“…In addition to the typical PE bands [19], the spectra of PE-BA exhibit new bands attributed to the reaction product, particularly in the range of 1700-700 cm −1 . The aromatic nature of the graft product is revealed by the band at 1496 cm −1 corresponding to the CC stretching vibration in the plane of the aromatic ring [20][21][22], while the rest of the BA characteristic Second, in order to elucidate the chemistry of the reaction product, FTIR-ATR spectroscopy was performed. The FTIR spectra of PE-BA compared with those of PE and BA are shown in Figure 2.…”

A polyethylene (PE) film surface modification method is proposed via benzoic acid (BA) alkylation grafting to improve the surface affinity to polar substances. The procedure involves sequentially spraying AlCl3 and BA onto the heat-softened PE surface. The occurrence of the alkylation reaction was evaluated through comparative chemical, morphological, and thermal analyses. It was demonstrated that the grafting reaction of BA onto the PE film surface took place, limited to the surface layer, while preserving the bulk properties of PE. The reaction resulted in the formation of aluminum benzoate complexes, which improved the surface affinity to polar compounds. The impact of grafting on the surface properties of PE was further assessed by comparing the behavior of PE films treated with BA and untreated PE films when painted with watercolors. The PE film grafted with BA exhibited increased affinity towards watercolors, providing strong evidence of a change in surface polarity from hydrophobic to hydrophilic. These findings indicate that the proposed methodology effectively renders the PE surface paintable, even with non-toxic water-based inks, making it suitable for applications such as packaging.

Anatomical Structure and Phytochemical Composition of a Rare Species Fraxinus sogdiana Bunge (Oleaceae) Growing in Different Soils in Kazakhstan

et al. 2023

Fraxinus sogdiana Bunge (family Oleaceae) is a rare, relict species, with a disjunctive distribution range. The species is listed in the Red Book of Kazakhstan. The aim of this study was to determine anatomical features and identify the phytochemical composition of F. sogdiana growing in different soils in Kazakhstan. The research objects were vegetative organs collected in the Temirlik River Valley of the Almaty region (the State National Nature Park “Sharyn”) and the Boralday River Valley of the Turkestan region (the Syrdarya–Turkestan Regional Nature Park) in 2020–2022. A comparative anatomical analysis of the vegetative organs of F. sogdiana revealed similarities and differences between the specimens studied. The level of significance was taken at 5%. The main feature identified in the anatomical structure of the F. sogdiana leaves was the presence of large special motor cells in the upper and lower epidermis. A study of the phytochemical composition identified the ten most important biologically active substances with antimicrobial, antitumor, diuretic, and antioxidative properties. In the study areas, soils were different in terms of conditions and time of soil formation. The soil profile of the floodplain terrace of the Temirlik River was found to be stratified with alternating interlayers of light loamy and sandy loam granulometric composition with inclusions of pebbles; differentiation of the soil profile into genetic horizons was poorly pronounced. The soil profile of the floodplain terrace of the Boralday River had a clear differentiation into genetic horizons.

“…It is used in the cosmetics and personal care industries [29]. Benzoic acid is also used as a precursor of other products such as plasticizers, fungal ointments for medical use, and as a calibrating substance for bomb calorimeters [30,31]. In 2020, the global production of benzoic acid amounted to 538,770 tons and it is expected to grow to 628,350 tons by 2026 [32].…”

Kinetics Study of Hydrothermal Degradation of PET Waste into Useful Products

et al. 2021

Kinetics of hydrothermal degradation of colorless polyethylene terephthalate (PET) waste was studied at two temperatures (300 °C and 350 °C) and reaction times from 1 to 240 min. PET waste was decomposed in subcritical water (SubCW) by hydrolysis to terephthalic acid (TPA) and ethylene glycol (EG) as the main products. This was followed by further degradation of TPA to benzoic acid by decarboxylation and degradation of EG to acetaldehyde by a dehydration reaction. Furthermore, by-products such as isophthalic acid (IPA) and 1,4-dioxane were also detected in the reaction mixture. Taking into account these most represented products, a simplified kinetic model describing the degradation of PET has been developed, considering irreversible consecutive reactions that take place as parallel in reaction mixture. The reaction rate constants (k1-k6) for the individual reactions were calculated and it was observed that all reactions follow first-order kinetics.
