In this study, we have calculated the thermodynamic properties, especially in determining the theoretical acidic properties and pKa values of organic compounds, as enthalpy (ΔH, kcal/mol), heat capacity (C, cal/Kmol), entropy (ΔS, cal/Kmol), and free energy (ΔG, kcal/mol) of 47 different solvents with the MOPAC 2016 computer program at 298 K used in semi-empirical quantum methods (PM7, PM6, PM6-DH2, RM1, PM3, AM1, and MNDO). Evaluations are made between these values and the used methods. At the same time, a data bank is created with obtained values for the researchers who will do scientific study for the theoretical pKa.

通过用于确定理论pKa的半经验量子方法计算最重要的47种不同溶剂的热力学性质以创建信息数据库

在这项研究中,我们计算了热力学性质,特别是在确定有机化合物的理论酸性性质和pKa值时,包括焓(ΔH,千卡/摩尔),热容(C,cal / Kmol),熵(ΔS)。,cal / Kmol)和47种不同溶剂的自由能(ΔG,kcal / mol)和MOPAC 2016计算机程序在298 K下用于半经验量子方法(PM7,PM6,PM6-DH2,RM1,PM3, AM1和MNDO)。在这些值和所使用的方法之间进行评估。同时,将创建一个数据库,其中包含将为理论pKa进行科学研究的研究人员所获得的价值。
