In the DES literature, ternarysystems are often simplified as pseudo-binaries by fixing the molarratio of two components and varying only the third along a fixed-compositionline (isopleth). Although this reduces the experimental effort, itrestricts <em>liquidus</em> mapping to a single compositionalpathway and may fail to identify the global ideal eutectic. In contrast,our implementation solves the classical ideal <em>liquidus</em> equations for all components, assuming Raoult-law ideality and pure,mutually immiscible solid phases. Using pure-component melting temperaturesand molar fusion enthalpies, the method enables multidimensional <em>liquidus</em>-surface mapping. The root-finding implementationwas verified against analytical symmetric-mixture solutions, independent80-digit calculations, a MATLAB implementation, permutation tests,3,521 stress-test systems, and published benchmarks. All stress-testsystems converged, and published ideal eutectic temperatures werereproduced within 0.7 K. Application to literature-reported binaryand ternary mixtures further showed that comparison with the globalideal eutectic combines an apparent local thermal deviation with anonnegative ideal-composition penalty. The framework therefore providesa transparent and extensible ideal-equilibrium baseline for multicomponenteutectic screening.</p>","PeriodicalId":42,"journal":{"name":"Journal of Chemical & Engineering Data","volume":"71 10","pages":"4156–4167"},"PeriodicalIF":2.4,"publicationDate":"2026-10-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149124645","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
