On August 31, 2022, Sakurai, Shuhei; Kawakami, Yuta; Kuroki, Manabu; Gotoh, Hiroaki published an article.Quality Control of 3-Hydroxyphenylacetic acid The title of the article was Structure-antioxidant activity (oxygen radical absorbance capacity) relationships of phenolic compounds. And the article contained the following:

Antioxidant capacity is the extent to which a compound can eliminate reactive oxygen species, and in vitro methods for its chem. evaluation have been proposed. Among these methods, the oxygen radical absorbance capacity (ORAC) assay comes close to the oxidation reaction in the living body because it generates radical species that mimic the lipid peroxyl radical involved in the peroxidation reaction of biol. components and react in a phosphate buffer. In this study, PM7, a semi-empirical MO method, was used to calculate the thermodn. properties (bond dissociation enthalpy, ionisation potential and proton affinity) associated with ORAC. We also applied the clusterwise linear regression anal. as a statistical method for grouping the antioxidants by structure. By analyzing the data for antioxidants, the trend in the hydrophilic ORAC values was determined using the calculated structures and bond dissociation enthalpies of the groups classified according to the presence or absence of oxygen functional groups in the ortho position of phenol. Further studies of indicators other than bond dissociation enthalpy are needed to predict the ORAC of other antioxidants such as flavonoids and indoles. The experimental process involved the reaction of 3-Hydroxyphenylacetic acid(cas: 621-37-4).Quality Control of 3-Hydroxyphenylacetic acid

On June 15, 2022, Namdeo, Ashutosh; Jhaveri, Jainesh H.; Mahajani, S. M.; Suresh, A. K. published an article.COA of Formula: C3H6O4 The title of the article was Palladium catalyzed liquid phase oxidation of glycerol under alkaline conditions – Kinetic analysis and modelling. And the article contained the following:

Glycerol is a major byproduct of bio-diesel production and hence its utilization has been an area of high interest in the scientific community. Oxidizing glycerol to high-value products can improve the economics of bio-diesel production In the present work, we study glycerol oxidation in alk. medium using an activated carbon supported Palladium catalyst. Kinetic studies have been performed in a batch reactor to study the effect of different parameters such as NaOH concentration, temperature, and pressure. Our results point to product inhibition by adsorbing reactant and product species. We also observe a relative insensitivity of product yields at a given conversion, to the temperature Our observations further suggest that higher NaOH concentration gives better C3 selectivity while higher oxygen pressure results in lower C3 selectivity. Based on our own studies and the literature available, the most likely kinetic pathway and a kinetic model have been proposed. Our results suggest the possibility that C-C cleavage occurs directly from the primary intermediate aldehydic species, as a result of which, carbon chain scission products (including CO2) form from very early stages of the reaction. Various strategies such as pooling temperature data to estimate rate ratios prior to full parameter estimation, use of statistical significance tests to reduce model parameters etc have been used to arrive at a minimalistic model still capable of explaining all features of the oxidation Confidence bounds on the model parameters have been estimated The experimental process involved the reaction of 2,3-Dihydroxypropanoic acid(cas: 473-81-4).COA of Formula: C3H6O4

Al-Jawad, Selma M. H.; Taha, Ali A.; Muhsen, Mustafa M. published an article in 2021, the title of the article was Study the structural, morphological and optical properties of copper sulfide prepared by two-phase colloidal method.Electric Literature of 111-29-5 And the article contains the following content:

In this paper, copper sulfide nanoparticles were synthesized by two-phase colloidal method with different reaction temperatures (140, 160, 180 and 200°C). The structural, morphol. and optical properties of prepared CuS were analyzed by the X-Ray Diffractometer (XRD), Field Emission Scanning Electron Microscope (FESEM) and UV-VIS Spectrophotometer. The XRD peaks refer to the covellite copper sulfide with hexagonal structure. FESEM showed the rod formation at lower temperatures (140 and 160°C), whereas higher temperatures (180 and 200°C) form nanocrystals within spheres structures. UV-VIS showed that CuS nanoparticles have two absorption peaks, one at UV-VIS region and the second at NIR region and its energy gap decrease with increasing of reaction temperature The experimental process involved the reaction of Pentane-1,5-diol(cas: 111-29-5).Electric Literature of 111-29-5

On August 1, 2020, Aihara, Takeshi; Miura, Hiroki; Shishido, Tetsuya published an article.Formula: C5H12O2 The title of the article was Investigation of the mechanism of the selective hydrogenolysis of C-O bonds over a Pt/WO3/Al2O3 catalyst. And the article contained the following:

The hydrogenolysis of various polyols and ethers over a Pt/WO3/Al2O3 catalyst was investigated. The hydrogenolysis rate of a C-O bond at a secondary carbon was higher than that at a primary carbon, indicating that a hydroxyl (OH) group at a primary carbon played an important role in the dissociation of a C-O bond. Moreover, the dissociation position of the C-O bond in alcs. and ethers strongly depended on the stability of the carbocation intermediate, and hydrogenolysis via a secondary carbocation as an intermediate proceeded preferentially to that via a primary carbocation. The kinetics of the hydrogenolysis of C3 polyols were also investigated. The reaction orders with respect to the concentrations of glycerol, 1,2- and 1,3-propanediol were almost the same. In contrast, different reaction orders with respect to the H2 pressure were observed for the hydrogenolysis of C3 polyols with or without vicinal OH groups, indicating that the dissociation of a C-O bond at primary and secondary carbons proceeded via completely different mechanisms. These investigations suggested that both the structure and position of a substrate on the catalyst surface must be controlled for highly selective hydrogenolysis. The experimental process involved the reaction of Pentane-1,5-diol(cas: 111-29-5).Formula: C5H12O2
