Exploration of Using Deep Eutectic Solvents to Separate Methyl Palmitate from Simulated Biodiesel Mixtures

Article Preview

Abstract:

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.
