Abstract: A method for producing copper oxide. In the method, a copper bearing material, aqueous ammonia, and a sufficient amount of an ammonium salt to double the rate of production of copper oxide in the absence of the salt are placed in a single vessel. The vessel is closed, and oxygen is fed into the vessel. The mixture is stirred and heated to a temperature of between approximately 70.degree. and 130.degree. C. to dissolve the copper bearing material into aqueous ammoniacal copper ion. The aqueous ammoniacal copper ion is reacted with the oxygen in the vessel to form solid copper oxide particles, which are then recovered.

Abstract: A process for the preparation of a dispersed Group VI-B metal sulfide hydrocarbon oil hydroprocessing catalyst comprising reacting aqueous ammonia and a Group VI-B metal compound, such as molybdenum oxide or tungsten oxide, to form water soluble compounds such as aqueous ammonium molybdates or tungstates. The aqueous ammonium molybdates or tungstates are sulfided at a relatively low temperature with hydrogen sulfide without feed oil, and wherein the mole ratio of the sulfiding agent to metal salts is greater than 2, to produce molybdenum or tungsten sulfide catalysts of high hydroprocessing activity. The catalyst slurry and feed oil can then be passed to a hydroprocessing reactor or can be further sulfided in additional steps of increasing temperature.

Abstract: A process for the preparation of a dispersed Group VIB metal sulfide hydrocarbon oil hydroprocessing catalyst comprising reacting aqueous ammonia and a Group VIB metal compound, such as molybdenum oxide or tungsten oxide, to form water soluble compounds such as aqueous ammonium molybdates or tungstates. The aqueous ammonium molybdates or tungstates are sulfided at a relatively low temperature with hydrogen sulfide without feed oil. The slurry stream is then passed through a separator and ammonia is flashed and separated from the system, leaving a separator residue slurry. The separator residue slurry is then mixed with feed oil, hydrogen and hydrogen sulfide and sulfided at a relatively high temperature to produce a dispersed molybdenum sulfide or tungsten sulfide catalyst of high hydroprocessing activity. The catalyst slurry and feed oil can then be passed to a hydroprocessing reactor.

Abstract: A wood preservative composition comprises a wood preservative such as a chromated copper arsenate-oil emulsion or an ammoniacal copper arsenate emulsion having about 0.1 to 15 percent chromated copper arsenate, ammoniacal copper arsenate, or ammoniacal copper zinc arsenate, about 1 to 20 percent oil and about 0.3 to 2.5 percent (based on total final emulsion) surfactant material. The first surfactant preferably has a hydrophilic lipophilic balance of about 7 to 9.5 and a second surfactant has a hydrophilic lipophilic balance of about 15 to 20. It is preferred that the first surfactant have an ethoxyl mole ratio less than about 5 and that the second surfactant have a mole ratio greater than about 15. The surfactant material may be composed of a first surfactant having an average mole ratio of about 1 to 5 and a second surfactant having an average mole ratio of about 20 to 100. The composition is storage stable for extended periods and provides a number of beneficial properties for wood products.
