Effect of Intermolecular Interaction on Stability of Asphaltene-Hydrogen Donor System
文献摘要：
The stability of three asphaltene-hydrogen donor systems,namely asphaltene-1-methylnaphthalene,asphaltene-tetralin,and asphaltene-decalin,with a mass ratio of 1:10 was investigated using the Turbiscan stability analyzer.The interactions between hydrogen donor molecules and asphaltene units were simulated and calculated using Gaussian and Multiwfn,and then,noncovalent interaction analysis was performed.The results showed that the stability of the three asphaltene-hydrogen donor systems decreased as follows:asphaltene-1-methylnaphthalene＞asphaltene-tetralin＞asphaltene-decalin.The stability differences among the three systems were due to the different interactions between the hydrogen donor molecules and the asphaltene unit.The T-stacking interaction strength between the hydrogen donor molecules and the asphaltene units decreased as follows:1-methylnaphthalene-asphaltene unit＞tetralin-asphaltene unit＞decalin-asphaltene unit.Qualitative analysis indicates that the T-stacking interactions between the hydrogen donor molecules and the asphaltene units were mainly van der Waals forces,and the proportions of hydrogen bonds in the weak interaction differed among the systems.
