摘要： Bromine containing compounds, such as calcium bromide, sodium bromide and the like, are prepared in high purity and more quickly with less waste by using a process with two bromination stages and often a third step wherein the crude product mixture can be adjusted to meet specific product requirements. In the first bromination stage, the majority, but not all, of a substrate is brominated using a reductive bromination reaction, the remaining unreacted substrate is converted to product in the second stage through another a reductive bromination reaction, although the specific reagents may be different, wherein the addition of bromine and a reducing agent are carefully monitored.

摘要： Pure halogen salts of alkaline and/or alkaline earth metals or a mixture thereof are prepared by (I) hydrolytically heating a suspension of 1 part by weight of a halogenic, organic waste material in a comminuted state in 1-10 parts by weight of an aqueous medium in the presence of a base to a temperature ranging from 200-300° C. at a pressure sufficient to maintain the water in a liquid state for a period of time sufficient to convert substantially all the organically bound halogen present to inorganic halides, and (II) separating the hydrolysate obtained in step (I) into a solid hydrolysate fraction and a liquid hydrolysate fraction, (III) neutralizing the liquid hydrolysate with hydrohalogenic acid, (IV) adding a flocculent to the neutralized hydrolysate; (V) separating the material from step (IV) into a solid containing fraction and an aqueous solution; and (VI) nanofiltering the aqueous solution to obtain a retentate and a permeate, wherein the permeate is further treated to obtain the pure salts.

摘要： A starting material for producing optical fibers contains metal halides. The refractive index of the optical fiber formed from the starting material is predeterminable by adjusting a partial pressure ratio of a halogen-containing gas mixture. The starting material is produced by mixing halogenated gases into a gas mixture with the desired partial pressure ratio, causing a chemical reaction at a first temperature of the gas mixture with at least metal to form a reaction product, the first temperature being higher than the melting temperature of the reaction product and cooling the reaction product to a second temperature that is below the melting temperature.
