Figure 6. Reaction course of the esterification reaction with the Brønsted acidic ionic liquid [BMIM][HSO₄] as catalyst. At the beginning of the reaction, the polar educts form a homogenous mixture with the IL. After several minutes in the water bath, a second phase of the nonpolar reaction product is formed. The separation is facilitated since the density of the product is much lower compared to the density of the IL phase
