| 20100116683 | Low Energy 4-Cell Electrochemical System with Carbon Dioxide Gas - A low-voltage, low-energy electrochemical system and method of producing hydroxide ions and/or bicarbonate ions and/or carbonate ions utilizing significantly less than the typical 3V used across the conventional anode and cathode to produce the ions; consequently, carbon dioxide emissions attributable to the present system and method are significantly reduced. | 05-13-2010 |
| 20100282614 | Process for producing sodium carbonate and/or sodium bicarbonate from an ore mineral comprising sodium bicarbonate - In a process to produce sodium carbonate and/or sodium bicarbonate from an ore mineral comprising sodium bicarbonate, a production solution comprising sodium carbonate is introduced into less basic compartments of an electrodialyser comprising alternating less basic and more basic adjacent compartments separated from each other by cationic membranes, the more basic compartments being delimited by anionic faces of bipolar membranes on one side and by the cationic membranes on the other side; a solution comprising sodium hydroxide is produced into the more basic compartments by combination of sodium ions flux crossing the cationic membrane and hydroxyl ions flux crossing the anionic face of the bipolar membranes, and is then extracted from the electrodialyser to be used as a reaction solution; the reaction solution is put into contact with the mineral ore to form a solution comprising sodium carbonate; and the solution comprising sodium carbonate is divided into a part used as the production solution and a remaining part used as a produced solution. | 11-11-2010 |
| 20110147229 | PROCESS FOR PRODUCTION OF DIARYL CARBONATE - The invention relates to a process for production of diaryl carbonate combined with the electrolysis of the resultant alkali metal chloride-containing process wastewater. The process according to the invention makes possible, inter alia, improved utilization in electrolysis of the alkali metal chloride-containing solution obtained in the production of diaryl carbonate. | 06-23-2011 |
| 20120132537 | HETEROCYCLE CATALYZED CARBONYLATION AND HYDROFORMYLATION WITH CARBON DIOXIDE - Methods and systems for heterocycle catalyzed carbonylation and hydroformylation with carbon dioxide are disclosed. A method may include, but is not limited to, steps (A) to (D). Step (A) may introduce water to a first compartment of an electrochemical cell. The first compartment may include an anode. Step (B) may introduce carbon dioxide to a second compartment of the electrochemical cell. The second compartment may include a solution of an electrolyte, a heterocyclic catalyst, and a cathode. Step (C) may introduce a second reactant to the second compartment of the electrochemical cell. Step (D) may apply an electrical potential between the anode and the cathode in the electrochemical cell sufficient to induce liquid phase carbonylation or hydroformylation to form a product mixture. | 05-31-2012 |
| 20120152757 | PROCESS FOR THE ELECTROCHEMICAL FLUORINATION OF ORGANIC COMPOUNDS - The present invention relates to a process for the electrochemical fluorination of an organic compound, wherein a reaction solution comprising the organic compound and a fluorinating agent is subjected to electric current in an electrochemical fluorination cell. | 06-21-2012 |
| 20120186988 | METHOD FOR PRODUCING A RADIOACTIVELY MARKED CARBOXYLATE - A method produces a radioactively marked carboxylate, at least one precursor molecule of the carboxylate being prepared in a solvent including a conductive salt. Radioactively marked carbon dioxide is fed into the solvent. The precursor molecule is electrochemically reacted with the radioactively marked carbon dioxide to form the radioactively marked carboxylate. The radioactively marked carbon dioxide is completely dissolved in the solvent when the precursor molecule is reacted. The radioactively marked carbon dioxide is used for electrochemically synthesizing a radioactively marked carboxylate, the carbon dioxide being completely dissolved in a solvent during synthesis. A microstructure is used for electrochemically synthesizing the radioactively marked carboxylate, radioactively marked carbon dioxide being reacted. | 07-26-2012 |
