Special Issue Information

Dear Colleagues,

This is a holistic Special Issue that will cover state-of-the-art of innovative analytical methodologies that can be employed in virtually any research field, from science and engineering to biochemistry, chemistry, and green-chemistry and to (bio)polymers, biology, ecology, environment and pollution, microbiology, agri-food (e.g., dairy, feed, pet food, meat, juices, refrigerants, beer, wine), enzymology, biotechnology, biomedicine, biomaterials, bioengineering, etc. The main focus of this Special Issue is to describe the development and optimization of novel analytical methodologies for the selective extraction, separation, identification, and purification of high-added value compounds or fractions from virtually any matrix, such as from chemicals, agriculture, and industrial by-products and wastes; microbial metabolites from fermentation processes by yeasts, molds and bacteria; or compounds from algae and microalgae. Any type of high-added value compound, such as  chemicals, food, cosmetics, pharmaceuticals, nutraceuticals, bioenergy (e.g., biofuel, bioethanol, biobutanol, biohydrogen), and biofertilizers will be considered. Likewise, the application of any type of analytical methodology, such as  separation techniques (TLC, HPLC, GLC), mass spectrometry (GC-MSn, LC-MSn, HRMS, etc.), and spectroscopy (NMR, NIR, FT-IR, FTIR-PAS) as well as genomics, proteomics, transcriptomics, metabolomics, and lipidomics approaches are also welcome.

Mandelic acid is a valuable chemical that is commonly used in the synthesis of various drugs, in antibacterial products, and as a skin care agent in cosmetics. As it is an important chemical, various methods are used to synthesize and extract this compound. However, the yields of the used processes is not significant. A dilute aqueous solution is obtained when using several production methods, such as a fermentation, etc. In this study, the reactive extraction of mandelic acid from aqueous solutions using tri-n-octylamine extractant at 298.15 K was investigated. Dimethyl phthalate (DMP), methyl isobutyl ketone (MIBK), 2-octanone, 1-octanol, n-pentane, octyl acetate, and toluene were used as diluents. The batch extraction results of the mandelic acid experiments were obtained for the development of a process design. Calculations of the loading factor (Z), distribution coefficient (D), and extraction efficiency (E%) were based on the experimental data. The highest separation yield was obtained as 98.13% for 0.458 mol.L−1 of tri-n-octylamine concentration in DMP. The overall extraction constants were analyzed for the complex of acid-amine by the Bizek approach, including K11, K12, and K23. Full article
