Abstract: A gaseous mixture of SF.sub.6, a nitriding gas component and an oxidizer gas component is disclosed as an effective SiO.sub.2 etchant having enhanced selectively for use in either the plasma or reactive ion etch process. By adding an oxidizing gas to the SF.sub.6 nitriding gas plasma etchant, the selectively for SiO.sub.2 over silicon or polysilicon is marked improved. The optional addition of an inert diluent gas did not substantially change these results.

Abstract: A dinitrile is hydrogenated to an omega-aminonitrile with hydrogen with a supported highly dispersed rhodium catalyst and only ammonia present. The catalyst is prepared by hydrolyzing a rhodium(III) halide or nitrate with strong aqueous base at elevated temperatures, drying the supported rhodium hydroxide at elevated temperatures and intimately contacting with hydrogen the dried product with hydrogen at 260.degree.-360.degree. C. High conversions, selectivity to aminonitrile and long catalyst service times and catalyst recyclability are achieved in the absence of an aprotic solvent.

Abstract: 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.

Abstract: A novel process is disclosed for producing fluorinated pyromellitate surfactants. The process comprises two primary steps. The first step involves reacting pyromellitic dianhydride with fluorinated alcohol at a mole ratio of about two moles of fluorinated alcohol per mole of pyromellitic dianhydride, thereby producing a pyromellitate having two fluorinated esters moieties and two carboxylic acid moieties. Thereafter, the fluorinated pyromellitate with carboxylic acid moieties is reacted with an oxirane compound in the presence of trimellitic anhydride to produce fluorinated pyromellitate mixtures having a reduced percentage of fluorine.
