摘要： A method is disclosed for production of a sulfate-containing salt and anhydrous gaseous HCl from a metal chloride (MClx) and oleum. MClx and oleum are mixed together with a water-containing liquid, forming gaseous HCl and a solution of a sulfate-containing salt or double salt. The salt is precipitated from the solution, and in a preferred embodiment, the supernatant liquid from the precipitation is recycled to the reaction mixture as the water-containing liquid in subsequent reaction cycles. In a preferred embodiment, HCl discharged from the reaction mixture is scrubbed to remove dust, water vapor and traces of H2SO4, yielding anhydrous HCl of >90% purity. The exothermicity of the reaction between the water-containing liquid and the oleum is sufficient that, unlike methods known in the prior art, the process proceeds quickly and efficiently without any necessity for additional heating of the reaction mixture. This method provides high-purity, low-chlorine sulfates, including the novel potassium sulfate double salts K3(NH4)(SO4)2, 3K2SO4*MgSO4 and 3K2SO4*CanMg2-nSO4.
摘要翻译：公开了一种从金属氯化物（MClx）和发烟硫酸生产含硫酸盐和无水气态HCl的方法。将MClx和发烟硫酸与含水液体混合在一起，形成气态HCl和含硫酸盐或复盐的溶液。盐从溶液中沉淀出来，并且在一个优选的实施方案中，来自沉淀的上清液在随后的反应循环中作为含水液体循环到反应混合物中。在一个优选实施方案中，从反应混合物排出的HCl被洗涤以除去灰尘，水蒸气和痕量的H 2 SO 4，产生纯度> 90％的无水HCl。含水液体与发烟硫酸之间反应的放热性足以使得与现有技术中已知的方法不同，该方法快速有效地进行而无需额外加热反应混合物。该方法提供了高纯度，低氯硫酸盐，包括新型硫酸钾复盐K3（NH4）（SO4）2，3K2SO4 * MgSO4和3K2SO4 * CanMg2-nSO4。
