Fig. 2. Experiments 18 (100 g dm⁻³ MS4Å) and 19 (32.9 g dm⁻³ SiO₂): (A) % conversion of rutin to rutin octanoate product as monitored with LC-MS during the 96 h reactions; (B) plot of t/q_tvs. t confirming a pseudo-second order conversion reaction; (C) LC-MS spectra comparison of the qualitative profile of the methanolic phases for each experiment; [M–H]⁻ shown (g mol⁻¹).
