Application of 4265-25-2, The reaction rate of a catalyzed reaction is faster than the reaction rate of the uncatalyzed reaction at the same temperature.4265-25-2, Name is 2-Methylbenzofuran, molecular formula is C9H8O. In a Article，once mentioned of 4265-25-2

A dual-zone, continuous feed tubular reactor is developed to assess the potential for formation of products from incomplete combustion in thermal oxidation of common polymers. Solid polymer (cellulose or polystyrene) is fed continuously into a volatilization oven where it fragments and vaporizes. The gas-phase polymer fragments flow directly into a second, main flow reactor to undergo further reaction. Temperatures in the main flow reactor are varied independently to observe conditions needed to convert the initial polymer fragments to CO2 and H2O. Combustion products are monitored at main reactor temperatures from 400 to 850 C and at 2.0-s total residence time with four on-line GC/FIDs; polymer reaction products and intermediates are further identified by GC/MS analysis. Analysis of polymer decomposition fragments at 400 C encompasses complex oxygenated and aromatic hydrocarbon species, which range from high-molecular-weight intermediates of ca. 300 amu, through intermediate mass ranges down to C1 and C2 hydrocarbons, CO, and CO2. Approximately 41 of these species are positively identified for cellulose and 52 for polystyrene. Products from thermal oxidation of cellulose and polystyrene are shown to achieve complete combustion to CO2 and H2O at a main reactor temperature of 850 C under fuel-lean equivalence ratio and 2.0-s reaction time.

The study of the specific reactivity of the ion pairs of alkaline enolates of beta-dicarbonyl compounds shows that the lithium enolates, in spite of their characteristically strong enolate-cation interactions display, especially when compared to sodium enolates, a marked tendency towards O-alkylation.This strong O-/C-nucleophilicity of the lithium ion pairs is not very sensitive to changes in medium polarity (from THF or DME to DMF) but depends on the nature of the alkylating agent, being enhanced with moderately electrophilic alkyl sulfonates or sulfate but lessened with alkyl halides or with very electrophilic sulfonates (triflate).It is suggested that the litium enolate tendency towards O-alkylation is partly the result of a Li(+) – leaving group interaction (especially in the case of the sulfonates) and partly an intrinsic property of the enolate-lithium ion pair; this latter property is discussed in terms of the respective solvation abilities towards cations of the C- and O-alkylation transition states.Some of our results about the nucleophilic reactivity of ion pairs in DMF are at variance with previous reports in the literature.The origin of the discrepancy is discussed.

A fast method utilizing in situ generated CO for the synthesis of phthalides has been developed. DMF and Mo(CO)6 were applied as two alternative CO-sources in these microwave promoted carbonylation-lactone formation reactions. Mo(CO)6 was found to be the more generally applicable CO-source and provided phthalides as well as dihydroisocoumarin, dihydroisoindone, and phthalimide from the corresponding aryl bromide via an efficient CO insertion within a 1h reaction time.

Practical yields of biogas from the anaerobic digestion of macroalgae and, Sargassum muticum in particular, are substantially below the theoretical maximum. There is considerable conjecture about the reasons for the relatively low practical methane yields from seaweed, and polyphenols are suggested as one of the elements in the low yield of methane from brown seaweeds. However, there appears to be little information on the effect of specific phenolics on defined substrates. This paper examines the effect of some simple phenolic compounds, representative of those reported in S. muticum on methane production from a range of model substrates. Three simple phenolics were selected, gallic acid, epicatechin and phloroglucinol; at four addition levels, 0, 0.5, 3.5 and 7.5% w/w of substrate; for four substrates, a readily digested simple organic substance, glycerol, and three polymers found in seaweed, cellulose, alginic acid and the sodium salt of alginic acid. Alginic acid and its sodium salt were found to be recalcitrant with average methane yields of equivalent to only 23?28% of their theoretical methane potential. Methane yield was further reduced by the presence of high concentrations (7% of substrate equivalent to 17.5 mg L?1) of phloroglucinol and epicatechin. None of the phenolic compounds studied appeared to inhibit the breakdown of the simple and readily digested compound, glycerol. Low methane yield in seaweed may be due to the recalcitrance of complex hydrocolloids and phenolic inhibition of the breakdown of more complex molecules in the initial hydrolysis stage of anaerobic digestion, but further research is required.

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.COA of Formula: C28H30O4, you can also check out more blogs about125-20-2

A convergent total synthesis of 13-hydroxyisocyclocelabenzine was developed. (3S)-Methyl 3-amino-3-phenylpropanoate (4) was used as the chiral building block. The 3,4-dihydro-4-hydroxyisoquinolin-1(2H)-one derivative (5), the key fragment for the total synthesis, was prepared by a novel base-catalyzed lactone-lactam ring enlargement (Scheme 3). The resulting target C(13) epimers 3a/3b from macrocyclization (Scheme 4) were separated by repeated flash chromatography. The absolute configuration of the synthetic alkaloid was determined by an X-ray crystal-structure analysis, which enabled us to determine the absolute configuration (9S,13R) for natural 3a with positive [alpha]D.
