alkyl metal reagent is MR11 n. The rare earth metal catalyst composition has long catalytic activity duration and high catalytic efficiency, and the solubility of a catalyst after activation in alkane is good.
