PHOSPHACYCLE COMPOUND AND PROCESS FOR PRODUCTION THEREOF

The invention relates to oligomerization of olefins, such as ethylene, to higher olefins, such as a mixture of 1-hexene and 1-octene, using a catalyst system that comprises a) a source of chromium b) one or more activators and c) a phosphacycle-containing ligating compound. Additionally, the invention relates to a phosphacycle-containing ligating compound and a process for making said compound.

TETRAMERISATION OF ETHYLENE

A process for the tetramerisation of ethylene includes contacting ethylene with a catalyst under ethylene oligomerisation conditions. The catalyst comprises a source of chromium, a ligating compound, and an activator. The ligating compound includes a phosphine that forms part of a cyclic structure.

TETRAMERISATION OF ETHYLENE

A process for the tetramerisation of ethylene under solution phase conditions is carried out in the presence of an activated catalyst at a temperature above 80° C and up to a temperature of about 115°C. The activated catalyst is provided by combining a source of chromium, a diphosphine ligating compound and optionally a catalyst activator or combination of catalyst activators. The process forms at least 30% 1-octene and a polyethylene co-product that, together with any other reaction products, remains substantially dissolved in the liquid phase. The polyethylene co-product has a weight average molecular weight (Mw) of less than 200 000 g/mol, a number average molecular weight (Mn) of less than 3 000 g/mol, and a melt flow index of more than 20 g/10 minutes.

TETRAMERISATION OF ETHYLENE

A process for the tetramerisation of ethylene under solution phase conditions is carried out in the presence of an activated catalyst at a temperature above 80°C and up to a temperature of about 130°C. The activated catalyst is provided by combining a source of chromium, a ligating compound, which ligating compound includes at least one fluorine substituted hydrocarbyl group, organoheteryl group, or heterohydrocarbyl group, and optionally a catalyst activator or combination of catalyst activators.

BULK ETHYLENE OLIGOMERIZATION USING A LOW CONCENTRATION OF CHROMIUM CATALYST AND THREE-PART ACTIVATOR

This invention enables the "bulk" oligomerization of ethylene (i.e. the oligomerization of ethylene in the presence of the oligomer product) using a catalyst system comprising 1) a very low concentration of a chromium catalyst and 2) a three part activato

ETHYLENE OLIGOMERIZATION PROCESS WITH ALIIMINOXANE/ORGANOBORON AS ACTIVATORS USING A HALOGENATED AROMATIC SOLVENT

This invention provides a two stage process for the oligomerization of ethylene in the presence of a chromium catalyst having a bridging diphosphine ligand. The process mitigates problems which may be experienced during the unsteady state conditions that

HEAT MANAGEMENT IN ETHYLENE OLIGOMERIZATION

The oligomerization of ethylene using a chromium catalyst having a heteroatomic ligand is used to provide oligomerization products that are selective towards hexene and/or octene. However, such processes also typically produce some polymer as an undesired

OLIGOMENZATION OF ALPHA OLEFINS

The oligomerization of ethylene using a chromium catalyst having a phosphorus-nitrogen-phosphorus ("P-N-P") ligand is typically activated with an aluminoxane. The addition of an alkyl zinc, particularly diethyl zinc, has been fund to improve the productiv

AMINO PHOSPHINE

A new P-N-P ligand having the formula (ortho-F-C6H4)2P-N-C(CH3)2 in which each phosphorus atom is bonded to two ortho-fluorine- substituted phenyl groups. In combination with i) a source of chromium a
