The reactions of petroleum asphaltenes generally involve a complex network of parallel and series reaction paths whose fundamentals are obscured in the overall system complexity. Experiments are therefore frequently summarized in global terms, e.g., solubility or boiling point fractions; little is usually resolved about the fundamentals that are also the key to the development of optimization strategies. This motivates the approach of Chemical Modeling, which permits the pathways, kinetics and mechanism of the reactions of macromolecules to be interpreted in terms of relevant model compound results. Chemical Modeling is analogous to the use of mathematical transforms. The real macromolecular system is transformed (T) into a set of model systems, so chosen because experiments thereon provide high yields of fundamental information. Relating this information to the real macromolecular system is through the inversion (T/sup -1/) of the original transform. The rules by which T and T/sup -1/ are accomplished are governed by the differences between the macromolecule and the model system, e.g., molecular weight, but are largely independent of the details of the specific macromolecule to which they are applied.
