Patent number: 7745652Abstract: Integrated processes of preparing industrial chemicals starting from seed oil feedstock compositions containing one or more unsaturated fatty acids or unsaturated fatty acid esters, which are essentially free of metathesis catalyst poisons, particularly hydroperoxides; metathesis of the feedstock composition with a lower olefin, such as ethylene, to form a reduced chain olefin, preferably, a reduced chain ?-olefin, and a reduced chain unsaturated acid or ester, preferably, a reduced chain ?,?-unsaturated acid or ester. The reduced chain unsaturated acid or ester may be (trans)esterified to form a polyester polyolefin, which may be epoxidized to form a polyester polyepoxide. The reduced chain unsaturated acid or ester may be hydroformylated with reduction to produce an ?,?-hydroxy acid or ?,?-hydroxy ester, which may be (trans)esterified with a polyol to form an ?,?-polyester polyol.Type: GrantFiled: December 5, 2008Date of Patent: June 29, 2010Assignee: Dow Global Technologies Inc.Inventors: Zenon Lysenko, Bob R.

Patent number: 5320816Abstract: The simultaneous abatement of NO and SO.sub.2 in flue gas is provided by an absorption process and apparatus utilizing an absorbent composition comprising an aqueous solution of chelates and sulfite salts. Metal chelates oxidized to an inactive state are electrochemically reduced. In the electrochemical cell, nickel or stainless steel anode materials are stable and may be used in the place of platinum coated anode materials when the anolyte pH is maintained greater than 12. At these conditions, the anode is corrosion resistant with a long operating time between replacement. Ultrafiltration or Donnan dialysis may be used to separate the chelate sorbents from the waste salts to reduce the loss of expensive chelate sorbents. Alternatively, an anionic exchange membrane can be used to electrodialytically separate waste sulfur/nitrogen salts from the absorbent solution.Type: GrantFiled: October 21, 1992Date of Patent: June 14, 1994Assignee: The Dow Chemical CompanyInventors: Susan S. Tsai, Stephen A. Bedell, Larry H. Kirby, Aubrey J. Rhymes, Jr., Richard D. Varjian
