In this work, the weakest thermodynamic conditions for the auto-ignition of mixtures containing nitromethane were experimentally determined by using the rapid compression machine facility. Results show there is a narrow weak ignition region between ignition and non-ignition. The weak ignition re...

Nitromethane anion and nitromethane dimer, trimer, and hydrated cluster anions were studied by photoelectron spectroscopy. Vertical detachment energies, estimated electron affinities, and solvation energies were obtained from the photoelectron spectra. Cluster structures were investigated using ...

The present work reports new experimental data for premixed flames of nitromethane, CH3NO2, at atmospheric pressure, and an evaluation of two contemporary kinetic mechanisms based on these new flame studies as well as previously published experimental data on laminar burning velocity and ignitio...

A new study of the millimeter wave spectrum of nitromethane, CH3NO2, is reported. The new measurements covering the frequency range from 49 GHz to 237 GHz have been carried out using the spectrometer in IRA NASU (Ukraine). Transitions belonging to the |m| ≤ 8 torsional states have been analyzed...

Nitromethane dissolved in carbontetrachloride or cyclohexane as inert solvents, exhibits some of its unique chemical properties in such solutions. Spectroscopic evidence reveals that the molecules are found as discrete entities in the concentration range of about 0.05–0.18 M. Beyond this concen...

An experimental study was conducted on droplet combustion of the monopropellant pure nitromethane (NM) as well as NM blended with methanol. Pure NM droplet combustion was conducted in a quiescent atmosphere of air with the droplets supported at the tip of quartz fibers under normal gravity. Addi...

Two new series of 1,2-benzisothiazol-3(2H)-one-1,1-dioxide derivatives containing either five membered heterocyclic rings or aryl hydrazones were synthesized and evaluated for their in vitro COX-1/COX-2 inhibitory activity. In vivo anti-inflammatory evaluation revealed that benzenesulfonamides b...

The alkylation of the monolithium derivative 5 of 2-(chloromethyl)-3-tosylpropene (1) with bromo- or iodo-methyltrimethylsilane affords the β-silyl sulfone 7, which after nucleophilic substitution of the chlorine atom followed by β-elimination of tosyltrimethylsilane, promoted by tetrabutylamm...

Treatment of 2,3-diiodo-1-(phenylsulfonyl)-1-propene (DIP) with various trimethylsilyl enol ethers in the presence of silver tetrafluoroborate gives alkylation products derived from SN2 displacement of the terminal halide. These compounds readily cyclize with base to produce substituted furans.

The relative rates of acid-catalyzed deoxysilylation of 2-trimethylsilyl-1- hydroxyethane, 4, 1-trimethysilyl-2-hydroxypropane, 5, 1,3-bis(trimethysilyl)- 2-hydroxypropane, 6, and 1-trimethylsilyl-2-methyl-2-hydroxypropane, 7, were found to be 1 : 103.30 : 105.92 : 106.77, respectively, in 9 vol...

The present report describes the preparation and characterization of several N-2-(trimethylsilyl)ethyl-N-nitrosocarbamates, designed as precursors to thermally unstable secondary N-nitrosocarbamate anions via fluoride-assisted cleavage. X-ray structural studies demonstrate that the core N-nitros...

A convenient method for the synthesis of N,N-bis(trimethylsilyl)alkylamines has been reported. N-(Trimethylsilyl)diethylamine incorporated with a stoichiometric amount of methyl iodide was effective to convert primary amines, especially aromatic amines, and their monotrimethylsilyl derivatives i...

Aminofluoroalkylation of various heteroarenes or substituted benzenes with the N-trimethylsilyl hemiaminals, prepared from 1,1,1,3,3,3-hexamethyldisilazane and gaseous trifluoroacetaldehyde, smoothly underwent at room temperature in the presence of a Lewis acid. [(1-Aryl-2,2,2-trifluoro)ethyl]am...

Methoxycarbonylation of a variety of amines into the corresponding methyl carbamates was accomplished by allowing them to react with (trimethylsilyl)diazomethane TMSCHN2 under bubbling of CO2. The reaction was performed at room temperature for a period of ca. 2 h in benzene–MeOH (4/1 v/v), whic...

Bis(trimethylsilyl)ethylamine (BTMSEA) was synthesized and characterized as CVD precursor for silicon carbonitride SiCxNy films synthesis (vapor pressure, thermodynamic modeling).

Capillary zone electrophoresis (CZE) and affinity capillary electrophoresis (ACE) were applied to study the interaction between netropsin and a 14mer double-stranded DNA (dsDNA). The use of a polyacrylamide coated capillary can suppress the electroosmotic flow (EOF) and the adsorption of DNA ont...

Making use of amide activation, a convenient and short path synthesis of optically pure ω-heterocyclic-β-amino acids has been achieved from (1R,3R)- and (1R,3S)-5-oxo-1-(1-phenyl-ethyl)-pyrrolidine-3-carboxylic acid methyl ester. The key step of the synthesis involves a regiospecific ring-chai...

Thermohydrolysis in aqueous acidic (sulfuric or chlorhydric) solutions is one of the main processes to produce titania particles.
