One of the major reasons for studying chemical kinetics is to use measurements of the macroscopic properties of a system, category: Tetrahydrofurans, such as the rate of change in the concentration of reactants or products with time.In a article, mentioned the application of 5455-94-7, Name is 2,2,5,5-Tetramethyldihydrofuran-3(2H)-one, molecular formula is C8H14O2

Specific solvation effects on stereoselectivity in the reduction of a cyclohexanone by lithium aluminum tri-t-butoxyhydride have been studied by adding measured quantities of diethyl ether, tetrahydrofuran (THF) and methyl-substituted tetrahydrofurans to benzene solvent, and various amounts of THF to diethyl ether solvent. A steric hindrance effect in the case of bulky addends was observed, and a significant increase in stereoselectivity for less bulky addends was found. The results have been explained in terms of complexing, or steric hindrance to complexing, of the lithium cation.

Electric Literature of 2144-40-3, Because a catalyst decreases the height of the energy barrier, its presence increases the reaction rates of both the forward and the reverse reactions by the same amount.2144-40-3, Name is (cis-Tetrahydrofuran-2,5-diyl)dimethanol, molecular formula is C6H12O3.

Effective encapsulation strategies are highly sought-after in heterogeneous catalysis for preparing highly active and stable metal (oxide) nanocatalysts. Herein, we report an optimized Melt Infiltration (MI) procedure to confine nickel(oxide) nanoparticles (NPs) into hierarchical microporous-mesoporous scaffolds. Three SBA-15 silicas were synthesized in order to obtain different degrees of interconnectivity between the main mesopores. The impact of the SBA-15 pore characteristics, i.e., this interconnectivity, also named secondary intra-wall porosity (IWP), on the final nickel (oxide) NPs size and localization has been specifically investigated. Using MI, which consisted in the diffusion of the precursor in the liquid state inside the porosity of the support in the presence of the native surfactant occluding the pores, a selective localization of the NiO NPs inside the IWP was obtained, without large NPs plugging the main mesopores if IWP pores connecting the main mesopores do exist. When IWP ? selective localization ? occurs for the NPs, they show a size directly depending on the IWP dimensions. The obtained materials were tested, after reduction, in the hydrogenation reactions of cinnamaldehyde and 5-hydroxymethylfurfural. The catalytic results underline the positive effect of IWP – confinement of NPs to obtain and maintain an elevated dispersion of the metallic Ni active phase and to reach a high catalytic activity in hydrogenation under mild reaction conditions.

In heterogeneous catalysis, the catalyst is in a different phase from the reactants. category: Tetrahydrofurans, At least one of the reactants interacts with the solid surface in a physical process called adsorption in such a way. 7331-52-4, name is (S)-4-Hydroxydihydrofuran-2(3H)-one. In an article，Which mentioned a new discovery about 7331-52-4

High concentrations of the acid-insoluble residue (AIR, also known as “Klason lignin”) in decomposing litter are considered to indicate high resistance to decomposition; however, the chemical composition of AIR in different types of litter and soil organic matter is poorly understood. In the present study, we characterized samples of common litter (L) types in boreal forests (needle, coarse tree, and moss), as well as fragmented litter (F), and humus (H) layers in two south boreal forest sites using a combination of sequential fractionation and pyrolysis-GC-MS. The results showed that the unfractionated samples were composed of cellulose-derived carbohydrates, guaiacyl-type lignin and other polyphenolic compounds, and that there was little variation among samples. However, pyrolysis-GC-MS analyses of AIR demonstrated that the composition of the AIR fraction differed among the analyzed litter materials as well as between the layers in the soil organic horizon. In the F and H layers, the AIR fraction contained guaiacyl-type lignin and other polyphenolics, as well as lipophilic compounds, which were indicated by the pyrolysis product methyldehydroabietate and short-chain fatty acids. In the AIR fraction, only small amounts of carbohydrate-derived compounds were detected, confirming that the sequential fractionation method efficiently removes soluble polysaccharides. The AIR fraction was poorly soluble in all solvents. The results presented here confirm that the sequential fractionation method efficiently separates water-, chloroform-, and acid-soluble (72% H2SO4) compounds from acid-insoluble compounds (AIR). However, AIR was shown to be a mixture of polyphenolic (mainly lignin-derived) and lipophilic (including fatty acids and resin acid) structures, and may therefore be a poor indicator of lignin and phenolic compounds when investigating the F and H layers in the organic horizon.

I hope this article can help some friends in scientific research. I am very proud of our efforts over the past few months and hope to 7331-52-4, help many people in the next few years.category: Tetrahydrofurans

This study aimed to assess the effect of fermentation time and potato pulp addition on the fermentation characteristics of dough and textural profiles of the steamed bread. Volatile compounds in steamed bread processing were also determined. Rheofermentometer analysis showed that the gas retention capability of dough decreased with the increase in potato pulp level, and the productive fermentation time might be shortened through the addition of high potato pulp levels (40%?50%) to dough. The resistance to extension of dough samples decreased with the increase in fermentation time and potato pulp level. When the fermentation time was 60?75 min, all steamed bread samples had high specific volumes and soft textures. Moreover, the volatile compounds in the fermented dough and steamed bread were enriched by the addition of potato pulp. These results indicated that fermentation time and potato pulp affected the technological properties and volatile compounds of wheat dough and steamed bread.
