On June 30, 2021, Shao, Yuewen; Wang, Junzhe; Sun, Kai; Gao, Guoming; Li, Chao; Zhang, Lijun; Zhang, Shu; Xu, Leilei; Hu, Guangzhi; Hu, Xun published an article.Application of 111-29-5 The title of the article was Selective hydrogenation of furfural and its derivative over bimetallic NiFe-based catalysts: Understanding the synergy between Ni sites and Ni-Fe alloy. And the article contained the following:

Pentanediols (1,2-pentanediol and 1,5-pentanediol) are important feedstock for synthesis of fine chems., production of which from the biomass-derived furfural or furfuryl alc. (FA) has been considered as a sustainable route and attracted much interest. In this study, the catalysts with Ni-Fe as the metal sites and Mg-Al layered double hydroxides (LDH) as precursor of support were synthesized. The results showed that the presence of Fe in catalyst affected both the development of the pores of the catalyst and the catalytic behaviors of nickel species. A low Fe content facilitated formation of mesoporous structure, but the higher content destroyed the LDH structure, resulting in a decreased surface area. Fe could also react with metallic Ni to form NiFe alloy. This decreased the catalytic activity for the further hydrogenation of the furan ring in FA, and FA would thus have the chance to produce pentanediols via hydrogenolysis. The in-situ diffuse reflectance IR Fourier transform spectroscopy characterization of hydrogenation of FA indicated that the alloying between Fe and Ni resulted in a weak adsorption of C=C group in furan ring and moderate adsorption of C-O-C group, which suppressed the complete hydrogenation of FA while facilitated the ring-opening of FA to form the pentanediols. The experimental process involved the reaction of Pentane-1,5-diol(cas: 111-29-5).Application of 111-29-5

On September 15, 2021, Xiong, Junping; Zhang, Dejin; Yang, Guoqiang; Zhang, Zhibing published an article.Computed Properties of 96-76-4 The title of the article was Alkylation of Phenol and tert-Butyl Alcohol Catalyzed by Deep Eutectic Solvents under Mild Conditions. And the article contained the following:

Tert-Bu phenol is an important intermediate for organic synthesis and the preparation of tert-Bu phenol under mild conditions is of great significance. In our work, five kinds of deep eutectic solvents were synthesized to catalyze the alkylation of phenol and tert-Bu alc. The deep eutectic solvent consisting of choline bisulfate (ChBf) and p-toluene sulfonic acid (p-TsOH) was proved to be a better catalyst. By employing the response surface methodol. to optimize the reaction conditions, we found that 99.5% conversion of tert-Bu alc. was obtained at a reaction temperature of 30°C. The temperature of alkylation reaction was much milder than those in previous reports. The kinetic model for this reaction was established based on the Runge-Kutta-Fehlberg method and the recycle performance for the catalyst was evaluated. Excellent conversion of tert-Bu alc. can be obtained after recycling eight times. This method provides a potential route for the synthesis of tert-Bu phenol under mild conditions in industry. The experimental process involved the reaction of 2,4-Di-tert-butylphenol(cas: 96-76-4).Computed Properties of 96-76-4

On April 1, 2021, Yong, Yang; Gu, Huajun; Zhang, Qingxiao; Fang, Zhang; Hui, Li published an article.Application In Synthesis of SweetPearlR P300 DC Maltitol The title of the article was Hollow ni-p amorphous alloy nanospheres: An efficient catalyst for sugars hydrogenation to polyols. And the article contained the following:

In this paper, hollow Ni – P nanospheres (NSs) are prepared through Ni electroless plating on the Au-activated silica NSs externally covered by aminopropyl moieties, followed by removing the silica template with sodium hydroxide. With various characterizations, the resulting hollow Ni – P NSs are identified to be amorphous alloy. During liquid-phase hydrogenation of sugars to sugar alcs., the hollow Ni – P amorphous alloy NSs delivered much superior catalytic performances to the com. Raney Ni catalyst, showing a good potential in practical applications. Of particular interest is the unique hollow chamber structure of the hollow Ni – P amorphous alloy NSs, which allows for improving catalytic activity and durability relative to those associated with the dense Ni – P amorphous alloy NSs. This work demonstrated that such hollow Ni materials with nanoporous chamber structure displayed advantages such as easy exptl. handling and high accessibility for the reactants in liquid-phase reaction, more Ni active sites, as well as the existence of more electron-enriched inner surface, which is essential to provide highly efficient catalysts for some reactions.

On August 31, 2019, Sekerova, Lada; Spacilova, Marketa; Vyskocilova, Eliska; Krupka, Jiri; Cerveny, Libor published an article.Computed Properties of 78-26-2 The title of the article was Acid catalyzed acetalization of aldehydes with diols resulting into the formation of fragrant cyclic acetals. And the article contained the following:

The influence of reaction conditions (amount and type of the catalyst, the reaction temperature, the type of the solvent) on the reaction course of the acetalization of aldehydes with diols was tested in this paper. The optimization of reaction conditions was performed on model reaction, acetalization of 2-methylpentanal by 2-methyl-2-propyl-1,3-propanediol leading to the formation of fragrant compound 2-(1-methylbutyl)-5-methyl-5-propyl-1,3-dioxane (Troenan). Para toluenesulfonic acid was used as an active homogeneous catalyst. It appeared to be advantageous not to use any solvent in the reaction. Using 0.3 wt% of the catalyst the almost total conversion of 2-methylpentanal was achieved after 240 min of reaction at room temperature while the selectivity to the desired product was about 98%. The optimized reaction conditions were applied to the preparation of four cyclic fragrant acetals (namely 2-hexyl-1,3-dioxolane, 2-hexyl-4-methyl-1,3-dioxolane, 2-benzyl-5-hydroxy-1,3-dioxane and 2-(1-methylbutyl)-5-methyl-5-propyl-1,3-dioxane) in larger scale; and these were sensory evaluated after purification step. Prepared heterogeneous catalysts, acid modified montmorillonite (MMT) K-10 (treated by H2SO4, HNO3, and HCl) were successful in the model reaction. The conversion of 2-methylpentanal over 90% was achieved using acid modified MMT after 300 min of reaction at room temperature, the selectivity to the desired product was about 98%. MMT/H2SO4 can be used in the model reaction four times without any change in the reaction course, what makes it promising for the further application. The experimental process involved the reaction of 2-Methyl-2-propylpropane-1,3-diol(cas: 78-26-2).Computed Properties of 78-26-2

Bretzler, Patrick; Huber, Michael; Nickl, Simon; Koehler, Klaus published an article in 2020, the title of the article was Hydrogenation of furfural by noble metal-free nickel modified tungsten carbide catalysts.Name: Pentane-1,5-diol And the article contains the following content:

Nickel-tungsten carbide catalysts convert furfural to high value products in a liquid phase catalytic reaction. The product distribution depends on the solvent and the Ni-W-ratio of the catalyst. In iso-Pr alc. a combination of Ni and WxC enables the opening of the furan ring to yield 1,2-pentanediol. Nickel accelerates the tungsten oxide reduction in the tungsten carbide catalyst synthesis and facilitates the carbon insertion. Nickel modified tungsten carbide is a promising, noble metal-free catalyst system for the upgrading of furfural based renewable resources. Its preparation is facilitated compared to unmodified tungsten carbide catalysts. The experimental process involved the reaction of Pentane-1,5-diol(cas: 111-29-5).Name: Pentane-1,5-diol

On November 15, 2022, Li, Jianmei; Yang, Ruofeng; Xu, Shuguang; Zhou, Cuiqing; Xiao, Yuan; Hu, Changwei; Tsang, Daniel C. W. published an article.Recommanded Product: 473-81-4 The title of the article was Biomass-derived polyols valorization towards glycolic acid production with high atom-economy. And the article contained the following:

Taking advantage of the inherent structure in biomass for attractive chem. synthesis with high atom economy is vital for a sustainable future but remains a great challenge. Herein, we discovered a new route for glycolic acid (GcA) synthesis using various biomass-derived polyols as feedstock with an exceptionally high atom utilization (~93%). Up to ~90 C-mol% yield of GcA could be achieved, representing the highest value among the state-of-the-art biomass valorization strategies. Strongly certified by in situ exptl. tests and multi-scale theor. calculations, it was identified that dynamical accommodation of the flexible unsaturated dangling-like Cucus-O bond in Cu2O(111) to polyols drove electron transfer from polyols to Cucus, enabling the precise activation of C1-H and C2-C3 bonds. These contributions accomplished the complex cascade reactions in polyol transformation throughout chain-sugar as intermediate with notable conformation superiority, thus generating GcA selectively.

On January 31, 2022, Vo, Truong-Giang; Ho, Po-Yun; Chiang, Chia-Ying published an article.Name: 2,3-Dihydroxypropanoic acid The title of the article was Operando mechanistic studies of selective oxidation of glycerol to dihydroxyacetone over amorphous cobalt oxide. And the article contained the following:

In this work, cobalt oxide (CoOx) has been demonstrated as an efficient and selective electrocatalyst for producing value-added dihydroxyacetone (DHA) from industrial byproduct glycerol. Under optimized conditions, DHA with high selectivity up to 45% and a high production rate of 9.6μmol h-1 cm-2 is obtained at high c.d. over 3 mA cm-2 without the occurrence of the oxygen evolution reaction. Operando Raman spectroscopy features the potential-induced structural transformation between CoOx and oxyhydroxides from which a correlation among applied potential, surface chem. of electrocatalyst, and product distribution are built. These results point toward the viability of using inexpensive materials for electrochem. biomass upgrading as well as providing opportunities for studying structural evolution and activity origin of catalysts under realistic working conditions that can be widely extended to most electrocatalytic biomass valorization processes.

On September 15, 2022, Sadier, Achraf; Paul, Sebastien; Marceau, Eric; Wojcieszak, Robert published an article.Application In Synthesis of SweetPearlR P300 DC Maltitol The title of the article was Ni-Fe alloying enhances the efficiency of the maltose hydrogenation process: The role of surface species and kinetic study. And the article contained the following:

Unlike the conversion of monosaccharides to the corresponding polyols, the production of maltitol by hydrogenation of maltose has been seldom investigated in the literature, despite its industrial importance. Monometallic Ni catalysts are known for their lack of stability, and the objective of the present paper is to determine through a kinetic study, to what extent a Ni-Fe/SiO2 bimetallic catalyst would outperform a Ni/SiO2 catalyst in the aqueous phase hydrogenation of maltose. The effect of reaction parameters (T = 80-150°C, PH2 = 20-40 bar, maltose mass fraction in water = 4.4-17.5 wt%) on activity, selectivity, and stability was examined In all cases, maltitol was the major product, with a carbon balance higher than 98%, but maltose hydrolysis to glucose occurred in the upper range of temperature In order to preserve both the catalyst selectivity and stability, a temperature of 80°C was selected for the kinetic study. The adsorption constant of maltose and the apparent hydrogenation rate constant for the Ni-Fe catalyst were both larger by a factor 2-3 compared with the Ni catalyst, indicating a stronger interaction of maltose with the Ni-Fe surface. Another major difference was a reaction order of 0.5 with respect to the hydrogen pressure on Ni-Fe/SiO2 compared with a near zero-order on Ni/SiO2. The activity of the Ni-Fe catalyst remained constant for three runs of reaction without major structural changes, while the Ni catalyst deactivated by transforming to a phyllosilicate phase. The experimental process involved the reaction of SweetPearlR P300 DC Maltitol(cas: 585-88-6).Application In Synthesis of SweetPearlR P300 DC Maltitol

On April 30, 2020, Li, Xuemei; Tian, Junying; Liu, Hailong; Tang, Congkui; Xia, Chungu; Chen, Jing; Huang, Zhiwei published an article.Computed Properties of 111-29-5 The title of the article was Effective synthesis of 5-amino-1-pentanol by reductive amination of biomass-derived 2-hydroxytetrahydropyran over supported Ni catalysts. And the article contained the following:

A highly efficient and green process was developed for the synthesis of useful 5-amino-1-pentanol (5-AP) from biomass-derived dihydropyran by coupling the in situ generation of 5-hydroxypentanal (5-HP, via the ring-opening tautomerization of 2-hydroxytetrahydropyran (2-HTHP)) and its reductive amination over supported Ni catalysts. The catalytic performances of the supported Ni catalysts on different oxides including SiO2, TiO2, ZrO2, γ-Al2O3, and MgO as well as several com. hydrogenation catalysts were investigated. The Ni/ZrO2 catalyst presented the highest 5-AP yield. The characterization results of the oxide-supported Ni catalysts showed that the Ni/ZrO2 catalyst possessed high reducibility and a high surface acid d., which lead to the enhanced activity and selectivity of the catalyst. The effect of reaction parameters on the catalytic performance of the Ni/ZrO2 catalyst was studied, and a high 5-AP yield of 90.8% was achieved in the reductive amination of 2-HTHP aqueous solution under mild conditions of 80°C and 2 MPa H2. The stability of the Ni/ZrO2 catalyst was studied using a continuous flow reactor, and only a slight decrease in the 5-AP yield was observed after a 90-h time-onstream. Addnl., the reaction pathways for the reductive amination of 2-HTHP to synthesize 5-AP were proposed. The experimental process involved the reaction of Pentane-1,5-diol(cas: 111-29-5).Computed Properties of 111-29-5
