Reactions of Polycyclic Alkylaromatics. 1. Pathways, Kinetics, and Mechanisms for 1-Dodecylpyrene Pyrolysis C. Michael Smith and Phillip E. Savage* Department of Chemical Engineering, T h e University of Michigan, A n n Arbor, Michigan 48109-2136

1-Dodecylpyrene (DDP) was pyrolyzed at concentrations between 0.0007 and 0.47 M in a benzene diluent, a t temperatures from 375 to 450 "C. Product yields and selectivities were functions of both the conversion and the initial concentration. For instance, DDP pyrolysis at low conversions (
