ABC-Salt WP 3.2 Data underlying the publication: Hydrolysis of eutectic compositions in the ZnCl2:KCl:NaCl ternary system and effect of adding ZnO

The objective of this work is to investigate the properties of the eutectic mixtures of ZnCl2:KCl:NaCl that are of importance for thermochemical conversion of biomass. Four compositions of ZnCl2:KCl:NaCl are investigated, including Salt #1: 60: 20: 20, Salt #2: 59.5: 21.9: 18.6, Salt #3: 52.9: 33.7: 13.4 and Salt #4: 44.3: 41.9:13.8 in mole fraction. Salt #4 is found to exhibit the best properties, with low melting point, the highest thermal stability and the lowest hydrolysis rate. Salt #1 had the highest hydrolysis rate. However, addition of ZnO showed a marked, limiting effect on the hydrolysis

本研究旨在探究氯化锌（ZnCl₂）:氯化钾（KCl）:氯化钠（NaCl）共晶混合物（eutectic mixtures）的相关特性，该类混合物对于生物质热化学转化具有重要应用价值。本研究共考察了四种该类共晶混合物的配比，分别为试样1：60:20:20、试样2：59.5:21.9:18.6、试样3：52.9:33.7:13.4以及试样4：44.3:41.9:13.8，均以摩尔分数计。实验结果表明，试样4的综合性能最优，其具备较低的熔点、最高的热稳定性以及最低的水解速率。试样1的水解速率最高。不过，添加氧化锌（ZnO）可对水解过程产生显著的抑制作用。
