Abstract: Supported catalysts contain a transition metal compound impregnated on or bound to a solid support, and the transition metal is iron, cobalt, or manganese. The solid support is an inorganic solid oxide or a chemically-treated solid oxide. The transition metal compound is prepared by reacting a transition metal halide containing a ligand with an alkylating agent in a suitable reaction medium at a temperature of −70 to 15° C., prior to impregnating onto the solid support.

Abstract: This disclosure provides for catalyst systems and processes for forming an α,β-unsaturated carboxylic acid or a salt thereof. In an aspect, the catalyst system can comprise: a transition metal precursor comprising a Group 8-11 transition metal and at least one first ligand; optionally, at least one second ligand; an olefin; carbon dioxide (CO2); a diluent; and an oxoacid anion-substituted polyaromatic resin comprising a sulfonated polyaromatic resin, a phosphonated polyaromatic resin, a sulfinated polyaromatic resin, a thiosulfonated, or a thiosulfinated polyaromatic resin, and further comprising associated metal cations. Methods of regenerating the polyaromatic resin with associated metal cations are described.

Abstract: A method comprising a) contacting a solvent, a carboxylic acid, and a peroxide-containing compound to form an acidic mixture wherein a weight ratio of solvent to carboxylic acid in the acidic mixture is from about 1:1 to about 100:1; b) contacting a titanium-containing compound and the acidic mixture to form a solubilized titanium mixture wherein an equivalent molar ratio of titanium-containing compound to carboxylic acid in the solubilized titanium mixture is from about 1:1 to about 1:4 and an equivalent molar ratio of titanium-containing compound to peroxide-containing compound in the solubilized titanium mixture is from about 1:1 to about 1:20; and c) contacting a chromium-silica support comprising from about 0.1 wt. % to about 20 wt. % water and the solubilized titanium mixture to form an addition product and drying the addition product by heating to a temperature in a range of from about 50° C. to about 150° C. and maintaining the temperature in the range of from about 50° C. to about 150° C. for a time period of from about 30 minutes to about 6 hours to form a pre-catalyst.

Abstract: Methods for preparing supported chromium catalysts containing a chromium (III) compound and an activator-support are disclosed. These supported chromium catalysts can be used in catalyst compositions for the polymerization of olefins to produce polymers having low levels of long chain branching, and with greater sensitivity to the presence of hydrogen during polymerization.

Abstract: This disclosure provides for routes of synthesis of acrylic acid and other α,β-unsaturated carboxylic acids and their salts, including catalytic methods. For example, there is provided a process for producing an α,β-unsaturated carboxylic acid or a salt thereof, the process comprising: (1) contacting in any order, a group 8-11 transition metal precursor, an olefin, carbon dioxide, a diluent, and a polyaromatic resin with associated metal cations to provide a reaction mixture; and (2) applying conditions to the reaction mixture suitable to produce the α,β-unsaturated carboxylic acid or a salt thereof. Methods of regenerating the polyaromatic resin with associated metal cations are described.
