在这里,我们提出了一个相关性,以估计所需的Lennard-Jones(LJ)参数的氟原子类型的建模在我们的力场氢氟烯烃(HFO)。这将使得具有任何数量的键合氟原子的HFO化合物的参数化一致。此外,我们提供了氯原子类型的新LJ参数,通过微调与氢氯氟烯烃(HCFO)反式-1-氯-3,3,3-三氟丙烯(HCFO-1233 zd(E))和2-氯-3,3,3-三氟丙烯(HCFO-1233 xf)的最新实验数据的一致性进行了优化。引入的相关性和重新优化的氯参数将形成HFO力场的系统扩展的基础-最初是为氟化丙烯开发的-氟化丁烯和HCFO化合物。用Gibbs EnergyMonteCarlo模拟方法对3,3,3-三氟-1-丙烯(HFO-1243 zf)、顺式和反式-1,1,1,4,4,4-六氟丁烯(HFO-1336 mzz(Z/E))、HCFO-1233 zd(E)、HCFO-1233 xf和顺式-1-氯-2,3,3,3-四氟丙烯(HCFO-1224 yd(Z))的汽液平衡进行了验证。在这里,我们提供了模拟结果的蒸汽压,饱和密度,和这些化合物的汽化热,以及估计其临界特性和正常沸点与参考数据相比。
We here present a correlation to estimate the required Lennard-Jones (LJ) parameters for the modeling of the fluorine atom type in our force field for hydrofluoroolefins (HFOs). This shall enable a consistent parametrization for HFO compounds with any number of bonded fluorine atoms. Additionally, we provide new LJ parameters for the chlorine atom type, optimized by fine-tuning agreement with recent experimental data for the hydrochlorofluoroolefins (HCFOs)trans-1-chloro-3,3,3-trifluoropropene (HCFO-1233zd(E)) and 2-chloro-3,3,3-trifluoropropene (HCFO-1233xf). Both the introduced correlation and the reoptimized chlorine parameter shall form the basis for a systematic extension of the HFO force field—originally developed for fluorinated propenes—to fluorinated butenes and HCFO compounds. The parametrization approach is tested by Gibbs Ensemble Monte Carlo simulations on the vapor–liquid equilibria of 3,3,3-trifluoro-1-propene (HFO-1243zf),cis- andtrans-1,1,1,4,4,4-hexafluorobutene (HFO-1336mzz(Z/E)), HCFO-1233zd(E), HCFO-1233xf, andcis-1-chloro-2,3,3,3-tetrafluoropropene (HCFO-1224yd(Z)). We here provide simulation results for the vapor pressures, saturated densities, and heats of vaporization of these compounds, as well as estimates for their critical properties and normal boiling points in comparison with reference data.
