Adsorption Phenomena

Adsorption of the components of deep eutectic solvent ethaline (ethylene glycol and choline chloride) on mercury electrode is investigated by electrocapillary measurements. It is determined that choline cations are mainly adsorbed on the negatively charged surface of mercury, while chloride anions are mainly adsorbed on the positively charged surface. The corresponding values of free energies of adsorption and interactions of adsorbate and solvent with metal are calculated and analyzed. An anomalous increase in both the apparent value of the adsorption at limiting coverage and the free energy of the interaction of the choline cation with mercury is observed in the transition from aqueous to ethylene glycol solutions, which is explained by the formation of complexes in a surface layer that exist in deep eutectic solvents and are capable of adsorbing on the electrode surface. The free energy of interaction with the mercury surface is higher than the energy of squeezing out from the volume of the solution onto its surface, which indicates the specific interaction of the adsorbate with mercury. A marked decrease in interfacial tension on both branches of the electrocapillary curve is observed when water is added to ethaline.

Biodiesel Purification

Biodiesel purification from the crude biodiesel product has attracted much attention in recent years, and one low cost and simple purification process is urgent to explore. The separation of methyl palmitate from the crude biodiesel products is a key point. In this work, a series of choline chloride based deep eutectic solvents (DESs) is explored as a solvent for separation of methyl palmitate from the simulated biodiesel product. The work showed that the choline chloride-ethylene glycol DES had a excellent effect on the separation of methyl palmitate, and high purity of methyl palmitate were obtained with the choline chloride to ethlene glycol ratio decrease or with the choline chloride-ethylene glycol DES to biodiesel ratio increase.
