And the article contained the following:

Convenience foods are currently popular among busy, modern consumers. However, the migration of plastics additives and non-intentionally added substances (NIAS) from packaging materials has raised concern about the potential health risks. The migration of nine compounds, including additives (butylated hydroxytoluene and 2,2,4-trimethyl-1,3-pentanediol diisobutyrate), and NIAS that originated from additives degradation products (phenol, 2-ethyl-1-hexanol, acetophenone, 4-propylbenzaldehyde, 2,6-di-tert-butylbenzoquinone, 2,4-di-tert-butylphenol, and methyl-3-(3,5-ditertbutyl-4-hydroxyphenyl)) from convenience food packaging was evaluated in migration tests employing food simulants under real-life consumption and worst-case scenario conditions. Their migration level in the food simulants was quantified by gas chromatog.-mass spectrometry. Most of the compounds had a low frequency of detection and the detected compounds varied depending on the individual samples, regardless of the packaging materials. The worst-case migration tests showed that repetitive microwave heating considerably accelerated the migration and degradation of the additives due to polymer swelling, although a single microwave heating had little effect on the migration. Risk assessment confirmed that the current level of exposure of Korean consumers to the substances from convenience food packaging is unlikely to pose a health risk, even in the worst-case scenario. The experimental process involved the reaction of 2,4-Di-tert-butylphenol(cas: 96-76-4).Application In Synthesis of 2,4-Di-tert-butylphenol

On June 15, 2021, Yang, Fan; Xu, Zibo; Huang, Yuandong; Tsang, Daniel C. W.; Ok, Yong Sik; Zhao, Ling; Qiu, Hao; Xu, Xiaoyun; Cao, Xinde published an article.Quality Control of 2,4-Di-tert-butylphenol The title of the article was Stabilization of dissolvable biochar by soil minerals: Release reduction and organo-mineral complexes formation. And the article contained the following:

Biochar has two existing forms in the moist soil environment, free dissolvable biochar (particle size < 0.45μm) and undissolvable particles (particle size > 0.45μm). The release and decomposition of dissolvable biochar from bulk biochar particles is a primary C loss pathway in biochar-amended soils, which would be reduced by their interactions with soil minerals. Most previous studies focused on the effect of feedstock types and pyrolysis conditions on dissolvable biochar stability, while few studies researched the interaction between dissolvable biochar and soil components, for instance the soil minerals, and its effect on the stability of dissolvable biochar. In this study, bentonite and goethite were selected as model soil minerals because of their differences in structure and surface types: neg. charged 2:1 type phyllosilicate (bentonite) and pos. charged crystalline mineral (goethite). Dry-wet cycling was conducted to determine the effect of these two minerals on the release of dissolvable biochar from walnut shell-derived biochar particles. The stability of dissolvable biochar was measured by chem. oxidation and biodegradation Both soil minerals reduced the release of dissolvable biochar by over 34% with the presence of Ca2+. Mechanisms of “Ca2+ bridging”, “ligand exchange” and “van der Waals attraction” contributed to the formation of dissolvable biochar-bentonite complexes, and Ca2+ promoted dissolvable biochar inserting into bentonite interlayer space, expanding D-spacing from 1.25 nm to 1.55 nm. However, “Ca2+ bridging” barely formed on goethite because of charge repulsion, indicating that the dissolvable biochar was bound with goethite mainly by “van der Waals attraction” and “ligand exchange”. Due to organo-mineral complexes formation, the chem. oxidation extent of dissolvable biochar was reduced by 22.8-36.5%, and the biodegradation extent was reduced by 72.7-85.0%, since the soil minerals are more effective to prevent the dissolvable biochar from being biodegraded. This study proved soil minerals and Ca 2+ were beneficial for enhancing biochar stability, these observations assisted in assessing the biochar ability for long-term carbon sequestration.

On March 15, 2022, Ren, Tianhang; Wang, Yan; Wu, Nan; Qing, Yan; Li, Xingong; Wu, Yiqiang; Liu, Ming published an article.Quality Control of 2,4-Di-tert-butylphenol The title of the article was Degradation of urea-formaldehyde resin residues by a hydrothermal oxidation method into recyclable small molecular organics. And the article contained the following:

Urea-formaldehyde (UF) resin residues and the related product wastes as organic hazardous wastes are difficult to be biodegraded or recycled. In this research, a hydrothermal oxidation method using hydrogen peroxide (H2O2) solution has been developed for the degradation and recycling of UF resin residues. The effects of solution concentration, temperature, and time on the degradation efficiency and products of UF resin residues were studied. Under optimal conditions, i.e., 140°C and 5 wt% H2O2 solution, over 75% of UF resin residues was degraded after 3 h. The degradation efficiency is much higher than that of the traditional hydrothermal treatment or acid hydrolysis method. In addition, results from Fourier transform IR spectroscopy (FTIR), gas chromatog.-mass spectroscopy (GC-MS), NMR spectroscopy (NMR), and X-ray diffraction (XRD) confirmed that H2O2 solution degrades UF resin residues to low mol. compounds, such as alcs., methylal, and amides. This research provides a novel and high-efficient hydrothermal oxidization process for the degradation of UF resin residues, which might be a promising environmentally friendly and low-cost method for the disposal and recycling of industrial UF resin residues. The experimental process involved the reaction of 2,4-Di-tert-butylphenol(cas: 96-76-4).Quality Control of 2,4-Di-tert-butylphenol

Rima, Maya; Trognon, Jeanne; Latapie, Laure; Chbani, Asma; Roques, Christine; El Garah, Fatima published an article in 2022, the title of the article was Seaweed Extracts: A Promising Source of Antibiofilm Agents with Distinct Mechanisms of Action against Pseudomonas aeruginosa.Application In Synthesis of 2,4-Di-tert-butylphenol And the article contains the following content:

The organization of bacteria in biofilms is one of the adaptive resistance mechanisms providing increased protection against conventional treatments. Thus, the search for new antibiofilm agents for medical purposes, especially of natural origin, is currently the object of much attention. The objective of the study presented here was to explore the potential of extracts derived from three seaweeds: the green Ulva lactuca, the brown Stypocaulon scoparium, and the red Pterocladiella capillacea, in terms of their antibiofilm activity against P. aeruginosa. After preparation of extracts by successive maceration in various solvents, their antibiofilm activity was evaluated on biofilm formation and on mature biofilms. Their inhibition and eradication abilities were determined using two complementary methods: crystal violet staining and quantification of adherent bacteria. The effect of active extracts on biofilm morphol. was also investigated by epifluorescence microscopy. Results revealed a promising antibiofilm activity of two extracts (cyclohexane and Et acetate) derived from the green alga by exhibiting a distinct mechanism of action, which was supported by microscopic analyses. The Et acetate extract was further explored for its interaction with tobramycin and colistin. Interestingly, this extract showed a promising synergistic effect with tobramycin. First analyses of the chem. composition of extracts by GC-MS allowed for the identification of several mols. Their implication in the interesting antibiofilm activity is discussed. These findings suggest the ability of the green alga U. lactuca to offer a promising source of bioactive candidates that could have both a preventive and a curative effect in the treatment of biofilms. The experimental process involved the reaction of 2,4-Di-tert-butylphenol(cas: 96-76-4).Application In Synthesis of 2,4-Di-tert-butylphenol

Today, the tendency to use of natural preservatives to increase food security has expanded. In the present study, antibacterial effects of Areca Nut fruit extracts were evaluated against Staphylococcus aureus, Escherichia coli, Salmonella enterica, and Enterobacter aerogenes bacteria using agar disk diffusion technique. Methanol, ethanol, and water were used as solvents for extraction by maceration method, and extracts were analyzed by GC-MS. The antibacterial activity was evaluated using microtiter broth dilution method to determine min. inhibitory concentration (MIC) and min. bactericidal concentration (MBC). Results revealed that all ATCC strains were significantly inhibited by ethanolic and methanolic extracts Escherichia coli produced a significantly larger zone of inhibition for Gentamicin (35 ± 0.65 mm) and Penicillin (25 mm ± 0.56), while Enterobacter aerogenes produced smaller zone of inhibition for Gentamicin (20 ± 0.87 mm) and Penicillin (15 ± 0.87 mm). Also, methanolic extract had considerable antibacterial activity with MIC value of 1.56 mg/mL against Escherichia coli. All of extracts were used to evaluate antibacterial effects in prepared cake, and as a result, all pathogenies were the most sensitive by methanolic extract in 100 mg/L of concentration except Escherichia coli that were more sensitive by ethanolic extract In conclusion, the Areca Nut fruit extracts may be used as a natural preservative in food industries. Future studies should focus on the effect of Areca Nut fruit extracts in bakery and drinking industries.

On October 31, 2020, He, Liao; Sang, Yimin; Yu, Wang; Li, Wanxin; Jiao, Yuhai; Ma, Fujun; Li, FasHeng; Liu, Yuqin; Gu, Qingbao published an article.HPLC of Formula: 96-76-4 The title of the article was Polymerization and Carbonization Behaviors of 2-Methylnaphthalene in Contaminated Soil During Thermal Desorption. And the article contained the following:

Despite the important niche and broad applicability of thermal remediation (TD), little work has been done to discuss chem. reactions of methylnaphthalene contaminated soil. The 2-methylnaphthalene desorption amount (MDA) of TD is studied here under different conditions, and the carbonation (chem. polymerized or condensed) behavior of 2-methylnaphthalene is explained by analyzing the changes of soil organic carbons (SOCs), off-gas products, and surface chem. properties. It indicates that the influence sequence of MDA from high to low is heating time, heating temperatures, and flow rates of carrier gas. MDA increases steadily with the increase of temperatures (200-300°C) but decreases slightly after 300°C; the reason may be the chem. conversion of 2-methylnaphthalene. GC-MS anal. of off-gas confirms that partial 2-methylnaphthalene is polymerized to form 2-methylbenzo[b]thiophene and 2,4-di-tert-butylpheno at 400°C, which is the first step of carbonization process. The XPS results of soil indicate that the C content decreases, but C-(C, H) chem. structure increases, indicating that new carbonaceous substances are generated. A layer of “char” is seen by scanning electron microscope to be left on the surface of the soil particles. As the temperature increases (200-400°C), the SOCs generally decreases from 1.14 to 0.82%, which is the result of the equilibrium between SOCs pyrolysis and 2-methylnaphthalene carbonization. The experimental process involved the reaction of 2,4-Di-tert-butylphenol(cas: 96-76-4).HPLC of Formula: 96-76-4

On January 31, 2020, Jamil, Farrukh; Al-Muhtaseb, Ala’a H.; Naushad, Mu; Baawain, Mahad; Al-Mamun, Abdullah; Saxena, Sandeep K.; Viswanadham, N. published an article.Safety of 2,4-Di-tert-butylphenol The title of the article was Evaluation of synthesized green carbon catalyst from waste date pits for tertiary butylation of phenol. And the article contained the following:

The present study is intended to adopt a facile method for preparing a sulfonated green carbon catalyst from date pits biomass. Catalyst synthesis involves in situ carbonization and sulfonation and it has been characterized by following techniques such as XRD, SEM, EDX, TEM, FTIR, TGA, and BET. Surface and internal morphol. results exhibited that the synthesized sulfonated carbon material possesses a mesoporous structure, while activated carbon possesses a microporous structure. Furthermore, the Fourier transform IR (FTIR) spectra confirmed the presence of acidic groups (-OH, -COOH, and -SO3H) in synthesized sulfonated carbon material. Sulfonated carbon material exhibited high acidity (4.7 mmol/g) and good thermal stability. The application of this catalyst for the tertiary butylation of phenol without using any solvent has been investigated. The phenol alkylation reaction showed maximum conversion at reaction condition: temperature (140°C) with 2 bar (nitrogen gas) pressure with maximum phenol conversion 79.27 wt%, with 68.01% selectivity towards 4TBP+2,4TBP, which is used as an intermediate in antioxidants. The catalyst exhibits comparable catalytic performance up to five reaction cycles. Thus it can be concluded that waste date pits can be successfully employed for green catalyst synthesis and used for reactions involving large mols. The experimental process involved the reaction of 2,4-Di-tert-butylphenol(cas: 96-76-4).Safety of 2,4-Di-tert-butylphenol
