摘要：

The reactivity of MoDTC and ZnDTP in hydrocarbon solution was examined in detail under non-oxidizing conditions, These observations revealed increased reaction rates when polar solvents and/or short alkyl groups are encountered. Through the use of molecular modeling, it is shown that the major influences over MoDTC/ZnDTP reactivity are hard/soft acid/base and solvation interactions. As a result of this work, both MoDTC and ZnDTP appear to exist as ion pairs in engine oil formulations.
