摘要:
A catalyst composition is manufactured by admixing a hydrocarbyl aluminum halide of a nickel compound of the formula (R.sub.1 COO)(R.sub.2 COO)Ni, where R.sub.1 is hydrocarbyl with at least 5 carbon atoms and R.sub.2 is haloalkyl of 1-3 carbon atoms. Olefins such as ethylene, propylene and butenes can be oligomerized, for example, dimerized and trimerized, with the above catalyst composition.

摘要:
Nickel compounds of the formula (R.sub.1 COO) (R.sub.2 COO) Ni, where R.sub.1 is hydrocarbyl of at least 5 carbon atoms and R.sub.2 is haloalkyl of 1-3 carbon atoms, are manufactured from the corresponding acids R.sub.1 COOH and R.sub.2 COOH or salts thereof. The resultant nickel compounds are soluble in hydrocarbons and can be used in admixture with organoaluminum compounds as constituents of catalytic compositions; olefins can be oligomerized, for example, dimerized and trimerized, therewith.
摘要:
In order to carry out selective dimerization of propylene principally into branched dimers, a catalytic composition resulting from at least partly dissolving a nickel compound mixed or complexed with a tertiary phosphine carrying a functional group is used in a medium resulting from mixing at least one quaternary ammonium halide and/or at least one quaternary phosphonium halide, at least one aluminum halide and optionally at least one organometallic aluminum compound.
摘要:
A catalytic composition comprising at least one nickel compound mixed or complexed with at least one tertiary phosphine or a phosphite carrying a functional group, at least partly dissolved in a non-aqueous medium with an ionic nature resulting from bringing at least one aluminum halide into contact with at least one quaternary ammonium halide and/or at least one quaternary phosphonium halide, is useful for dimerizing, co-dimerizing and oligomerizing olefins. Functional groups include, but are not limited to, an amine, a cyclic amine, a nitrogen-containing heterocycle, an ester, an acid, an alcohol, a quaternary ammonium, a quaternary phosphonium, a sulfonium, a sulfonate or a phosphonate group.
摘要:
Process for oligomerizing ethylene into light alpha olefins, mainly 1-butene, 1-hexene, 1-octene and 1-decene, in which the ethylene is contacted with a catalyst obtained by mixing a zirconium compound with an organic compound chosen from within the class of acetals and ketals and with a chlorine or bromine-containing compound of aluminum hydrocarbyl.
摘要:
A non-aqueous liquid composition with an ionic character resulting from the contacting of at least one alkylaluminum dihalide with at least one quaternary ammonium halide and/or at least one quaternary phosphonium halide, said composition being liquid below 80.degree. C., for example, between -70.degree. and +40.degree. C., is useful as a solvent of catalysts for the dimerization, codimerization and oligomerization of olefins.
摘要:
Process for the homologation of an alcohol wherein a ketal of the alcohol is reacted with hydrogen and carbon monoxide in the presence of a cobalt carbonyl complex and the resultant product is hydrolyzed to yield the aldehyde with one more carbon atom.
摘要:
New catalytic composition of improved activity in the process of polymerizing cycloolefins, comprising a carbonyl compound or a carbonyl-metal-carbenic compound of molybdenum or tungsten and titanium tetrachloride, said composition being preferably subjected to an irradiation with rays of a wave length from 180 to 700 nanometers during or before use.
