Jam, Neda; Hajimohammadi, Reza; Gharbani, Parvin; Mehrizad, Ali published an article in 2021, the title of the article was Evaluation of antibacterial activity of aqueous, ethanolic and methanolic extracts of areca nut fruit on selected bacteria.Product Details of 96-76-4 And the article contains the following content:

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. The experimental process involved the reaction of 2,4-Di-tert-butylphenol(cas: 96-76-4).Product Details of 96-76-4

On February 29, 2008, Steinhauer, K.; Goroncy-Bermes, P. published an article.Application of 4719-04-4 The title of the article was Treatment of water-based metalworking fluids to prevent hypersensitivity pneumonitis associated with Mycobacterium spp.. And the article contained the following:

To prevent further outbreaks of hypersensitivity pneumonitis (HP), biocides are required which are capable of protecting water-based coolants from proliferating mycobacteria. The aim of this study was therefore, to test different biocide preparations on their mycobactericidal activity. Minimal inhibitory concentration values were determined for Mycobacterium chelonae and Mycobacterium immunogenum for triazine-based, methyloxazolidine-based, N/O-formal-based biocidal formulations. All biocides were effective already at a low dosage (<0.05%) irresp. of the presence or absence of organic soiling, except for one N/O-formal-based formulation containing Kathon 886 (CMI). Quenching of CMI in the presence of organic soiling was found to account for loss in efficacy as determined by high-performance liquid chromatog. measurement. Preservation tests were carried out to investigate the efficacy of the biocidal preparations under practical conditions. Results indicate that methyloxazolidine-based biocidal preparations were most effective to prevent coolants from microbial contamination including rapidly growing mycobacteria. Furthermore, it could be demonstrated that common dipslides can be used to easily monitor coolants for contamination by mycobacteria. Our data does not support the hypothesis that mycobacterial proliferation is enhanced by the reduction of competitive microbial population by biocides such as triazines as described earlier but rather suggests a protective effect of biocides regarding mycobacteria in the presence of competitive microbial flora, thereby preventing further outbreaks of HP. The experimental process involved the reaction of 2,2',2''-(1,3,5-Triazinane-1,3,5-triyl)triethanol(cas: 4719-04-4).Application of 4719-04-4

On June 30, 1987, Robert, Dominique; Gawad, Hoda Abdel; Riess, Jean G. published an article.SDS of cas: 2160-93-2 The title of the article was Fluorophosphoranes as Lewis acids. The conditions of access to hexacoordinated neutral adducts via the intramolecular addition of an electron donor. And the article contained the following:

The preparation of bicyclic neutral hexacoordinated fluorophosphorus adducts (I) from RPF4 (R = F, Me, Ph) and (Me3SiOCH2CH2)2X (X = O, S, NH, NMe, NCMe3, NPh) was examined Adduct I was formed predominantly only in the case where R = F and X = S. In all the other cases there was a strong tendency to form ionic species. The 8-membered dialkoxyfluorophosphorane model precursor II (X = CH2) does not form easily, and the driving force towards the formation of the very stable RPF5- anions and of tetracoordinated phosphorylated species leads to its easy decomposition The monocyclic adducts of type III and IV are not easier to prepare: compound V only could be obtained where X = NH2 and R = F, while the spirophosphorane VI was isolated when R = Ph. The experimental process involved the reaction of 2,2′-(tert-Butylazanediyl)diethanol(cas: 2160-93-2).SDS of cas: 2160-93-2

M. published an article in 1982, the title of the article was The behavior of 2,2′-(tert-butylimino)diethanol toward five-membered heterocycles containing phosphorus(III).Safety of 2,2′-(tert-Butylazanediyl)diethanol And the article contains the following content:

The reaction of 2,2′-(tert-butylimino)diethanol Me3CN(CH2CH2OH)2 (I) with dioxaphospholanes II (X = Cl, NMe2) gave III. Thermal reaction of III with I gives a complete rearrangement yielding a mixture of spirophosphorane IV, V, and traces of another product. III reacts with Ph azide to give a mixture of penta- and tetracoordinated phosphorus structures VI and VII, resp. Biacetyl condenses with III to give VIII. Reaction of dioxaphospholane IX (X = Cl) with I yields a mixture of the biphosphite V and another product believed to be either triethylammonium tris(o-phenylenedioxy) phosphate or spirobenzodioxaphospholane X. Similarly, dioxaphospholane IX (X = NMe2) reacts with I forming a mixture of XI and XII.

On April 30, 1994, Houalla, Douraid; Bounja, Zouhair; Skouta, Said; Wolf, Robert; Jaud, Joel published an article.SDS of cas: 2160-93-2 The title of the article was Macrocycles containing bicyclophosphorane moieties. And the article contained the following:

The first stable macrocycles, e.g. I (R = CMe3, Ph), containing pentacovalent phosphorus have been obtained by an Atherton-Todd reaction between the bis(hydridobicyclophosphoranes) with the corresponding binucleophile HO(CH2)2X(CH2)2OH. The tricyclic monophosphoranes II (X = O, NBu, NCMe3, NPh) as well as the noncyclic derivative III have also been isolated. A pathway that accounts for the formation of all these compounds is proposed. The x-ray crystal study of 2 16-membered rings, I (R = CMe3, Ph), confirms the diequatorial placement of the macrocyclic frame on the trigonal bipyramidal phosphorus which retains the most favorable axial-equatorial-axial annelation of the bicyclic moiety. Comparison of these 2 mol. structures points out the effect of the nature of X on the conformation of the macrocycle. The experimental process involved the reaction of 2,2′-(tert-Butylazanediyl)diethanol(cas: 2160-93-2).SDS of cas: 2160-93-2

And the article contained the following:

Alachlor, a chloroacetanilide endocrine disruptor herbicide is precarious for humans as well as the environment. Though banned by the European Union and classified as moderately hazardous by WHO, yet it is nevertheless used in several countries posing austere human and environmental health issues. Alachlor attenuation was scrutinized through simulated biodegradation experiments using soil-isolated microbes. Bio-disintegrative assays of pure three fungal and one bacterial strain; Aspergillus flavus (AF), Penicillium chrysogenum (PC), Aspergillus niger (AN) and Xanthomonas axonopodis (XA), resp. were utilized. Initial Alachlor concentration (10 mg/L) was prepared with individual microbial suspension and monitored for 35 d. Alachlor bio-transformation was analyzed quant. and qual. by gas chromatog. mass spectroscopy. XA and AN displayed maximal potential to metabolise the herbicide while forming residues; 1-chloroacetyl, 2,3- dihydro-7 ethylindole, 7 ethylindole, 7-ethyl-3-methyl-2-methoxy-2,3-dihydroindole, N- (2,6-diethylphenyl)-methyleneamine and 7-Ethyl-N-methylindole. Alachlor degradation by AF, PC, AN and XA was found to be 17.1%, 5.5%, 72.6% and 82.1%, resp., after 35 d. Microbes have displayed cometabolism as the main mechanism for Alachlor degradation This research can influence imperative and significant environmental friendly bio-remedial strategies for xenobiotic eradication.

And the article contained the following:

Triazole herbicide, Thiencarbazone-Me (TCM) applied on different crops for weedicidal activity is associated with an inherent toxicity towards bladder and urinary functionality. TCM has been first time explored for its biodegradative behavior utilizing microbes, previously isolated from soils. Simulated bio-transformation assemblies of five fungal strains; Aspergillus flavus (AF), Penicillium chrysogenum (PC), Aspergillus niger (AN), Aspergillus terrus (AT), Aspergillus fumigatus (AFu) and two bacterial strains: Xanthomonas citri (XC), Pseudomonassyringae (PS), were utilized. 10 mg/L TCM concentration was set up utilizing each microbe and analyzed for 42 days. TCM bio-degradation was evaluated by UV-Visible spectrophotometery and gas chromatog. mass spectroscopy. Aspergillus terrus (R2 = 0.86) and Penicillium chrysogenum (R2 = 0.88) exhibited highest capability to metabolize TCM while forming intermediate metabolites including; 2,4-dihydro-[1,2,4] triazol-3-one, semicarbazide and urea, Me 4-isocyanatosulfonyl-5-methylthiophene-3-carboxylate. TCM degradation by all strains AF, AFu, AN, PC, AT, PS and XC was found to be 74, 74, 81, 95, 98, 90 and 95%, resp. after 42 days elucidating the effectiveness of all the utilized strains in degrading TCM. Furthermore, present research can be extended to the optimization of the bio-deteriorative assays to be employed on the practical scale for the successful management of environment through sustainable and cost effective ways.

Huangfu, Xinlei; Wang, Yueqiao; Lu, Guozhang; Cao, Yinwei; Tang, Guo; Zhao, Yufen published an article in 2020, the title of the article was Direct synthesis of phosphorotrithioites and phosphorotrithioates from white phosphorus and thiols.Synthetic Route of 143-10-2 And the article contains the following content:

White phosphorus (P4) is still the major com. P-atom source for the production of organophosphorus compounds Conventionally, C-S-P bonds were constructed from environmentally questionable P(O)X directly or indirectly. From the green chem. point of view, formation of C-S-P bonds from inorganic mol. P4 in an easy-to-operate and atom-economical way is essential because it will avoid the hazardous chlorination process. Only five methods for the formation of C-S-P bonds from P4 have been developed over the past 70 years. Here, the first general and high-yielding synthesis of P(SR)3 and P(O)(SR)3 involving P4 and thiols is presented. With the use of KOH or K2CO3 as a base and DMSO-toluene as a solvent, both arythiols and alkylthiols are tolerant in this transformation. The reaction is characterized by a complete conversion of white phosphorus. This operationally simple and environmentally sound reaction shows a broad scope of substrates and good functional group tolerance. Moreover, this method can be easily adapted to large-scale preparation The experimental process involved the reaction of 1-Decanethiol(cas: 143-10-2).Synthetic Route of 143-10-2
