Abstract: The invention provides compounds that inhibit epoxide hydrolase in therapeutic applications for treating hypertension. A preferred class of compounds for practicing the invention have the structure shown by Formula 1 wherein Z is oxygen or sulfur, W is carbon phosphorous or sulfur, X and Y is each independently nitrogen, oxygen, or sulfur, and X can further be carbon, at least one of R1-R4 is hydrogen, R2 is hydrogen when X is nitrogen but is not present when X is sulfur or oxygen, R4 is hydrogen when Y is nitrogen but is not present when Y is sulfur or oxygen, R1 and R3 is each independently C1-C20 substituted or unsubstituted alkyl, cycloalkyl, aryl, acyl, or heterocyclic.

Abstract: In a metal-winning method, copper ore or copper-ore concentrates is effectively hydraulically leached in a chloride leach liquor and the resultant leached liquor is diaphragm-electrolyzed. A chloride electrolyte containing Br? ions and the leached metals is subjected to a diaphragm-electrolysis in an electrolytic cell comprising an anode compartment (4) and a cathode compartment (3). A portion of the electrolyte in the anode compartment (4) is withdrawn from below an anode (2) of the anode compartment (4) and is returned to the leaching step so as to increase the oxidation potential of the chloride leach liquor.

Abstract: A method of producing high purity electrolytic copper through halide-bath electrowinning is provided. The method includes the steps of: growing copper in dendritic form to be deposited on a cathode; and recovering growth ends of 3.0 mm or shorter from the dendrites.

Abstract: In a method for recovering antimony from the electrolyte of copper electro-refining process, the antimony is adsorbed on the chelating resin and is then eluted by acid. The eluate is then neutralized to recover antimony. In a conventional method, a large amount of acid and alkali is used. In the inventive eluting method, the antimony concentration in the acidic eluting solution is adjusted to 4 g/L or more in the first step and 3 g/L or less in the second step.

Abstract: Disclosed in the present invention is a process for selectively separating and recovering cobalt by liquid-liquid extraction from an aqueous solution containing cobalt such as those obtained by leaching a cobalt-containing ore with an acid by utilizing an organic solvent containing an alkyl ester of alkylphosphonic acid as the extractant.
