最近，蒸汽成核速率测量的准确性已大大提高。然而，当实验条件变得接近所研究系统的临界参数的值时，发现实验结果与理论预测之间存在显着差异。一些研究发现，只有在一个狭窄的范围内的成核条件的结果和理论之间的协议。因此，研究其他体系的成核过程，以获得指导成核理论发展的新信息是合适的。醇类是研究最多的一类化合物，但目前还没有关于正辛醇蒸汽成核的实验数据。本文研究了正辛醇在六氟化硫溶液中的均相成核反应。将二元混合物的临界压力与液滴近似中使用体相液体表面张力计算的拉普拉斯压力进行比较，表明载气具有莫尔的..
Recently, the accuracy of vapor nucleation rate measurements has increased substantially. However, when experimental conditions become close to the values to the critical parameters of investigated systems, significant discrepancies were found between the experimental results and theoretical predictions. Some studies have found agreement between results and theory only within a narrow range of nucleation conditions. Therefore, it is appropriate to investigate the nucleation of additional systems to obtain new information to guide nucleation theory development. Alcohols are the most studied class of chemical compounds, but currently there are no experimental data on n-octanol vapor nucleation. The present study is devoted to the investigations of the homogeneous nucleation of the n-octanol in sulfur hexafluoride. Comparison of the critical pressures for binary mixture with the Laplace pressure calculated in the droplet approximation using the bulk liquid surface tension shows that the carrier gas has a mor...
