    摘要： Gd.sub.2 O.sub.3 and Ga.sub.2 O.sub.3 are currently used for the fabrication of Gd.sub.3 Ga.sub.5 O.sub.12 (GGG) wafers which are employed as substrates for bubble domain memory devices. In the processing, in the order of 25% of the starting material ends up as process "saw kerf" contaminated with variable amounts of iron, nickel, magnesium, aluminum, zirconium, iridium and silicon. A process is described whereby the "saw kerf" can be reprocessed in sufficient purity to be re-used in the process, thereby improving the economics of production of GGG wafers significantly. Gadolinium and gallium oxides are recovered and separated from transition metal impurities introduced during fabrication of GGG wafers. The process "saw kerf" produced from slicing the crystal boule is dissolved in HCl, treated with H.sub.2 SO.sub.4, and the resulting sulfates separated. Metathesis with (NH.sub.4).sub.2 C.sub.2 O.sub.4 results in conversion of the sulfates to the ammonium oxalates which were calcined at 850.degree. C. to form Ga.sub.2 O.sub.3 and Gd.sub.2 O.sub.3 of purity >99.99%. The process can be extended to include purification and re-use of by-products generated in other grinding and polishing operations which may result in the recycling of the order of 80% of the generated by-products.

    摘要： A process for the conversion of boron trifluoride dimethyl ether complex to boron trifluoride dialkyl ether complex substantially free of dimethyl ether impurities, which comprises reacting the boron trifluoride-dimethyl ether complex, in the liquid phase, in the presence of dialkyl ether wherein at least one of the alkyl groups contains at least two carbon atoms, in a restricted vapor equilibration region, while simultaneously sweeping the said vapor equilibration region with a substantially inert gas, and heating to distill off the dimethyl ether. High purity of the boron trifluoride dialkyl ether complex is attained with this method, with only minimal traces of the boron trifluoride dimethyl ether complex, dimethyl ether remaining. The preferred product is boron trifluoride diethyl ether.

    摘要： A method for treating process waste consisting of uranium hexafluoride, UF.sub.6, molybdenum hexafluoride, MoF.sub.6 and molybdenum oxytetrafluoride, MoOF.sub.4 is provided wherein the foregoing mixture is hydrolyzed in an aqueous solution of ammonium carbonate and ammonium hydroxide. The resulting mother liquor is digested at 60.degree.-80.degree. C. to drive off carbon dioxide and convert the ammonium uranyl carbonate, (NH.sub.4).sub.4 UO.sub.2 (CO.sub.3).sub.3 to ammonium diuranate, (NH.sub.4).sub.2 U.sub.2 O.sub.7. The pH is maintained above 9 to prevent premature precipitation of the molybdenum values as molybdic acid or uranyl molybdate.The ammonium diuranate which forms as a yellow solid is filtered, slurried in aqueous ammonium hydroxide, filtered and dried. The yield is quantitative. Pyrolysis results in conversion of the diuranate salt to uranium oxide, U.sub.3 O.sub.8, of suitable purity to be recycled in the uranium hexafluoride production process. The combined filtrates which contain the molybdenum values and ammonium fluoride by-product are diluted, and stirred, with 95% ethanol to precipitate white, crystalline, ammonium molybdate, (NH.sub.4).sub.2 MoO.sub.4. The ammonium fluoride remains soluble. The ammonium molybdate is filtered, dried and calcined at 600.degree. C. for 2 hours to yield molybdenum trioxide, MoO.sub.3 in >90% yield and essentially free of uranium contamination. Fluoride contamination in either of the reprocessed materials is minimal.

    摘要： When saturated with boron trifluoride, certain polyhydric alcohols form adducts which catalyze hydrocarbon alkyl transfer reactions for which boron trifluoride is catalytic. The adduct is recovered from the reaction mixture and recycled, greatly reducing boron and fluoride values in the product and in any effluent. Examples include propylation of toluene in the presence of a recycled adduct of boron trifluoride with mannitol or sorbitol, and the oligomerization of decene by a recycled adduct of boron trifluoride with mannitol or butanediol. Some of the catalysts become viscous on cooling and are thus more easily separated from the reaction products which remain in a separate liquid phase.
