Patent number: 4375453Abstract: 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.

Patent number: 4265871Abstract: Sulfuric acid contaminated with boron and fluoride values such as the waste acid of a boron trifluoride process is purified by contacting the contaminated acid with an inert gas to desorb boron trifluoride, and the inert gas is stripped by contacting with an absorbing liquid including concentrated sulfuric acid. Fluosulfonic acid is added to contaminated sulfuric acid at levels approximately three times the molar values of boric acid contaminant as an agent to spring non-volatile boron values. The absorption of boron trifluoride into the absorbing sulfuric acid is improved when it contains boric acid. Preferably the contaminated sulfuric acid to be purified is one portion of the waste liquid and the absorbing liquid is another portion of the waste liquid of a boron trifluoride manufacturing process. Boric acid is added to the absorbing liquid, then boron trifluoride is stripped from the inert gas and absorbed into the absorbing liquid.Type: GrantFiled: May 7, 1979Date of Patent: May 5, 1981Assignee: Allied Chemical CorporationInventors: Charles J.

Patent number: 4227027Abstract: 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.Type: GrantFiled: November 23, 1979Date of Patent: October 7, 1980Assignee: Allied Chemical CorporationInventors: Robert E. Booth, Francis E. Evans, Richard E. Eibeck, Martin A. Robinson
