测定了甲硫醇在各种胺类水溶液中的溶解度。硫醇的化学溶解度可以通过考虑硫醇和胺的酸碱性质来预测。用化学平衡常数从实验结果中分离出50wt%甲基二乙醇胺的化学和物理溶解度。在中等酸负荷下，化学溶解度降低，物理溶解度占主导地位。这种方法已经扩展到单乙醇胺、二乙醇胺和二乙醇胺的水溶液。
The solubilities of methyl mercaptan in a variety of aqueous amine solutions have been measured. Mercaptan chemical solubility can be predicted by consideration of acid-base properties of the mercaptan and amine. Chemical equilibrium constants have been used to separate the chemical and physical solubilities from experimental results for 50 wt % methyldiethanolamine. At moderate acid loadings, the chemical solubility is diminished and the physical solubility dominates. This methodology has been extended to aqueous solutions of monoethanolamine, diethanolamine, and diglycolamine.
