In the quaternary NH<sub>4</sub>Cl + MgCl<sub>2</sub> + SrCl<sub>2</sub> + H<sub>2</sub>O system, two non-variant points and four crystallization regions were determined. These regions include the crystallization of NH<sub>4</sub>Cl, MgCl<sub>2</sub>·6H<sub>2</sub>O, and SrCl<sub>2</sub>·6H<sub>2</sub>O, together with the double salt, which was identified as NH<sub>4</sub>Cl·MgCl<sub>2</sub>·6H<sub>2</sub>O. In contrast, the system (LiCl + MgCl<sub>2</sub> + SrCl<sub>2</sub> + H<sub>2</sub>O) exhibits three non-variant points and five crystallization regions: LiCl·H<sub>2</sub>O, MgCl<sub>2</sub>·6H<sub>2</sub>O, SrCl<sub>2</sub>·6H<sub>2</sub>O, SrCl<sub>2</sub>·2H<sub>2</sub>O, and double salt LiCl·MgCl<sub>2</sub>·7H<sub>2</sub>O. The results of experiments on these quaternary systems are importance for the separation and purification of minerals found in the oilfield brine in the Nanyishan region, Qaidam Basin.</p>","PeriodicalId":762,"journal":{"name":"Russian Journal of Inorganic Chemistry","volume":"71 9","pages":"1322 - 1330"},"PeriodicalIF":1.5,"publicationDate":"2026-08-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149023172","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
