摘要： A dual temperature isotope exchange process of the type having a first stage comprising a hot and a cold tower with liquid and gas passing in countercurrent exchange relation therein, the gas being recycled from the top of the cold tower to the bottom of the hot tower via a humidifier section through which a liquid stream also passes, a dehumidifier between hot and cold towers through which both gas and liquid streams pass, the improvement comprising the feeding of the inlet feed liquid at a raised temperature to the top of the humidifier section that is, to a point between the liquid outlet of the hot tower and the liquid input to the humidifier and the recycling of a portion of the liquid leaving the hot tower to the top of the cold tower preferably via a cooling device.

摘要： The present invention relates to a process for cultivating larger unstressed single-domain crystals containing niobium and an alkali metal, preferably lithium. The process is conducted by the Zochralski technique for cultivating crystals from a melt in an oxidizing moist atmosphere by means of resistance heating, which maintains an electric short circuit between crystal seed and the melt.

摘要： ALKALINE SOLUTIONS CONTAINING TELLURIUM AND SELENIUM BUT SUBSTANTIALLY FREE OF HEAVY METAL IONS, ARE TREATED WITH STRONG OXIDANTS TO PRECIPITATE HIGH PURITY ALKALI METAL ORTHOTELLURATE AT TEMPERATURES BELOW THE ATMOSPHERIC BOILING POINT. THE ORTHOTELLURATE MAY BE FURTHER TREATED BY CONTACTING IT WITH A REDUCTANT TO CONVERT TELLURIUM FROM THE +6 VALENCE STATE TO ITS +4 VALENCE STATE. THE PH IS THEN ADJUSTED TO THE ACID RANGE TO PRECIPITATE TELLURIUM DIOXIDE OF EXCEPTIONAL PURITY. HIGH PURITY METALLIC TELLURIUM MAY BE PRODUCED FROM THE TELLURIUM DIOXIDE IN ACCORDANCE WITH WELL-KNOWN TECHNIQUES.

摘要： The present invention is a trona concentrate and a process for floating gangue material from trona ore that comprises forming an emulsion, conditioning the trona ore at a high solids content in a saturated trona suspension, and then floating and removing the gangue material. The process for separating trona from gangue materials in trona ore can include emulsifying an oil in an aqueous solution to form an oil-in-water emulsion. A saturated trona suspension having a high solids content can also be formed having trona of a desired particle size. The undissolved trona in the saturated suspension can be conditioned by mixing the saturated suspension and the oil-in-water emulsion to form a conditioning solid suspension of trona and gangue material. A gas can be injected through the conditioning solid suspension to float the gangue material. Thus, the floated gangue material can be readily separated from the trona to form a purified trona concentrate without requirements of additional heat or other expensive processing steps.

摘要： The invention relates to a chiral solid catalyst containing a BEA topology zeolite and a metal-binap complex and to a process for the production of substantially enantiomerically pure products from prochiral starting material with the catalyst. The BEA topology zeolite may be a BETA zeolite, an acid BEA topology zeolite, an acid NU-2 zeolite, or an ammonium BEA topology zeolite. The metal in the metal-binap complex is ruthenium, iridium, nickel, or rhodium. The zeolite is normally impregnated with a solution of the metal-binap complex. The method is applicable to asymmetric hydrogenation of beta functionalized ketones, betaketoesters, functionalized olefins, and .alpha., .beta.-unsaturated functionalized olefins.

摘要： A process for producing stable, particular perhydrates of sodium carbonate and phosphates comprising contacting the precursor of the perhydrate with concentrated hydrogen peroxide solution in such quantity as to develop the desired active oxygen content in the particles. The perhydrate is recovered by drying. Stabilizers may be present in the precursor or may be added prior to, with, or after hydrogen peroxide addition. The perhydrate may be agglomerated to meet end-use particle size requirements by contacting the particles with water, optionally containing an agglomerating agent or stabilizer. Reaction and perhydrate uniformity are achieved by balancing water content, reaction conditions, residence time under reaction conditions, and stabilizer content.
