| Popis: | Diesel lubrication oil contaminated with sunflower oil fuel was exposed to conditions simulating an engine crankcase environment to study the role of copper catalysts in oil mixture thickening. Trace levels of dissolved copper species appear to dominate catalysis of triglyceride autooxidative polymerization with metallic copper surface seemingly only functioning as a dissolution interface. The importance of soluble copper forms was confirmed by replacing copper foil catalysts with a soluble complex, cupric acetylacetonate, to yield equivalent viscosity increases. |
