In this paper, standard molar energies of combustion of 2-oxazolidinone and 3-acetyl-2-oxazolidinone are reported. The experimental values, obtained from static-bomb combustion calorimetry, are ?(1465.42 ± 0.52) kJ·mol?1 and ?(2350.86 ± 0.84) kJ·mol?1, respectively. Using these combustion energy values, the standard molar enthalpies of formation, in crystalline phase, for the aforesaid compounds were calculated. These values were also determined, and the corresponding values are ?(430.30 ± 0.96) kJ·mol?1 and ?(617.72 ± 1.58) kJ·mol?1, respectively. The standard molar enthalpies of sublimation at T = 298.15 K were experimentally obtained by using the well-known Knudsen effusion method. The obtained values are (84.20 ± 3.22) kJ·mol?1 and (82.36 ± 1.84) kJ·mol?1, respectively. From the above experimental results, the standard molar enthalpies of formation in gas-phase of the compounds were derived. The values are: ?(346.10 ± 3.36) kJ·mol?1 and ?(535.36 ± 2.43) kJ·mol?1, respectively. To support the consistency of the experimental results presented here, enthalpies of formation in gas-phase, using the G4 composite method, were carried out as well. Experimental results suggest that the formation of intermolecular hydrogen bonds between the nitrogen (at ring’s position 3, see Fig. 1) with the oxygen (at ring’s position 2, see Fig. 1) contributes to the values of temperature and enthalpy of fusion, enthalpy of sublimation, and enthalpy of formation in solid phase.

The reaction of alkynyl carboxylic acids, glyoxylic acid derivatives, and amines in the presence of a copper catalyst afforded the corresponding propargyl amines in good yields. The alkynyl carboxylic acid of this coupling reaction shows similar reactivity to that of a terminal alkyne, and the reactivity of the glyoxylic acid is almost identical to that of an aldehyde. When 2-aminopyridine was employed as the amine source, imidazopyridine derivatives were formed in good yields.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.Related Products of 497-25-6, you can also check out more blogs about497-25-6

A facile approach to (E)-alpha-haloenamide moieties from ynamides using bromo- or iodotrimethylsilane is described. The simple protocol enables a regio- and stereospecific hydrohalogenation of the triple bond in gram-scale and provides a general entry for synthesis of novel enamide analogues.

The catalyzed pathway has a lower Ea, but the net change in energy that results from the reaction is not affected by the presence of a catalyst. In my other articles, you can also check out more blogs about 497-25-6 Related Products of 497-25-6

New antibiotics are desperately needed to combat the increasing number of antibiotic resistant strains of pathogenic microorganisms. Natural products remain the most propitious source of novel antibiotics. It is widely accepted that actinobacteria are prolific producers of natural bioactive compounds. We argue that the likelihood of discovering a new compound having a novel chemical structure can be increased with intensive efforts in isolating and screening rare genera of microorganisms. Screening rare actinomycetes and their previously underrepresented genera from unexplored environments in natural product screening collections is one way of achieving this. Rare actinomycetes are usually regarded as the actinomycete strains whose isolation frequency is much lower than that of the streptomycete strains isolated by conventional methods. The relevance of the rare actinomycetes in this regard can also be demonstrated by the fact that many of the successful antimicrobial agents currently available in the market are produced by them. This chapter focuses on the bioactive secondary metabolites from rare actinomycetes with emphasis on their structures, relevant biological activities, source organisms, covering over 150 structures of different bioactive compounds produced by them with 84 citations. Its aim is to give the reader a brief view of the bioactive compounds from the rare actinomycetes and we wish to update our understanding of the potential of the rare actinomycetes by focusing on their biodiscovery potential. The emphasis is placed on new compounds discovered from these microorganims with bioactive potential. Copyright

Catalysts are substances that increase the reaction rate of a chemical reaction without being consumed in the process. A catalyst does not appear in the overall stoichiometry of the reaction it catalyzes. You can also check out more blogs about 497-25-6Reference of 497-25-6

Application of 497-25-6, The reaction rate of a catalyzed reaction is faster than the reaction rate of the uncatalyzed reaction at the same temperature.497-25-6, Name is Oxazolidin-2-one, molecular formula is C3H5NO2. In a Conference Paper，once mentioned of 497-25-6

Thermal degradation of monethanolamine (MEA) is quantified as a function of initial amine concentration, CO2 loading, and temperature over a range of expected stripper conditions in an amine absorber/stripper unit. The sum of the degradation products N,N’-di(2-hydroxyethyl)urea, 1-(2-hydroxyethyl)-2-imidazolidone, and N-(2-hydroxyethyl)ethylenediamine make up the majority of total MEA loss. The temperature dependent rate constant has an activation energy similar to diethanolamine (DEA) of 29 kcal/mole which corresponds to a quadrupling of the degradation rate when the stripper temperature is increased 17 {ring operator}C. At 135 {ring operator}C the degradation rate varies from 2.5 to 6% per week. Using speciation data from an Aspen model of a stripper unit, losses in the packing are significant, but the majority of MEA loss occurs in the reboiler and reboiler sump. Thermal degradation is minor when the reboiler temperature is held below 110 {ring operator}C.

The result showed that such a combination of chemo- and biocatalysis improved the catalytic yield more than two times compared with that of sole metal catalysis.I hope my blog about 497-25-6 is helpful to your research. Application of 497-25-6
