Synthesis And Characterization of NovelDeep Eutectic Solvents and PotentialApplicationinMicellarSystems

Abstract

This section we have synthesis of five amino acid-based DESs made of L-aspartic acid, L-tyrosine, L-glutamine, L-Phenylalanine, L-methionine are combined with ChCl as a hydrogen bond acceptor to generate DES1, DES2, DES3, DES4 and DES5, respectively. The DESs operated at atmospheric pressure of 80°C and 1:2 molar ratios. FTIR spectra of the implicated bonds show changes in the representative peaks and band broadening. DESs underwent Fourier transform infrared spectroscopy (FT-IR) examination to reveal their chemical composition. Synthesized DESs is many applications CO2 capture, and several pharmaceuticals, drug solubilization, nanotechnology, improving oil recovery, the purification of biodiesel, other technological implementations etc. newlineThis section we have discuss the effects of three novel synthesized biologically active deep eutectic solvents (DESs) on the micellar characteristics of surfactants viz. anionic sodium dodecyl sulfate (SDS), cationic cetyltrimethylammonium bromide (CTAB), and non-ionic Triton X-100 (TX-100). Surface tension, viscosity, UV-visible, fluorescence, and FTIR spectroscopy are a few of the techniques used to study the interactions of surfactants viz. sodium dodecyl sulfate, cetyltrimethylammonium bromide, and Triton X-100 within 5 and 10 wt% of three novels biological DESs. The presence and absence of 5 and 10 wt% of the three-novel biological DESs in an aqueous solution is used to study the critical micelle concentration (CMC) and various interfacial characteristics including CMC, the efficiency of adsorption, the maximum surface excess concentration, the packing parameter, the minimum area per molecule, and the surface pressure at CMC, is assessed by the surface tension method. The calculated fluorescence data and those obtained using surface tension and UV-visible methods correspond well. The interactions that cause changes in the structure of the surfactant self-assemblies within aqueous DESs were investigated using FTIR technique. It is significant to highlight that the prese
