The catalyst can be the product of the combination of a chromium compound and a pyridyl amine or a heteroaryl-amine compound. In particular embodiments, the catalyst compound can be used ... 11/02/06 - 20060247482 - Method and system to recycle non-isomerized monomer in an ionic liquid catalyzed chemical reaction In an embodiment, a method to produce an oligomer using a recycle stream that contains a substantially non-isomerized monomer. The monomer is contacted with an ionic liquid catalyst to produce the oligomer. The monomer includes at least one alpha olefin. Along with the substantially non-isomerized monomer, a dimer can also ... 08/03/06 - 20060173227 - Process for the production of highly reactive polyisobutenes The present invention relates to a process for the production of highly reactive polyisobutenes with a content of terminal vinylidene groupings of greater than 80 mol % and an average molecular weight of 500 to 10,000 Dalton by cationic polymerization of isobutene or of isobutene and monomers copolymerizable with isobutene ... 12/22/05 - 20050283036 - Process for obtaining a butadiene homopolymer in the presence of monoolefin(s) with 4 carbon atoms an alkylating agent of the formula AlR3 or HAlR2, where R is an alkyl group, and an alkylaluminum halide halogen donor. ... 11/17/05 - 20050256356 - Process for the gas-phase (co-)polymerisation of olefins in a fluidised bed reactor The present invention relates to a process for the gas-phase (co-)polymerisation of olefins in a fluidised bed reactor using a Ziegler-Natta type catalyst characterised in that the polymerisation is performed in the presence of a monohalogenated hydrocarbon compound. ... 09/01/05 - 20050192471 - Catalytic composition and its application to olefin oligomerization An improved catalytic composition for oligomerization, in particular dimerization, of monoolefins comprises the product resulting from bringing the following three constituents into contact in any order: a) at least one divalent nickel compound; b) at least one hydrocarbylaluminium dihalide, optionally enriched with an aluminium trihalide; and c) at least one ... 09/01/05 - 20050192470 - Process for oligomerization of ethylene to linear alpha-olefins A process for preparing α-olefins from ethylene wherein the α-olefins are substantially free of olefins having greater than 12 carbon atoms comprises contacting ethylene under oligomerization conditions with a 2,6-bis(phenylimino) pyridyl metal halide catalyst in which the metal is Fe, Ni, Co or Pd. ... 08/25/05 - 20050187419 - Catalyst for trimerization of ethylene and process for trimerizing ethylene using the catalyst A catalyst used for trimerization of ethylene into 1-hexene is descrobed, which comprises (i) a specific organometallic complex having a neutral multidentate ligand having a tripod structure, (ii) an alkylaluminoxane, and an optional ingredient selected from: (iii) a halogenated inorganic compound, (iv) a specific alkyl group-containing compound, (v) a combination ... 08/25/05 - 20050187418 - Olefin oligomerization Provided is a method of oligomerizing alpha olefins. In an embodiment, an oligomerization catalyst system is contacted in at least one continuous reactor with a feed comprising olefins; an effluent comprising product olefins having at least four carbon atoms is withdrawn from the reactor; the oligomerization catalyst system comprises iron ... 06/02/05 - 20050119514 - Oligomerization of olefins comprising at least three carbon atoms A description is given of a process for the oligomerization of α-olefins having at least 3 carbon atoms, in which the olefin is brought into contact with a catalyst system obtainable from a chromium source, a 1,3,5-trialkyl-1,3,5-triazacyclohexane, where the alkyl radical has no α, β or γ branching, and at ... ### FreshPatents.com Support |
