چکیده
An in-depth study of the hydrophobic eutectic mixtures formed by l-menthol (MEN) with butylated hydroxytoluene (BHT), 2-tert-butyl-p-cresol (TBC), and p-cresol (PC) compounds has been carried out, where TBC PC are analogous to BHT species but a different degree steric hindrance around hydroxyl group. Thermal characterization evidenced that BHT/MEN system can be classified as an ideal eutectic, while TBC/MEN PC/MEN behave type V deep solvents (DESs) for wide range compositions point. As shown array experimental theoretical methods, in establishment hydrogen-bond (H-bond) interactions between components is dramatically hampered because molecule, so achievement liquid phase at room temperature composition driven apolar–apolar attractions among alkyl functional groups constituents. Differently, TBC-MEN donor–receptor H-bond main driving force formation DES derives from concurrence electronic factors characterizing molecule. Finally, absence group allows self-association molecules through H-bonded networks already pristine compound, replacement more favorable PC-MEN provides upon mixing these components. Our combined approach, together peculiarity inspected systems, delivered archetypal able shed light onto various contributions ruling structure–properties relationship DESs possibly deepening currently accepted view inherently complex media.

Dihydropyrimidine and amidoalkyl naphthol derivatives have been prepared efficiently in a one-pot synthesis using ZnCl2/urea and ZnCl2/acetamide deep eutectic systems as reaction medium and homogeneous catalyst. This method offers some advantages such as simple procedure, inexpensive solvent and catalyst and good yields of the final products in short reaction times. The use of non-toxic and env...
متن کاملProduction of Natural Butylated Hydroxytoluene as an Antioxidant by Freshwater Phytoplankton(1).
Butylated hydroxytoluene (BHT) is one of the synthetic antioxidant agents commonly used for food additives. In the present study, we determined that four freshwater phytoplankton, including a green alga (Botryococcus braunii Kütz.) and three cyanobacteria [Cylindrospermopsis raciborskii (Wolłosz.) Seenaya et Sabba Raju, Microcystis aeruginosa (Kütz.) and Oscillatoria sp.] were capable of produc...
متن کاملPASS-assisted design, synthesis and antioxidant evaluation of new butylated hydroxytoluene derivatives.
New multipotent antioxidants (MPAOs), namely 1,3,4-thiadiazoles and 1,2,4-triazoles bearing the well-known free radical scavenger butylated hydroxytoluene (BHT), were designed and synthesized using an acid-(base-) catalyzed intramolecular dehydrative cyclization reaction of the corresponding 1-acylthiosemicarbazides. The structure-activity relationship (SAR) of the designed antioxidants was per...

Olivine-type LiMnPO₄/C nanorods were successfully synthesized in a chloride/ethylene glycol-based deep eutectic solvent (DES) at 130 °C for 4 h under atmospheric pressure. As-synthesized samples were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM), Raman spectroscopy, Fourier transform infrared spectroscopy (FTIR) and electroc...
