1343638 Recovering silver values AMERICAN METAL CLIMAX Inc 19 April 1971 [14 April 1970] 23829/71 Heading ClA [Also in Division C7] Silver is recovered from electrolytic copper refinery slimes by slurrying the slimes in a HCl solution, and reacting with gaseous Cl 2 to solubilize most of the...
When a part is immersed in a solution containing hexavalent chromium, zinc is oxidized by reacting with Cr6+, which turns to Cr3+. Zinc oxide dissolves to the acidic solution and reacts with trivalent chromium to form zinc chromium oxide compounds, which will precipitate on the surface, ...
Above 0.6 M, the shear strength decreased with the increase in N2H4 concentration. Though the metallic Cu particle powders were obtained by the same washing and drying processes as those of the CuO particles, some N2H4 unreacting with Cu ions might have not been completely removed from the ...

adding deionized water or organic solvent B to 4/5-24/25 of the reaction kettle in volume, reacting at 20-200 DEG C for 0.5-50 hours, taking out the copper substrate after the reaction finishes, washing with ethanol, and drying to obtain the nano Cu2-xSe array on the copper substrate...
Isophorone diisocyanate (IPDI, 5 mL) was then dripped in this system with intense agitation. After reacting at 52 °C for 7 h, 0.1 L DMF was added. The intermediate GO-IPDI was obtained through filtering with a 0.2 μm PTFE microporous membrane. GO-IPDI (0.1 g) was re-dispersed in ...
k) reacting hydrogen chloride gas from steps g) and j), the remaining portion of the residual solution after step i) and the recovered ferrous chloride from step j) with oxygen under pressure to thereby regenerate a predetermined amount of ferric chloride containing lixiviant and to simultaneously...
The process comprises reacting a compound having the formula ##STR6## with a compound having the formula H2 N--O--Ra, or a salt or ester thereof, in the presence of a copper salt. DETAILED DESCRIPTION OF THE INVENTION The use of a copper salt as a mediator for the reaction of a ...
A process for the preparation of naphthalene-1,4-dicarboxylic acid, which comprises reacting 1,4-dihalogenonaphthalene with at least 2 moles of copper-I cyanide per mole of dihalogenonaphthalene in a polar, aprotic solvent and subjecting the copper salt
