To the Editor: This journal has recently published a study on solubility of molybdenum trioxide, MoO3, in aqueous solutions (water, sodium chloride, or triflate) at 250°, 300°, and 350°C, and vapor-saturated water pressure (Shang et al., 2020). The authors have found that the MoO3 solubility is minimal in water and starts increasing at the molality of NaCl above 0.01 m. Surprisingly, the authors made no comparison of their solubility data with relevant results from the literature, although such a comparison could be made. Indeed, high-temperature solubility of MoO3 in water was reported by...

MoO 3（s）在高达350°C的温度下的热液中的溶解度和形态的实验研究—讨论

致编辑：该杂志最近发表了一项研究，研究三氧化钼MoO3在250°C，300°C和350°C的水溶液（水，氯化钠或三氟甲磺酸盐）中的溶解度以及蒸汽饱和水压（ Shang等（2020）。作者发现，MoO3在水中的溶解度极小，并且在NaCl摩尔浓度超过0.01 m时开始增加。出乎意料的是，尽管可以进行这种比较，但作者并未将其溶解度数据与文献中的相关结果进行比较。实际上，据报道，MoO3在水中的高温溶解度。
