Summary: A mathematical model of the acid catalyzed 1,3‐propanediol polymerization has been developed. Two catalysts investigated include sulfuric acid and superacid (tetrafluoroethane sulfonic acid or triflic acid). Based on a detailed reaction mechanism, population and mass balance equations have been derived for small molecules as well as for polymeric species of numerous chain distributions, which...
This work correlates the basicity of various axial ligands (AL), including triethylamine, methylimidazole, pyridine, acetonitrile or water, with the efficacy of catalytic oxidation of 2,6-di-tert-butylphenol by Co(salen)(AL) in CO2-expanded methylene chloride. Further, Co(salen)(AL)O2 abstracts hydrogen atoms from substrates of high to intermediate reactivity (BDECH ≤~90 kcal/mol).
