    摘要: This invention is directed to a novel method for purifying calomel (Hg.sub.2 Cl.sub.2). More particularly, this invention pertains to a novel process for treating impure calomel (Hg.sub.2 Cl.sub.2) to produce a highly purified calomel product that passes American Chemical Society requirements for calomel assay and mercuric chloride contamination. A process for treating impure calomel to produce purified calomel comprising: (a) incorporating impure calomel into an aqueous slurry; (b) oxidizing the aqueous slurry with an oxidizing agent to form soluble mercuric chloride; (c) filtering the aqueous slurry containing soluble mercuric chloride into liquid and solid components; (d) heating the liquid component to greater than 70.degree. C; (e) treating the liquid component with a reducing agent to precipitate purified calomel; and (f) separating the precipitated purified calomel from the filtrate.

    摘要: Apparatus for producing purified metal halides, such as sodium iodide and mixtures of sodium iodide and mixtures of sodium iodide with scandium iodide, of accurately controlled particle size, particularly useful as a vaporizable fill for high pressure discharge devices. The apparatus may include means for evaporating volatiles from the solid impure metal halide, melting the impure halide, passing hydrogen, hydrogen halide, hydrogen and halogen, or mixtures thereof through the halide, and then passing the molten halide through a vibrating discharge conduit or nozzle into an inert quenching atmosphere to form the particles of purified halide.

    摘要: REMOVAL OF MERCURY FROM GASES, IN PARTICULAR GASES FROM COMBUSTION OR ROASTING, IS ACHIEVED BY WASHING THE GASES WITH SULPHURIC ACID OF AT LEAST 5% HAVING A TEMPERATURE OF 60 TO 180* C. THE WASHING ACID AND THE GASES CONTAIN CHLORIDE OR CHLORINE COMPOUNDS OR BOTH CHLORINE AND CHLORINE COMPOUNDS IN SUCH AN AMOUNT THAT THE ATOMIC RATIO C1/HG IS AT LEAST 1:1. PRACTICALLY ALL MERCURY AND OTHER MERCURY COMPOUNDS ARE CONVERTED TO MERCURY CHLORIDES WHICH ARE SEPARATED BY CONDENSATION IN A SUCCEEDING COOLING OF THE GAS.

    摘要: Compositions are described including free-flowing particles of controlled size of purified metal halides such as sodium iodide and mixtures of sodium iodide with scandium iodide. These ultrapure metal halide particles are particularly useful as a vaporizable fill disposed within an arc tube of a high pressure electric discharge device. The preparation and identification of the coordination entity Na ScI 4 (III) is also described. The process for producing purified metal halides of accurately controlled particle size includes evaporating volatiles from the solid impure metal halide, melting the impure halide, passing hydrogen, hydrogen halide, hydrogen and halogen, or mixtures thereof through the halide, and then passing the molten halide through a vibrating discharge conduit or nozzle into an inert quenching atmosphere to form the particles of purified halide.
