Method of Inhibiting Reactor Fouling and Oligomerisation of Olefin Using the Same

Provided are a fouling inhibitor and a method of oligomerizing an olefin using the same. More particularly, in the method of oligomerizing an olefin, it is possible to minimize a total amount of polymers produced during a reaction and basically inhibit fouling of the polymers produced during the reaction onto an inner wall of a reactor by injecting a predetermined fouling inhibitor.

Oligomerization of Ethylene

Provided is a method for oligomerization of ethylene, and more particularly, a method for producing 1-hexene and 1-octene at a high selectivity under an ethylene atmosphere by inducing a remarkably improved catalytic activity while effectively reducing a production amount of polyethylene by introducing the oligomerization catalyst and a cocatalyst mixture containing at least two aluminums together and adjusting the kind of oligomerization catalyst and injection conditions thereof.

Methoxycarbonylation with formic acid as CO source

A catalytic process for the methoxycarbonylation of olefins where formic acid is the CO source. The process includes the steps of forming a reaction mixture where methanol and formic acid are added at a volume ratio in the range from 1.55:0.45 to 1.1:09. The methanol-formic acid ratio enhances both the rate of conversion and methyl ester yield ether produced. The catalysts used is a palladium/benzene-base diphosphine ligand complex.
