The origin of a common compound about 931-40-8

Different reactions of this compound(4-(Hydroxymethyl)-1,3-dioxolan-2-one)Recommanded Product: 931-40-8 require different conditions, so the reaction conditions are very important.

Epoxy compounds usually have stronger nucleophilic ability, because the alkyl group on the oxygen atom makes the bond angle smaller, which makes the lone pair of electrons react more dissimilarly with the electron-deficient system. Compound: 4-(Hydroxymethyl)-1,3-dioxolan-2-one, is researched, Molecular C4H6O4, CAS is 931-40-8, about A selective synthesis of glycerol carbonate from glycerol and urea over Sn(OH)2: a solid and recyclable in situ generated catalyst.Recommanded Product: 931-40-8.

In this work, we report a selective and straightforward process to synthesize glycerol carbonate from urea and glycerol using a simple but com. unavailable catalyst (Sn(OH)2). This catalyst was generated in situ from the reaction of Sn(II) halides and urea during the glycerol carbonatation process. Effects of main reaction parameters (i.e., temperature, molar ratio of urea to glycerol, catalyst concentration) were investigated. Different tin halides were assessed as catalytic precursors, with SnCl2 being the most efficient. We found that Sn(OH)2-catalyzed glycerol carbonation reactions with urea achieved high conversion and selectivity (ca. 87 and 85%, resp.). The samples of Sn(OH)2 generated in situ or previously synthesized were equally active and selective catalysts toward glycerol carbonate were successfully reutilized without loss activity. This is a very attractive route based on two inexpensive and readily available feedstocks in a chem. cycle that, overall, results in the chem. fixation of carbon dioxide and, concomitantly, adds value to glycerol, a biodiesel byproduct.

We’ll tell you more about this compound (cas:931-40-8).

We have synthesized a set of aromatic mono- and bis(guanidines) which are highly effective binary catalytic systems (guanidine/cocatalyst) for the formation of cyclic carbonates. The presence of multiple N-H bonds causes a modification in the traditional mechanism proposed for the synthesis of cyclic carbonates catalyzed by guanidines through the formation of hydrogen bonds between the oxygen atom of the epoxide and the N-H groups of the guanidines. This change allows a considerable reduction of the reaction temperature and CO2 pressure employed in this process.

Computed Properties of C4H6O4. Aromatic compounds can be divided into two categories: single heterocycles and fused heterocycles. Compound: 4-(Hydroxymethyl)-1,3-dioxolan-2-one, is researched, Molecular C4H6O4, CAS is 931-40-8, about Disordered structure of ZnAl2O4 phase and the formation of a Zn NCO complex in ZnAl mixed oxide catalysts for glycerol carbonylation with urea. Author is Nguyen-Phu, Huy; Shin, Eun Woo.

The effect of a disordered ZnAl2O4 spinel structure on glycerol carbonylation with urea was investigated with pure ZnAl2O4 (c-ZnAl2O4) and ZnAl mixed oxide (c-ZnAlO) prepared by a citrate complex method, and ZnAl phys.-mixed oxide (p-ZnAlO). During catalysts preparation, a disordered bulk ZnAl2O4 phase generated disordered sites on the surface: the Al3+ cations substituting for Zn2+ cations at the tetrahedral sites, and the surface oxygen vacancy corresponding to the Zn2+ cations substituting for Al3+ cations at the octahedral sites. The disordered surface sites increased in order of p-ZnAlO < c-ZnAlO < c-ZnAl2O4, which was proportional to the surface acidity. c-ZnAlO exhibited the best reaction performance due to the existence of a solid zinc isocyanate (Zn NCO) complex on the disordered sites. Here, we proposed that the solid Zn NCO complex preferentially generated glycerol carbonate (GC), while the liquid Zn NCO complex produced both GC and zinc glycerolate.

Most of the compounds have physiologically active properties, and their biological properties are often attributed to the heteroatoms contained in their molecules, and most of these heteroatoms also appear in cyclic structures. A Journal, Journal of the Serbian Chemical Society called Water glass derived catalyst for the synthesis of glycerol carbonate via the transesterification reaction between glycerol and dimethyl carbonate, Author is Xu, Lanlan; Wang, Song; Okoye, Patrick U.; Wang, Jianye; Li, Sanxi; Zhang, Linnan; Zhang, Ailing; Tang, Tao, which mentions a compound: 931-40-8, SMILESS is O=C1OCC(CO)O1, Molecular C4H6O4, Reference of 4-(Hydroxymethyl)-1,3-dioxolan-2-one.

Water glasses with different modulus (mole ratio of SiO2 to Na2O) were applied as a raw material to prepare five solid base catalysts for the synthesis of glycerol carbonate (GC) by the transesterification reaction between glycerol and di-Me carbonate (DMC). The structure and properties of the five water glass-derived catalysts were investigated by XRD, FT-IR, FESEM, BET and acid-base titration methods. The catalysts with relatively low modulus, including 1.0, 1.5 and 2.0, presented good catalytic abilities, among which the catalyst derived from water glass with 2.0 modulus (WG-2.0) was chosen as the optimal catalyst in the synthesis of GC. This was because WG-2.0 showed the highest BET surface area, relatively high total basicity, and needed a less amount of NaOH during the preparation process. In the optimization experiments, this catalyst exhibited good catalytic ability with the glycerol conversion of 96.3% and GC yield of 94.1% under the condition of glycerol to DMC mole ratio of 1:4, WG-2.0 amount of 4 weight %, reaction temperature of 348 K and reaction time of 90 min. Furthermore, the reusability experiment of WG-2.0 was also conducted and the results indicated that WG-2.0 could be reused five times without significant reduction in its catalytic ability.

Most of the natural products isolated at present are heterocyclic compounds, so heterocyclic compounds occupy an important position in the research of organic chemistry. A compound: 931-40-8, is researched, SMILESS is O=C1OCC(CO)O1, Molecular C4H6O4Journal, Journal of Environmental Chemical Engineering called A green and facile production of catalysts from waste red mud for the one-pot synthesis of glycerol carbonate from glycerol, Author is Das, Bikashbindu; Mohanty, Kaustubha, the main research direction is waste red mud green catalyst glycerol transesterification; one pot synthesis.Recommanded Product: 4-(Hydroxymethyl)-1,3-dioxolan-2-one.

In this study, waste red mud (RM) from aluminum industry was calcined at different temperatures between 400 °C-800 °C and was applied as catalysts for the efficient production of glycerol carbonate (GC) through transesterification of glycerol (GL) with di-Me carbonate (DMC). No chem. pretreatments or incorporation of any other foreign active components into the surface of RM was performed before its application as a catalyst. XRD and FTIR anal. revealed that RM calcined at 500 °C (RM-500) possessed the maximum concentration of active NaAlO2 and Ca2SiO4 sites, thus produced the highest catalytic activity (92.02% GC yield). At calcination temperature above 500 °C, hematite became the dominant phase and the concentration of NaAlO2 and Ca2SiO4 decreased, which also decreased the catalytic activity. The RM-500 catalyst showed excellent resistant for the transesterification of GL in the presence of initial impurities like water and methanol. Based on the results of different characterization techniques, a plausible reaction mechanism and the deactivation mechanism was proposed. Further, the kinetic anal. and reusability study was also studied in details.

Computed Properties of C4H6O4. The reaction of aromatic heterocyclic molecules with protons is called protonation. Aromatic heterocycles are more basic than benzene due to the participation of heteroatoms. Compound: 4-(Hydroxymethyl)-1,3-dioxolan-2-one, is researched, Molecular C4H6O4, CAS is 931-40-8, about Recent progress in synthesis of glycerol carbonate and evaluation of its plasticizing properties. Author is de Caro, Pascale; Bandres, Matthieu; Urrutigoity, Martine; Cecutti, Christine; Thiebaud-Roux, Sophie.

The state of the art on the glycerol carbonate (GC) synthesis has been updated since the last published reviews in 2012, 2013, and 2016. Three types of reactions continue to be studied: glycerolysis of urea, transcarbonation of DMC, DEC, or cyclic carbonates with glycerol and reaction using CO2. Among these different routes, DMC and glycerol were selected as the rawmaterials for the GC synthesis in this work since the transcarbonation from these green reagents leads to high yields and selectivities, using mild conditions including a less energy consuming GC separation process. Catalytic conditions using Na2CO3 seem to be a good compromise to achieve a high yield of GC, leading to an easier purification step without GC distillation Mild temperatures for the reaction (73-78°C) as well as a low waste amount confirmed by the E-factor calculation, are in favor of controlled costs. Plasticizing properties of synthesized GC were compared to the behaviors of a com. plasticizer and natural dialkyl carbonates, for a colorless nail polish formulation. The resulting films subjected to mech. and thermal stresses (DMA and Persoz pendulum) showed the high plasticizing effect of GC toward nitrocellulose based films, probably due to hydrogen bond interactions between GC and nitrocellulose. The GC efficiency gives the possibility to decrease the content of the plasticizer in the formulation. Glycerol carbonate can be thus considered as a biobased ingredient abiding by the green chem. concepts, and safe enough to be used in an ecodesigned nail polish formulation.

Recommanded Product: 931-40-8. The protonation of heteroatoms in aromatic heterocycles can be divided into two categories: lone pairs of electrons are in the aromatic ring conjugated system; and lone pairs of electrons do not participate. Compound: 4-(Hydroxymethyl)-1,3-dioxolan-2-one, is researched, Molecular C4H6O4, CAS is 931-40-8, about Lanthanum nanocluster/ZIF-8 for boosting catalytic CO2/glycerol conversion using MgCO3 as a dehydrating agent. Author is Hu, Chechia; Chang, Chien-Wei; Yoshida, Masaaki; Wang, Ke-Hsuan.

A lanthanum-modified zeolitic imidazolate framework (La/ZIF-8) was developed to produce glycerol carbonate using CO2 and glycerol as raw materials. La/ZIF-8 provides a high catalytic glycerol conversion efficiency owing to its surface-attached nanoclusters of La2O3, which can be viewed as La3+-O2- pairs that strengthen the Lewis basicity and acidity, and the large sp. surface area of ZIF-8. The catalytic glycerol conversion and the yield of glycerol carbonate were 46.5% and 35.3%, resp., using CH3CN as a dehydrating agent. With increase in the amount of CH3CN, the water mols. could react with CH3CN to reduce the selectivity. When an inorganic dehydrating agent, MgCO3, was used to phys. adsorb and remove water mols. in the reaction, the selectivity of the reaction could be increased to over 95%, which is the highest ever reported. Reaction kinetics anal. also revealed that the activation energy of using MgCO3 (5.4 kJ mol-1) as a dehydrating agent is lower than that using CH3CN (7.8 kJ mol-1). Moreover, the La/ZIF-8 could be recycled and reused at least three times with high catalytic performance. This study provides an effective material with dual Lewis basicity and acidity for CO2/glycerol conversion and significantly improves the catalytic performance using an inorganic dehydrating agent.
