Synthesis of PtSn nanoparticles on carbon materials by different preparation methods for selective catalytic hydrogenation of citral was written by Stassi, Julieta;Mendez, Jonathan;Vilella, Irene;De Miguel, Sergio;Zgolicz, Patricia. And the article was included in Chemical Engineering Communications in 2020.Recommanded Product: 3,7-Dimethyloctan-1-ol The following contents are mentioned in the article:

In this work, PtSn bimetallic catalysts supported on three different carbons were prepared by two methods: (a) conventional impregnation followed by a reduction treatment under H_2- flow (CI) and (b) deposition-reduction in liquid phase (RLP). All the catalysts were tested in the selective hydrogenation of citral to the unsaturated alcs. (UA). A strong influence of the preparation method and the support was found over the selectivity to UA. For CI prepared catalysts, low Sn loadings give a metallic phase with highly ordered PtSn alloys, while for RLP catalysts, high Sn loadings give highly ordered phases with Sn ionic species intercalated in the Pt metallic phase. Both ordered phases are highly effective to promote the hydrogenation of carbonyl group. For the RLP method, high Sn/Pt molar ratios in solution leads to the formation of PtSn complexes with a good interaction between metals. This study involved multiple reactions and reactants, such as 3,7-Dimethyloctan-1-ol (cas: 106-21-8Recommanded Product: 3,7-Dimethyloctan-1-ol).

3,7-Dimethyloctan-1-ol (cas: 106-21-8) belongs to alcohols. Because alcohols are easily synthesized and easily transformed into other compounds, they serve as important intermediates in organic synthesis. 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.Recommanded Product: 3,7-Dimethyloctan-1-ol

Effects of high pressure in combination with the type of aging on the eating quality and biochemical changes in pork loin was written by Hwang, Su-In;Hong, Geun-Pyo. And the article was included in Meat Science in 2020.COA of Formula: C10H22O The following contents are mentioned in the article:

This study investigated the effects of high pressure (0.1, 150 and 400 MPa) and the aging method (wet- and dry-aging) on the quality characteristics of pork loin. Pork pressurized at the target pressure levels was aged at 1°C for 3 wk in vacuum packaging (wet-aging) or a moisture/vapor permeable bag (dry-aging). The water binding properties, shear force, color, volatile compounds and microbial counts were estimated as the quality characteristics of aged pork. Despite dry-aged pork having distinctive flavor characteristics, high moisture loss during aging was estimated as the most important factor that affected the quality of aged pork. Alternately, wet aging showed advantages of producing tender and juicy pork, and moderate pressurization (150 MPa) modified or improved the qualities of wet-aged pork. Consequently, this study indicated that pressurization followed by wet-aging had potential application as a meat tenderizing technique. This study involved multiple reactions and reactants, such as 3,7-Dimethyloctan-1-ol (cas: 106-21-8COA of Formula: C10H22O).

3,7-Dimethyloctan-1-ol (cas: 106-21-8) belongs to alcohols. The oxygen atom of the strongly polarized O―H bond of an alcohol pulls electron density away from the hydrogen atom. This polarized hydrogen, which bears a partial positive charge, can form a hydrogen bond with a pair of nonbonding electrons on another oxygen atom. Grignard and organolithium reagents are powerful tools for organic synthesis, and the most common products of their reactions are alcohols.COA of Formula: C10H22O

Effect of high hydrostatic pressure on pasting properties, volatile flavor components, and water distribution of cooked black rice was written by Meng, Ling;Zhang, Wencheng;Hui, Ailing;Wu, Zeyu. And the article was included in Journal of Food Processing and Preservation in 2020.Category: alcohols-buliding-blocks The following contents are mentioned in the article:

The effect of high hydrostatic pressure (HHP) on pasting properties, volatile flavor components, and water distribution of cooked black rice (BR) was investigated. BR samples were subjected to HHP treatments at 200, 300, 400, and 500 MPa for 15 min, and then cooked for further evaluation. Results showed that HHP-treated samples exhibited lower viscosity compared to the control group, with the lowest value at 500 MPa. Among 126 flavor compounds identified in cooked BR stored for 7 days, the total contents of three key flavor components (alcs., ketones, and aldehydes) were greatly enhanced, indicating that HHP contributed to the aroma quality of cooked BR. Water characteristics were determined by low-field NMR (LF-NMR), and three water fractions were detected and identified as T21, T22, and T23. The value of T21 gradually decreased with the increase of pressure, suggesting that HHP reduced the retrogradation degree of cooked BR. This study involved multiple reactions and reactants, such as 3,7-Dimethyloctan-1-ol (cas: 106-21-8Category: alcohols-buliding-blocks).

3,7-Dimethyloctan-1-ol (cas: 106-21-8) belongs to alcohols. The oxygen atom of the strongly polarized O―H bond of an alcohol pulls electron density away from the hydrogen atom.

Apparent properties of waterborne polyurethane emulsion was written by Ma, De-rong;Hu, Zheng-shui. And the article was included in Qingdao Keji Daxue Xuebao, Ziran Kexueban in 2013.Quality Control of 2-Butyl-2-ethylpropane-1,3-diol The following contents are mentioned in the article:

A high solid-containing waterborne polyurethane emulsion was prepared using IPDI, polyester polyol and dimethylolbutyric acid (DMBA) by self-emulsification method. Effects of emulsification temperature, small mol. diol and chain extender on emulsion viscosity, particle size and colloid morphol. were investigated. The results showed that the solid content of emulsion with low viscosity and good stability could reach 45% when DMBA mass fraction was 5.5% and emulsification temperature was 2°C. By adding 2-butyl-2-ethyl-1, 3-propanediol (BEPD) or chain extender isophorone diamine (IPDA), the particle size became smaller and the emulsion viscosity became lower by adjustment of intermol. interaction. Moreover, emulsion stability could be improved by using non-ionic hydrophilic chain extender trimethylolpropane polyethylene glycol monomethyl ether (TMPEG) which could shield the micelle electrostatic repulsion by means of synergy.

On the nitroxide mediated polymerization of methacrylates derived from bio-sourced terpenes in miniemulsion, a step towards sustainable products was written by Noppalit, Sayrung;Simula, Alexandre;Billon, Laurent;Asua, Jose M.. And the article was included in Polymer Chemistry in 2020.Formula: C10H22O The following contents are mentioned in the article:

The incorporation of monomers derived from natural resources into industrially viable block copolymers is a long-standing problem that has not been appropriately solved yet due to a combination of issues that include the use of toxic solvents, relatively expensive control agents, and the need of intermediate purification steps. This study aims at overcoming these limitations. Nitroxide mediated polymerization of methacrylates synthesized from bio-resourced terpenes is carried out in miniemulsion using Dispolreg 007, an alkoxyamine that is produced through a cost effective and easily scalable synthetic route. Well-defined poly(tetrahydrogeraniol methacrylate)-b-poly(cyclademol methacrylate) diblock copolymers are obtained at high monomer conversions (>90%), without the need for intermediate purification steps. The resulting “soft”/”hard” diblock copolymers show good potential as waterborne pressure-sensitive adhesives. This study involved multiple reactions and reactants, such as 3,7-Dimethyloctan-1-ol (cas: 106-21-8Formula: C10H22O).

Pd^II-Catalyzed Site-selective β- and γ-C(sp³)-H Arylation of Primary Aldehydes Controlled by Transient Directing Groups was written by Li, Yi-Hao;Ouyang, Yuxin;Chekshin, Nikita;Yu, Jin-Quan. And the article was included in Journal of the American Chemical Society in 2022.Electric Literature of C10H22O The following contents are mentioned in the article:

Pd(II)-catalyzed site-selective β- and γ-C(sp³)-H arylation of primary aldehydes C(R)(R¹)(R²)CH₂CHO (R = Me, cyclohexylmethyl, 2,2-dimethylpropyl, etc.; R¹ = H, Me; R² = H, Me) and 2-cyclohexylacetaldehyde is developed by rational design of L,X-type transient directing groups (TDG). External 2-pyridone ligands such as (5-nitro-3-(trifluoromethyl)-2(1H)-pyridinone) are identified to be crucial for the observed reactivity. By minimizing the loading of acid additives, the ligand effect is enhanced to achieve high reactivities of the challenging primary aldehyde substrates. Site selectivity can be switched from the proximate to the relatively remote position by changing the bite angle of TDG to match the desired palladacycle size. Exptl. and computational investigations support this rationale for designing TDG to potentially achieve remote site-selective C(sp³)-H functionalizations. This study involved multiple reactions and reactants, such as 3,7-Dimethyloctan-1-ol (cas: 106-21-8Electric Literature of C10H22O).

3,7-Dimethyloctan-1-ol (cas: 106-21-8) belongs to alcohols. A strong base can deprotonate an alcohol to yield an alkoxide ion (R―O−). For example, sodamide (NaNH2), a very strong base, abstracts the hydrogen atom of an alcohol. Alcohols may be oxidized to give ketones, aldehydes, and carboxylic acids. These functional groups are useful for further reactions. Oxidation of organic compounds generally increases the number of bonds from carbon to oxygen (or another electronegative element, such as a halogen), and it may decrease the number of bonds to hydrogen.Electric Literature of C10H22O
