    • The nitrogen contents of parent and modified NMMS are 3.0% and below 0.1%, respectively. Because the precision of the elemental analyzer (Perkin-Elmer 2400) is also limited to 0.1%, the residual nitrogen content of modified NMMS is at most 3.3% from the quaternary ammonium.

    • note
    • In esterification, the nonpolar solvent xylene is needed to drive the dehydration. In our silylation process, the silyl functionalization is rapid and effective when using ethanol as the solvent. This is due to the high surfactant solubility. In contrast, the process is slow and ineffective in toluene with low surfactant solubility.
