Abstract

Selective oligomerization of ethylene has attracted significant attention in recent years. However, studies on the effects of co-catalysts and solvents remain limited. In this work, a chromium complex bearing a two-carbon-bridged diphosphine (PCCP) ligand, known for its high activity and selectivity in ethylene tri-/tetramerization, was investigated. Triisobutylaluminum (TIBAL) and dry methylaluminoxane (DMAO) were employed as co-catalysts, and the influence of solvent conditions on catalytic activity and linear alpha olefin selectivity was examined. The synthesized catalyst was characterized by elemental analysis, and product distributions were determined using gas chromatography-mass spectrometry (GC-MS). This study provides fundamental insights and reference data on the effects of co-catalysts and solvents in PCCP-Cr catalyzed selective ethylene oligomerization.


에틸렌의 선택적 올리고머화 촉매 기술은 현재 활발히 연구되고 있지만 상대적으로 조촉매 및 용매 효과를 다룬 연구는 부족하다. 본 연구에서는 높은 선택성과 활성이 보고된 두 개의 탄소로 연결된 다이포스핀 리간드(PCCP)를 갖는 Cr 복합체의 에틸렌 삼량체화 및 사량체화를 수행하였다. Triisobutylaluminum(TIBAL)과 dry methylaluminoxane (DMAO)를 조촉매로 사용하였으며 조성비, 온도, 용매에 따른 활성과 선택성의 변화를 체계적으로 분석하였다. 촉매 합성은 원소 분석을 통해 확인하였고 생성된 선형 알파 올레핀의 분포는 기체 크로마토그래피 질량 분석법(GC-MS)으로 분석하였다. 본 연구는 PCCP-Cr 복합체가 촉매로 작용하는 선택적 에틸렌 삼량체화 및 사량체화에서 조촉매 및 용매 효과에 대한 기초적 이해와 참고 데이터를 제공한다.
