Samples of the solvent and IL phases were analyzed by GC-MS
and 1H NMR, respectively. Aniline conversion was quantified
using the internal standard method with mesitylene as internal
standard. 1H NMR spectra was measured in DMSO-d6 and
collected with a relaxation time of two times T1. Product yield of
diphenylurea and aniline conversion was quantified using the
internal standard method with [BMIM]Cl.
