Abstract

Data are obtained concerning the extraction of hydroiodic, hydrobromic, and hydrochloric acids from solutions using a mixture of tributyl phosphate and molecular iodine. A significant increase in the extraction of these acids by tributyl phosphate in the presence of iodine has been revealed. According to extractability, these acids can be arranged in the series of HCl < HBr < HI. The separation factors for these hydrohalic acids are very high, which can provide their efficient separation in a countercurrent process. The possibility has been established for the extraction of bromine from calcium chloride brines with obtaining potassium bromide via washing bromide extracts from metals by acids and reextracting bromide ion by alkaline reagents such as potassium hydroxide or potash solutions.

评估磷酸三丁酯和分子碘混合物从天然存在的氯化钙卤水中提取获得溴化钾的可能性

摘要

获得了有关使用磷酸三丁酯和分子碘的混合物从溶液中萃取氢碘酸，氢溴酸和盐酸的数据。已经发现在碘存在下通过磷酸三丁酯萃取这些酸的显着增加。根据可萃取性，这些酸可以按照HCl <HBr <HI的顺序排列。这些氢卤酸的分离因子非常高，可以在逆流过程中提供有效的分离。已经确定了从氯化钙盐水中提取溴的可能性，方法是通过用酸洗涤金属中的溴化物提取物并用碱性试剂（例如氢氧化钾或钾盐溶液）再提取溴离子来获得溴化钾。
