Abstract

Polyethylene and

-olefins have been major products in petrochemical industry

in which their catalysts have been recognized as key points within the industrial processes. The iron

the most abundant element of transition metals in the Earth's crust

has attracted considerable attention from researchers due to its minimal price

low toxicity and favourable biocompatibility. Surprisingly

iron complexes as catalysts show excellent performance in the catalytic systems such as oligomerization or/and polymerization of ethylene. Relied on their electronic and steric influences of substituents within ligand compounds used

iron complexes not only show different catalytic activities of ethylene reactivity but also produce different products from oligomers with low molecular weights to polyethylenes with various molecular weights. In another word

the microstructures of the resulting products can be controlled by finely tuning the electronic effects and steric hindrance of the ligands used to achieve a variety of products with highly linear and molecular weight differences from

-olefins and highly linear polyethylene. In addition

most polyethylenes obtained have been approved with narrow distributions

especially for some types of polyethylene wax. In this review

the progress of iron complex catalysts for ethylene oligomerization or/and polymerization is reviewed

indicating the effects of ligand frameworks and their modifications through using different substituents as well as the differences in the catalytic activities and the microstructural properties of the obtained products. It would be temporarily short of its interest and attractiveness in academy

however

its industrial application would drive funds and keep its further investigations. To enhance the living life of any science

the 2-‍(imino)phenanthroline-iron catalysts were used in ethylene oligomerization to successfully produce

-olefins in a 50 kt/y process by Sinopec Maoming Branch in September 2021

which promoted Sinopec to construct a further developed process with 200 kt/y in Tianjin at November of 2021. It is the first iron catalyst being used in the petrochemical industry

moreover

it is the first process for a full range of

-olefins achieved in Asian area until now. Therefore

the iron complex catalysts are highly promising and useful in advanced products including

-olefins

polyethylene wax and linear polyethylenes.
