对苯二酚 (HQ) 在特定热力学条件下在各种气体分子存在下形成有机包合物。对于某些系统，迄今为止的文献中笼形相平衡和占有率数据非常稀少或不存在。这项工作介绍了在约 288 至 354 K 的扩展温度范围内对 CO2-HQ、CH4-HQ 和 N2-HQ 包合物获得的实验结果。确定了这些系统的形成/解离压力以及平衡包合物形成条件下的占有率。实验还介绍并讨论了结晶溶剂的影响以及气压对 HQ 溶解度的影响。我们的实验结果与已经发表的实验和建模数据之间取得了很好的一致性。我们的结果表明包合物占有率与温度有明显的依赖性。发现 CO2-HQ 和 CH4-HQ 包合物获得的平衡曲线彼此非常接近。报告中提出的结果...
Hydroquinone (HQ) forms organic clathrates in the presence of various gas molecules in specific thermodynamic conditions. For some systems, clathrate phase equilibrium and occupancy data are very scarce or inexistent in literature to date. This work presents experimental results obtained for the CO2–HQ, CH4–HQ, and N2–HQ clathrates, in an extended range of temperature from about 288 to 354 K. Formation/dissociation pressures, and occupancies at the equilibrium clathrate forming conditions, were determined for these systems. Experiments showing the influence of the crystallization solvent, and the effect of the gas pressure on HQ solubility, were also presented and discussed. A good agreement is obtained between our experimental results and the already published experimental and modeling data. Our results show a clear dependency of the clathrate occupancy with temperature. The equilibrium curves obtained for CO2–HQ and CH4–HQ clathrates were found to be very close to each other. The results presented in th...
