“…The catalyst ([Dsim]Cl) used in this study was prepared according to the method given in the literature. [54] Typical Transesterification Procedure: Into a single-necked reaction flask, 1 equivalent of tristearin (0.20 g, 0.22 mmol), 3 equivalents of myristyl alcohol (0.14 g, 0.66 mmol), [Dsim]Cl (0.016 g, 16 mmol%) were added and the resulted mixture was heated at 110 °C (this temperature value was chosen inspired by the studies that previously reported [25][26][27][28] ) for 120 min in a solvent free medium. The reaction flask was cooled and the obtained solid, without isolation of the glycerin byproduct was crystallized from the THF/MeOH (2/8, v/v) solvent mixture to give pure myristyl stearate 1h.…”

“…[22] Studies are still being carried out to synthesize these versatile compounds with more effective and environmentally friendly approaches. [23][24][25][26][27][28] About half a century ago the use of ILs as electrolyte system in batteries has been a remarkable research topic. [29][30][31][32][33] Due to their ability to dissolve many organic and inorganic compounds, they are green solvent candidates that can be used instead of harmful volatile organic solvents in various synthesis reactions.…”

In the present study, triglycerides are subjected to an ionic liquid (IL) catalyzed and solventless transesterification reaction with a series of fatty alcohols in a 1:3 ratio, respectively. In order to prepare the corresponding wax esters, triglycerides trilaurin, trimyristin, and tristearin are treated with fatty alcohols such as lauryl, myristyl, and stearyl alcohol via 1,3‐disulfonic acid imidazolium chloride catalyzed transesterification reaction under environmentally friendly conditions. The optimum duration of the transesterification reaction is determined by proton nuclear magnetic resonance spectroscopy and the progress of the reaction can also be easily followed by thin layer chromatography. According to these studies, the reaction takes about 2 h to complete and the corresponding wax esters are obtained successfully by recrystallization from suitable solvent mixture without tedious work‐up in good to excellent yields (86–100%). Practical Applications: With this sustainable method, a homologous series of wax esters can be successfully synthesized as bio‐based thermal energy storage materials. The prominent aspect of this solventless method is that it allows the preparation of wax esters directly from triglycerides via an ionic liquid catalyzed process both in laboratory and industrial scale.
