Global food waste has a huge impact on the environment, as it is source of greenhouse gas emissions and wasted natural resources. Across world, over 30% lost or each year. Aside from this, industry, well, one biggest sources agro-industrial by-products, which can be valorized used for different purposes.

Global food waste has a huge impact on the environment, as it is source of greenhouse gas (GHG) emissions and wasted natural resources. Across world, over 30% lost or each year. Aside from this, industry, well, one biggest sources agro-industrial by-products, which can be valorized used for different purposes. Such good bioactive organic compounds extracted without al-tering their properties, where deep eutectic solvents (DESs) serve green excel-lent replacement volatile solvents. Isolated...
The Menshutkin reaction represents the alkylation of tertiary amines by alkyl halide where reactants are neutral and products, quaternary ammonium salts, two ions with opposite signs. most commonly used organic solvents in quaternization reactions volatile (VOSs), namely acetone, anhydrous benzene, dry dichloromethane (DCM), dimethylformamide (DMF) acetonitrile (ACN). purpose this work was to examine eutectic as a “greener” alternative conventional so that take place accordance principles...
GC and MS were used for the analysis of Croatian Centaurium erythraea Rafn essential oil (obtained by hydrodistillation) headspace (applying solid-phase microextraction). The contained numerous monoterpene hydrocarbons (the major ones terpinene-4-ol, methone, p-cymene, γ-terpinene limonene). Oxygenated monoterpenes present in oil, while 1,8-cineole, bornyl acetate verbenone only headspace. High percentages toluene naphthalene found, followed hemimellitene. Lot similarities observed with...
Sample displacement chromatography ( SDC ) in reversed‐phase and ion‐exchange modes was introduced approximately 20 years ago. This method first used for the preparative purification of peptides proteins. Recently, mode also successfully enrichment low‐abundance proteins from human plasma. In this paper, use separation plasma hydrophobic interaction is demonstrated. By two or more columns coupled series during sample application, subsequent elution detached parallel, additional bound...
The quaternization reactions of nicotinamide, with different electrophiles: methyl iodide and substituted 2-bromoacetophenones (4-Cl, 4-Br, 4-H, 4-CH₃, 4-F, 4-OCH₃, 4-Ph, 2-OCH₃, 4-NO₂) are reported. preparations were carried out by conventional synthesis under microwave irradiation in absolute ethanol acetone. performed dielectric heating significantly improved yield, up to 8 times, shortened down the reaction time from ca. one day conventional, 10⁻20 min. structures synthesized compounds...
The synthesis of 14 hydrazone compounds derived from pyridoxal, pyridine-4-carbaldehyde, and quinoline-2-carbaldehyde using two methods, conventional method in deep eutectic solvents (DESs) effective combination ultrasound DESs, is presented this paper. In addition, the possibility 12 choline chloride (ChCl)-based DESs as an alternative to organic was investigated. results show that application not only improves reaction yield but also shortens time. prepared synthesized at room temperature...
In this study, reactions of quaternization under microwave heating pyridine, α-picoline, pyridine-4-aldoxime, pyridine-2aldoxime, nicotinamide, isonicotinamide and pyridoxal oxime with different electrophiles: 2-bromo-4'-nitroacetophenone, 2-amino-4chloro-methylthiazole hydrochloride, methyl iodide, 1,3-diiodopropane 1,3-dibromopropane are reported.The synthesis yield by dielectric is improved reaction time shortened compared to conventional heating.The structure obtained molecules were...
