Abstract
Two alkyl-bridged aromatic compounds, with molecular weights of 899.70 g/mol and 1127.99 g/mol, were thermally cracked with 1-hexadecene, 1- octadecene, or trans-stilbene, in a batch microreactor at 375–430 °C for 15 to 45 min. The objective of the study was to investigate the kinetics of the addition reactions between the olefins and asphaltene model compounds. Reaction products were analyzed by gas chromatography, high-performance liquid chromatography, matrix-assisted laser desorption/ionization mass spectrometry (MALDI-MS), and proton nuclear magnetic resonance (1H-NMR) spectroscopy. Kinetic data indicate a first-order reaction in model compound concentration, with energetics consistent with a free-radical chain mechanism. Tandem MS/MS and 1H-NMR spectra of the products are consistent with olefin addition through the alkyl bridge of the bridged aromatics. The results imply that the addition products are able to abstract hydrogen to give detectable products faster than they decompose, and that they can react even more readily than the parent compounds.
