The quality characteristics and stability of phenolic byproducts from Cola nitida wastes are critical factors for drug formulation and food nutraceutical applications. In this study, the effect of electromagnetic-based microwave-reflux extraction on the total phenolic content, antioxidant capacity, morphol. characteristics, physisorption and chromatog. phenolic profiles were successfully investigated. These physicochem. analyses are often employed in the standardisation of dried herbal and food nutraceutical products. In this study, the electromagnetic-based extraction process was optimized using the Box-Behnken design. The oleoresin bio-products were subsequently characterised to determine the total phenolic content, morphol. and microstructural degradation These analyses were conducted to elucidate the effect of the microwave heating on the C. nitida pod powder. From the predicted response, the optimal percentage yield was achieved at 26.20% under 5.39 min of irradiation time, 440 W microwave power and oven temperature of 55掳C. Moreover, the rapid estimation of the phenolic content and antioxidant capacity were recorded at 124.84 卤 0.064 mg gallic acid equivalent (GAE)/g dry weight (d.w.) and 6.93 卤 0.34渭g/mL, resp. The physicochem. characterization results from the Fourier-transform IR spectroscopy, field emission SEM and physisorption analyses showed remarkable changes in the micro-surface area (13.66%) characteristics. The recorded optimal conditions established a basis for future scale-up of microwave extraction parameters with a potential for maximum yield. The physiochem. characterization revealed the functional characteristics of C. nitida and their tolerance to microwave heating. In the experiment, the researchers used many compounds, for example, (E)-4-(3,5-Dihydroxystyryl)benzene-1,2-diol (cas: 10083-24-6HPLC of Formula: 10083-24-6).

(E)-4-(3,5-Dihydroxystyryl)benzene-1,2-diol (cas: 10083-24-6) belongs to alcohols. Alkyl halides are often synthesized from alcohols, in effect substituting a halogen atom for the hydroxyl group. A multistep synthesis may use Grignard-like reactions to form an alcohol with the desired carbon structure, followed by reactions to convert the hydroxyl group of the alcohol to the desired functionality.HPLC of Formula: 10083-24-6

Imidazolium ion tethered TsDPENs as efficient water-soluble ligands for rhodium catalyzed asymmetric transfer hydrogenation of aromatic ketones was written by Kang, Guowei;Lin, Silong;Shiwakoti, Atul;Ni, Bukuo. And the article was included in Catalysis Communications in 2014.Category: alcohols-buliding-blocks This article mentions the following:

An imidazolium ion tethered TsDPEN has been synthesized readily and used as a water-soluble ligand for [Cp*RhCl₂]₂ catalyzed asym. transfer hydrogenation (ATH) of aromatic ketones in water. This process provided secondary alcs. in moderate to excellent conversions (up to 100%) with high enantioselectivity (up to 98% ee) under mild reaction conditions without adding any surfactants. The catalytic system is highly effective with the substrate to catalyst (S/C) ratio of 500 and low hydride donor loading of 1.5 equivalent of HCO₂Na. The procedure presented is simple and makes this method suitable for practical use. The synthesis of the target compounds was achieved using [[[[[(amino)diphenylethyl]amino]sulfonyl]phenyl]methyl]imidazolium salt and a rhodium complex as catalyst combination. The catalyst was prepared using N-[(1S,2S)-2-amino-1,2-diphenylethyl]carbamic acid 1,1-dimethylethyl ester and imidazole derivatives as starting materials. Under optimized conditions di-渭-(chloro)dichlorobis[(1,2,3,4,5-畏)-1,2,3,4,5-pentamethyl-2,4-cyclopentadien-1-yl]dirhodium was used as a catalyst. Transfer hydrogenation of 1-(phenyl)ethanone (acetophenone) derivatives gave (伪S)-伪-(methyl)benzenemethanol (chiral benzyl alc.) derivatives In the experiment, the researchers used many compounds, for example, (S)-1-(2-Fluorophenyl)ethanol (cas: 171032-87-4Category: alcohols-buliding-blocks).

(S)-1-(2-Fluorophenyl)ethanol (cas: 171032-87-4) belongs to alcohols. A strong base can deprotonate an alcohol to yield an alkoxide ion (R鈥昈鈭?.

And the article was included in LWT–Food Science and Technology in 2022.SDS of cas: 149-32-6 This article mentions the following:

To investigate the effects of inoculating Leuconostoc mesenteroides or Lactiplantibacillus plantarum on the changes in metabolites in Pleurotus eryngii Jiaosu, a fermented plant extract rich in nutrients and bioactive compounds, the physicochem. and metabolite features of the treated Jiaosu were compared to those of spontaneously-fermented Jiaosu. The physicochem. features of Jiaosu fermented with Leuconostoc mesenteroides or Lactiplantibacillus plantarum were superior to spontaneously-fermented Jiaosu. An Partial Least Squares Discrimination Anal. (PLS-DA) score plot showed a clear difference in metabolites between spontaneous fermentation group (SFG) and inoculated Lactiplantibacillus plantarum group (LPG). Metabolites were remarkably different between LPG and SFG on the first day of fermentation The differential metabolites included sugars, acids and alcs. This study highlights the applicability of GC-MS based metabolomics as a tool to monitor Jiaosu fermentation In the experiment, the researchers used many compounds, for example, (2R,3S)-rel-Butane-1,2,3,4-tetraol (cas: 149-32-6SDS of cas: 149-32-6).

(2R,3S)-rel-Butane-1,2,3,4-tetraol (cas: 149-32-6) belongs to alcohols. Under appropriate conditions, inorganic acids also react with alcohols to form esters. To form these esters, a wide variety of specialized reagents and conditions can be used. Under carefully controlled conditions, simple alcohols can undergo intermolecular dehydration to give ethers.

Do not forget the classical catalyst poisons: The case of biomass to glycols via catalytic hydrogenolysis was written by te Molder, Thimo D. J.;Kersten, Sascha R. A.;Lange, Jean-Paul;Ruiz, M. Pilar. And the article was included in Biofuels, Bioproducts & Biorefining in 2022.Related Products of 57-55-6 This article mentions the following:

The conversion of herbaceous biomass to glycols via tungstate catalyzed hydrogenolysis is challenging owing to its high content of extractives, inorganics and S/N, compared with woody biomass. We tested the hydrogenolysis performance of hay in batch autoclave experiments in the presence of soluble sodium polytungstate and Raney Ni at 245掳C, both in excess of catalyst as well as under catalyst-starving conditions. By this method, we found that addnl. tungstate and Raney Ni poisons, or at least their much higher concentrations, are present in the hay feedstock compared with woody biomass. It turns out that N- and in particular S-containing components present in hay are the root cause for deactivation of the hydrogenation catalyst. From the exptl. data we have derived feedstock criteria for N and S that should be targeted in terms of catalyst consumption for operation in an industrially relevant window. These challenging criteria urge the development of effective pretreatments for S/N removal or the employment of S/N-tolerant catalysts in the field of catalytic biomass conversion. In the experiment, the researchers used many compounds, for example, 1,2-Propanediol (cas: 57-55-6Related Products of 57-55-6).

1,2-Propanediol (cas: 57-55-6) belongs to alcohols. Similar to water, an alcohol can be pictured as having an sp3 hybridized tetrahedral oxygen atom with nonbonding pairs of electrons occupying two of the four sp3 hybrid orbitals. A multistep synthesis may use Grignard-like reactions to form an alcohol with the desired carbon structure, followed by reactions to convert the hydroxyl group of the alcohol to the desired functionality.Related Products of 57-55-6

Light-Responsive, Shape-Switchable Block Copolymer Particles was written by Lee, Junhyuk;Ku, Kang Hee;Kim, Jinwoo;Lee, Young Jun;Jang, Se Gyu;Kim, Bumjoon J.. And the article was included in Journal of the American Chemical Society in 2019.Application of 60463-12-9 This article mentions the following:

A robust strategy is developed for preparing light-responsive block copolymer (BCP) particles in which shape and color can be actively controlled with high spatial and temporal resolution The key to achieving light-responsive shape transitions of BCP particles is the design and synthesis of surfactants containing light-active groups (i.e., nitrobenzyl esters and coumarin esters) that modulate the amphiphilicity and interfacial activity of the surfactants in response to light of a specific wavelength. These light-induced changes in surfactant structure modify the surface and wetting properties of BCP particles, affording both shape and morphol. transitions of the particles, for example from spheres with an onion-like inner morphol. to prolate or oblate ellipsoids with axially stacked nanostructures. In particular, wavelength-selective shape transformation of the BCP particles can be achieved with a mixture of two light-active surfactants that respond to different wavelengths of light (i.e., 254 and 420 nm). Through the use of light-emitting, photoresponsive surfactants, light-induced changes in both color and shape are further demonstrated. Finally, to demonstrate the potential of the light-triggered shape control of BCP particles in patterning features with microscale resolution, the shape-switchable BCP particles are successfully integrated into a patterned, free-standing hydrogel film, which can be used as a portable, high-resolution display. In the experiment, the researchers used many compounds, for example, 3-(Hydroxymethyl)-4-nitrophenol (cas: 60463-12-9Application of 60463-12-9).

3-(Hydroxymethyl)-4-nitrophenol (cas: 60463-12-9) belongs to alcohols. Similar to water, an alcohol can be pictured as having an sp3 hybridized tetrahedral oxygen atom with nonbonding pairs of electrons occupying two of the four sp3 hybrid orbitals. Converting an alcohol to an alkene requires removal of the hydroxyl group and a hydrogen atom on the neighbouring carbon atom. Dehydrations are most commonly carried out by warming the alcohol in the presence of a strong dehydrating acid, such as concentrated sulfuric acid.Application of 60463-12-9

Some high-potential trithioether chelates of copper was written by Kanters, Rene P. F.;Yu, Ru;Addison, Anthony W.. And the article was included in Inorganica Chimica Acta in 1992.SDS of cas: 1122-71-0 This article mentions the following:

The linear quadridentate ligand 1,8-bis(2′-quinolyl)-3,6-dithiaoctane and the 3 quinquedentate ligands 1,9-bis(2′-pyridyl)-2,5,8-trithianonane, 1,9-bis(6′-methyl-2′-pyridyl)-2,5,8-trithianonane and 1,11-bis(2′-quinolyl)-3,6,9-trithiaundecane were prepared The deep green-blue Cu(II) chelates were characterized by optical and ESR spectroscopy and cyclic voltammetry. The 2 pyridyl chelates had similar tetragonal coordination about the Cu, with an equatorial N₂S₂ donor set, plus the 3rd thioether S bound axially. The most marked consequence of the pyridine 伪-methylation was that the Cu²⁺/⁺ reduction potential was raised by 鈭?00 mV; otherwise, the E_1/2 was consonant with previously advanced models for correlating redox potentials with ligand structural features. The pyridyl Cu(II) complexes were isolated as the tetrafluoroborate salts, whereas the quinolyl-Cu(II) chelates were rather redox unstable, in association with even more pos. Cu²⁺/⁺聽E_1/2 values, similar to that for dibromine reduction In the experiment, the researchers used many compounds, for example, 6-Methyl-2-pyridinemethanol (cas: 1122-71-0SDS of cas: 1122-71-0).
