The present invention provides a method of producing oligomers of olefins, comprising reacting olefins with a catalyst under oligomerization conditions. The catalyst can be the product of the combination of a chromium compound and a pyridyl ether compound. In particular embodiments, the catalyst compound can be used to trimerize or tetramerize ethylene to 1-hexene, 1-octene, or mixtures of 1-hexene and 1-octene.

The present invention provides a method of producing oligomers of olefins, comprising reacting olefins with a chromium based catalyst under oligomerization conditions. The catalyst can be the product of the combination of a chromium compound and a pyridyl thioether compound. In particular embodiments, the catalyst compound can be used to trimerize or tetramerize ethylene to 1-hexene, 1-octene, or mixtures of 1-hexene and 1-octene.

Described is a parallel batch reactor for effecting chemical reactions. The parallel batch reactor includes a plurality of reactor vessels for receiving components of a reaction, an inlet port for receiving pressurized fluid, and a plurality of valves configured to transfer fluid from the inlet port to the reactor vessels and fluidically isolate one or more of the reactor vessels from at least one of the other reactor vessels. The reactor further includes a pressure monitoring system comprising an array of pressure sensors configured to sense pressure in the reactor vessels. Each of the pressure sensors is aligned with one of the plurality of reactor vessels and located external to the reactor vessels and fluid passageways in fluid communication with the reactor vessels.

Parallel batch reactor with pressure monitoring

In one embodiment, a parallel batch reactor generally includes a plurality of reactor vessels and a plurality of valves configured to allow flow into the reactor vessels when a gas is supplied to the reactor at a pressure higher than a pressure within the reactor vessels and restrict flow from the reactor vessels. A method includes inserting chemical components into the reactor vessels, supplying a first gas to the reactor vessels to pressurize the reactor vessels, stopping supply of the first gas, and supplying a second gas to the reactor at a lower pressure than a pressure within the reactor vessels. The second gas passes through the valves and into the reactor vessels when the pressure within the reactor vessels drops below the pressure of the second gas.

Methods of oligomerizing olefins

An apparatus and method for injection of one or more chemical components into a reaction chamber are disclosed. The apparatus includes a reaction chamber for receiving one or more libraries in a fixed position relative to the chamber and configured to form a sealed enclosure. An injection manifold is located within the reaction chamber and selectively movable relative to the libraries. The injection manifold is configured for receiving at least one fluid transfer line coupled to an external source for injection of one or more chemical components into the reaction chamber.

New ligands, compositions, metal-ligand complexes and arrays with pyridyl-amine ligands are disclosed that catalyze the polymerization of monomers into polymers. Certain of these catalysts with hafnium metal centers have high performance characteristics, including higher comonomer incorporation into ethylene/olefin copolymers, where such olefins are for example, 1-octene, isobutylene or styrene. Certain of the catalysts are particularly effective at polymerizing propylene to high molecular weight isotactic polypropylene in a solution process at a variety of polymerization conditions.

Substituted pyridyl amine catalysts and processes for polymerizing crystalline polymers

A method is disclosed for screening potential catalysts for polymerization performance. The method includes the steps of reacting a potential catalyst with at least a first monomer under polymerization conditions, determining the polymerization performance of the catalyst with the at least first monomer, and using the determination as a predictor for the polymerization performance of the catalyst for at least a second monomer, wherein the first and second monomers are different from each other and the first monomer is an olefin other than ethylene. The method provides a useful, concrete and tangible result that has particular value for identifying appropriate catalysts for olefin polymerization and copolymerization.
