The chemical properties of alicyclic heterocycles are similar to those of the corresponding chain compounds. Compound: 4-(Hydroxymethyl)-1,3-dioxolan-2-one, is researched, Molecular C4H6O4, CAS is 931-40-8, about Kinetics modeling of glycerol carbonate synthesis from glycerol and urea over amberlyst-15 catalyst, the main research direction is glycerol carbonate urea amberlyst catalyst kinetic modeling.SDS of cas: 931-40-8.

Synthesize of glycerol carbonate from glycerol and urea is an attractive path as glycerol carbonate has a large potential as a green solvent. The aim of the present study was to develop a kinetic model of glycerol carbonate synthesis with amberlyst-15 resins as a catalyst. The investigation was carried out at various temperatures from 353 to 383 K and catalyst loading from 0.25 to 1 weight% of glycerol. The exptl. results indicated that both temperature and catalyst loading have an important effect on the glycerol conversion. According to the exptl. result, the highest glycerol conversion was found 36.90% which was obtained using a molar ratio of urea to glycerol 1:3, catalyst loading of 1 weight%, stirrer speed of 700 rpm, the temperature of 383 K and reaction time of 5 h. A kinetic model was developed based on elementary steps that take place over the catalyst. The model estimated that the pre-exponential factor was 2.89.104 mol.g-1.min-1 and the activation energy was 50.5 kJ.mol-1. By comparing the simulation and exptl. data, it could be inferred that the model could predict the trend of exptl. data well over the range of temperature and catalyst loading investigated in the present study.

From this literature《Kinetics modeling of glycerol carbonate synthesis from glycerol and urea over amberlyst-15 catalyst》,we know some information about this compound(931-40-8)SDS of cas: 931-40-8, but this is not all information, there are many literatures related to this compound(931-40-8).

Petryaev, E. P.; Vasil’ev, G. N.; Maslovskaya, L. A.; Shadyro, O. I. published an article about the compound: 2-Chloroethyl acetate( cas:542-58-5,SMILESS:CC(OCCCl)=O ).Formula: C4H7ClO2. Aromatic heterocyclic compounds can be classified according to the number of heteroatoms or the size of the ring. The authors also want to convey more information about this compound (cas:542-58-5) through the article.

γ-Radiolysis of I (R = R1 = H) gave MeCHO, HCO2Et, C2H4, and CO2, whereas radiolysis of I (R = R1 = Me) gave only MeCHO and Me2CO. The 1st reaction proceeded via dioxolan-2-yl and -4-yl radicals; the 2nd proceeded only via the latter radical. Radiolysis of I (R = Me, R1 = H) and AcOCH2CH2Cl suggested that dioxolanyl radicals can fragment simultaneously at 2 bonds.

From this literature《Ways of fragmenting radicals of 1,3-dioxolanes》,we know some information about this compound(542-58-5)Formula: C4H7ClO2, but this is not all information, there are many literatures related to this compound(542-58-5).
