    • Professor Aggarwal and co-workers have isolated and characterized the modified imidazolium salt which is formed via addition of the azolium salt to aldehyde. After performing the necessary control studies, revealed was that upon reuse, the sequestered aldehyde derivatives in additional runs, the increase in overall yield in iterative recycling events was due to the sequestered material.

    • Using a water content of 30%, a ratio of 7:1 can be determined using the formula weights of both water and sulfonic acid headgroup (1 g sulfonic acid headgroup (FW 385.44 g/mol) and 300 mg water (30% FW 18.02). A value of 30% was used considering that a higher water content would result in a drop in conversion. Baseline values being 10-30%. For a discusion on the parameters associated in proton dissociation from sulfonic acid headgroups due to hydration, see: S.J. Paddison, L.R. Pratt, T.A. Zawodzinski Jr., J. Phys. Chem.
