| 41 | Removal of halogen from polyhalogenated compounds by electrolysis | US725103 | 1985-04-19 | US4585533A | 1986-04-29 | Jacob J. Habeeb |
| A method for electrochemically removing halogen from a halogenated compound utilizing an electrically conducting liquid medium in an electrolytic cell is disclosed. Halogen is extracted and reacted with a metal present in the sacrificial anode to form a relatively insoluble metal halide salt. The invention is of particular utility in removing halogen from aromatic and aliphatic compounds. | ||||||
| 42 | ULTRA-LOW POWER DIGITAL CHEMICAL ANALYZERS | US15376562 | 2016-12-12 | US20180231514A1 | 2018-08-16 | Hanseup Kim; Carlos Mastrangelo |
| A zero-power digital chemical analyzer can include a chemically-selective percolation switch. The chemically selected percolation switch can include a positive electrode and a negative electrode separated from the positive electrode by a gap. A binding agent can be located at binding sites in the gap. The binding agent can be selective for binding to a target chemical compound. The binding sites can be distributed in the gap so that target chemical molecules binding to the binding sites can form an electrically conductive pathway via a natural percolation phenomenon between the electrodes when the ambient concentration of the target chemical compound reaches a threshold concentration. | ||||||
| 43 | Process for the destruction of sulfur and nitrogen mustards and their homologous/analogous at ambient conditions | US12078001 | 2008-03-26 | US08618346B2 | 2013-12-31 | Inas Muen Al Nashef; Saeed M. Al Zahrani |
| The subject invention provides a potentially economically viable process for the destruction of small to large quantities of sulfur and nitrogen mustards and lewisite, their homologous/analogues, and similar chemical warfare agents at ambient conditions without producing any toxic by-products. The process uses the superoxide ion that is either electrochemically generated by the reduction of oxygen in ionic liquids or chemically by dissolving Group 1 (alkali metals) or Group 2 (alkaline earth metals) superoxides, e.g. potassium superoxide, in ionic liquids. | ||||||

| 50 | Method of decomposing CMPO | US35064 | 1998-03-05 | US5965003A | 1999-10-12 | Masaki Ozawa; Yasumasa Tanaka; Yoshihiro Hoshino; Hiroyuki Tanuma; Chisako Kawakami; Takamichi Kishi |
| CMPO is safely, reliably and rapidly decomposed under mild conditions. A CMPO-containing substance is emulsified in an electrolyte comprising an oxidation promoter (silver ion) by an emulsifier in an emulsifying tank, this electrolyte comprising the CMPO-containing substance is supplied to an anode chamber, and an electrolytic oxidation reaction is performed by passing an electric current. By emulsifying the CMPO-containing substance, the surface area of CMPO in contact with electrolyte is increased, and electrolytic decomposition is thereby promoted. As sufficient CMPO decomposition is not obtained by passing the emulsion only once through an electrolysis tank 1, a batch oxidation method is employed wherein an anolyte is recirculated by a recirculating pump 3a through the anode chamber, a constant temperature bath 7a and an emulsifying tank 6, so that electrolysis is performed with the CMPO-containing substance permanently emulsified in the electrolyte. To maintain a catholyte in a cathode chamber at the same temperature as the anolyte, the catholyte is recirculated by a recirculating pump 3b between the cathode chamber and a constant temperature bath 7b. The current supplied to an anode 4 and cathode 5 in the electrolysis tank 1 is controlled by a rectifier 8. | ||||||

| The invention comprises a method and apparatus using high cerium concentration in the anolyte of an electrochemical cell (100) to oxidize a treatment mixture of an organic phase in an aqueous solution. Acidic anolyte comprising cerium in an original oxidant state is emulsified together with the organic material in an ultrasonic mixer (114). This reaction mixture is passed to a reactor tank (700) wherein the organic material reacts with the anolyte destroying the organic material and reducing the oxidant in the anolyte. A portion of the anolyte goes to the electrochemical cell (100) and is oxidized and regenerated before it passes back into the anolyte tank (112). The reaction vessel (700) provides an advantage of independent reaction temperature control and electrochemical cell temperature control. | ||||||
