The relative effectiveness of CuO and Cu2O were compared as catalysts for the methylchlorosilane (MCS) reaction. MCS reactions catalyzed by CuO had higher rates (0.15 g/g Si-h) than MCS reactions catalyzed by Cu2O (0.08) AND higher selectivities (4–5 points in % Di higherfor CuO). A synthetic method was found for making 17O-labeledCu2O based on reaction of CuCl with excess NaCl and >2equivalents...
A safe analytical technique for determining the concentration amount of dibutyl and monobutyl phosphate degradation products in the TBP-dodecane solvent used in solvent extraction processes. This method of chemical analysis eliminates the use of diazomethane, which is toxic and explosive, thereby providing a safer laboratory technique for routine analyses required to monitor production solvent extraction...
