| Summary: | Omega-3 poly unsaturated fatty acids (PUFA) particularly eicosapentaenoic acid (EPA),
and docosahexaenoic acid (DHA), have many health benefits including reducing the risk of cancer
and cardiovascular disease. Recently, the use of ionic liquids (ILs) in lipid extraction from microalgae
provides the potential to overcome common drawbacks, offers several other benefits. To date, very
limited researches are available to focus on extracting microalgae lipid and PUFA in particular by
using ILs. The objective of current work is to screen the potential ILs that can be applied in EPA
extraction. In this study, fast ILs screening was performed with the help of a conductor like screening
model for real solvents (COSMO-RS) and the ILs with higher capacity values for use in extraction
of EPA were compared. According to the results, the highest capacity for EPA extraction among
352 screened cation/anion combinations belongs to [TMAm][SO4]. It is expected to achieve a higher
yield of EPA once applying this combination as the solvent in the process of extraction. ILs with small
anions were observed to have higher capacities, as well possessing higher charge density compared to
larger ones, and therefore, they are more preferable for extraction purposes. Moreover, shorter alkyl
chain cations are preferred when using imidazolium-based IL, which agrees with experimental data. |
