On March 31, 2020, Ben Harb, Marwa; Abubshait, Samar; Etteyeb, Naceur; Kamoun, Madiha; Dhouib, Adnene published an article.Category: alcohols-buliding-blocks The title of the article was Olive leaf extract as a green corrosion inhibitor of reinforced concrete contaminated with seawater. And the article contained the following:

In reinforced concrete, a high alk. medium, steel is commonly protected by formation a passive oxide film. Nevertheless, contamination with chlorides or carbonation causes the deterioration of protective film and the initiation of pitting corrosion. Hence, the need to enrich the fresh concrete solution with a good corrosion inhibitor. In accordance with green chem. to evade toxicity and minimize waste, we have chosen to replace the usual inhibitors with an alternative not only ecol. but also derived from biol. wastes, in a perspective of circular economy emphasizing that waste can offer important compounds at an affordable price and easily available. In this context this work seeks to valorize the dried olive leaves extract as an inhibitor in alk. chloride solution (pH 13). The targeted plant was grown in arid zones of Saudi Arabia and their leaves are usually disposed of as solid waste or animal feed. Four extraction solvents of different polarities were used; methanol, Et acetate, dichloromethane and hexane. The anticorrosive activity was performed using different electrochem. techniques; polarization curves, electrochem. impedance spectroscopy and Mott-Schottky analyses. The polarization studies proved that extract from olive leaves is a mixed type inhibitor in a solution of NaOH (0.1 M) + NaCl (0.5 M),with a predominant anodic effectiveness. The best inhibition of 91.9% is provided with methanol extract GC-MS anal. showed the presence of compounds containing the heteroatoms N and O with the 蟺 electrons which are responsible for the corrosion inhibition activity. The olive leaves have been found to be high in phenol and flavonoid content. Inhibition efficiency of the olive leaves extracts increases with the polarity of extraction solvents but also it appears that it depends on another factors. The experimental process involved the reaction of 2,4-Di-tert-butylphenol(cas: 96-76-4).Category: alcohols-buliding-blocks

And the article contained the following:

The concentrations and distributions of selected alkylphenols (APs; 4-nonylphenols, 4-n-octylphenol, 4-tert-octylphenol, 4-tert-butylphenol and 2,4-di-tert-butylphenol) in water, sediment and aquatic organism samples in the Pearl River networks were determined using gas chromatog.-mass spectrometry. The results showed that 4-nonylphenols (NPs) were dominant in both water samples and sediment samples. For APs, downtown and populated regions showed higher concentrations than rural regions; furthermore, the concentrations of APs in eastern tributaries were higher than those in western tributaries. In aquatic organism samples, the content range of APs, NPs, and octylphenols (OPs; 4-n-octylphenol and 4-tert-octylphenol) were 174.74-648.10 ng/g, 143.95-582.51 ng/g, and 8.10-37.10 ng/g, resp., with mean values of 346.52, 281.90, and 24.13 ng/g, accordingly. The accumulated level of APs in nine different species of aquatic organism species declined as follows: perch (Lateolabrax japonicus) > bighead fish (Aristichthys nobilis) > silver carp (Hypophthalmichthys molitrix) > carp (Cyprinus carpio) > barbel chub (Squaliobarbus curriculus) > shellfish (Corbicula fluminea) > grass carp (Ctenopharyngodon idellus) > cyprinid fish (Megalobrama hoffmanni) > shrimp (Macrobranchium nipponense). Carnivorous and filter-feeding fish tended to accumulate more APs than other dietic fish, shellfish and shrimps.

The genus Bidens a member of family Compositae, is widely documented as an ethno-medicinally important genus of plants. In the present study, anticancer potential of three ethno-medicinally important species i.e., B. bipinnata, B. biternata and B. pilosa were tested. For in-vitro evaluation, an MTT (Thiazolyl blue tetrazolium bromide) assay was performed against cervical cancer cells (HeLa), hepatocellular carcinoma (HepG), and adenocarcinoma human alveolar basal epithelial cells (A549). For in vivo evaluation, Artemia salina, Danio rerio, and Caenorhabditis elegans were used. Among all the tested extracts, the ethanol extract of B. biternata appeared to have highest anticancer activity, and the compounds responsible for this activity were identified to be Tris (2,4-di-tert-butylphenyl), 4-hydroxy-2,4-dimethoxychalcone, and 2,4-di-tert-butylphenol. This is the first report of the isolation of Tris (2,4-di-tert-butylphenyl) phosphate from the genus Bidens and the first report of 4-hydroxy-2,4-dimethoxychalcone and 2,4-di-tert-butylphenol from B. biternata. Among the isolated compounds, 4-hydroxy-2,4-dimethoxychalcone showed the highest anticancer activity with an LD50 value of 236.7渭g/mL. Therefore, this compound carries promising potential for being established as a pharmaceutical for chemoprevention and chemotherapy.

And the article contained the following:

Plastic pollution is a source of chem. to the environment and wildlife. Despite the ubiquity of plastic pollution and thus plastic additive in the environment, plastic additives have been studied to a limited extend. As a prerequisite to a study aiming to evaluate the leaching of a common additive used as an antioxidant (Irgafos 168) from polyethylene microparticles, an inventory of the potential background contamination of the laboratory workplace was done. In this study, Irgafos 168 (tris(2,4-ditert-butylphenyl) phosphite) and its oxidized form (tris (2,4-ditert-butylphenyl) phosphate) were quantified in different laboratory reagents, including the plastic packaging and the powders, using Pyrolysis-GC/MS. At least one form of Irgafos 168 was detected in all tested laboratory reagents with higher concentrations in caps and bottles as compared to the powders. Addnl., oxidized Irgafos 168 was also found in the reverse osmosed and deionized water container used in the laboratory The same profile of contamination, i.e. higher concentration of the oxidized form and higher concentrations in acidic reagents, was observed when comparing the reagent and their resp. containers suggesting that the additive is leaching from the container into the powder. Overall, this study demonstrates that the antioxidant additive Irgafos 168 is ubiquitous in the laboratory workplace. Plastic additives such as Irgafos 168 can therefore largely interfere and biased ecotoxicol. and toxicol. studies especially using environmentally relevant concentrations of microplastics. The source, fate and effects of plastic additive from plastic debris should be carefully considered in future studies that require setting up methods to overcome these contaminations. The experimental process involved the reaction of 2,4-Di-tert-butylphenol(cas: 96-76-4).Name: 2,4-Di-tert-butylphenol

Lu, Yao; Liu, Yaqiong; Lv, Jiawei; Ma, Yanli; Guan, Xiaolei published an article in 2020, the title of the article was Changes in the physicochemical components, polyphenol profile, and flavor of persimmon wine during spontaneous and inoculated fermentation.Name: 2,4-Di-tert-butylphenol And the article contains the following content:

Changes in the oenol. parameters, total phenols, total flavonoids, and individual phenols of persimmon during spontaneous and inoculated fermentation were investigated. The volatile compounds and sensory character of the persimmon wine were compared and evaluated simultaneously. Results show that at the end of fermentation, spontaneous persimmon wine (SPW) has higher contents of total flavonoids, total phenols yet lower concentrations of alc. and volatile compounds than inoculated persimmon wine (IPW). Catechin, salicylic acid, quercetin, and vanillic acid were the main phenolic compounds in both types of persimmon wine. There are six volatile components in the IPW with an OAV greater than 1, which are isoamyl acetate, Et hexanoate, Me octanoate, Et octanoate, phenethyl acetate, and 2, 4-di-tert-butylphenol, and these compounds contribute to the IPW with brandy and fruity sensory properties, while only three volatile components in SPW have OAV greater than 1, which are isoamyl acetate, Et hexanoate, and Et octanoate. Spontaneous fermentation increased the proportion of esters and alcs. in the overall volatile compounds During sensory evaluation, IPW was characterized by “brandy,” “bitterness,” and low “sweetness,” and SPW has a high score of “sweetness,” “balance,” desirable “color,” and “body.
