"Limiting quantum yield measurements for the disappearance of 1-propanol and propanal: an oxidative reaction study employing a TiO2 based photoreactor."

Abstract:

Relative initial quantum yields [Formula: see text] for the disappearance of 1-propanol and propanal were estimated based on total light intensity entering the reaction vessels. Two types of photocatalytic reactor geometries were compared, a commercial prototype flow reactor with immobilized TiO2 and a conventional reactor with TiO2 dispersion. A maximum relative quantum yield, [Formula: see text], was extrapolated for pure propanol and propanal in both geometries. The high quantum yields were attributed to efficient competition of substrate oxidation with electron–hole recombination, at high

Abstract:

AbstractComplex organic molecules (COMs) have been detected in the gas-phase in cold and lightless molecular cores. Recent solid-state laboratory experiments have provided strong evidence that COMs can be formed on icy grains through ‘non-energetic’ processes. In this contribution, we show that propanal and 1-propanol can be formed in this way at the low temperature of 10 K. Propanal has already been detected in space. 1-propanol is an astrobiologically relevant molecule, as it is a primary alcohol, and has not been astronomically detected. Propanal is the major product formed in the C2H2 + CO

Abstract:

Directly conversion of CO2 to propanol using C2H4 and H2 had succeeded over Au/SiO2 catalyst in one reactor mode. However, application of new dual-reactor concept enhaned the catalytic activity strongly by using two saparated reactors. To this details, a first reactor is used to convert CO2 to CO through the reverse water gas shift (RWGS) reaction, consecutive hydroformylation of C2H4 with resulting CO and H2 to propanal and finally the hydrogenation of propanal to propanol takes place in a second reactor at a different temperature. The selectivity to oxo products (propanol and propanal) incre

Abstract:

Context. 1-propanol (CH3CH2CH2OH) is a three carbon-bearing representative of the primary linear alcohols that may have its origin in the cold dark cores in interstellar space. To test this, we investigated in the laboratory whether 1-propanol ice can be formed along pathways possibly relevant to the prestellar core phase. Aims. We aim to show in a two-step approach that 1-propanol can be formed through reaction steps that are expected to take place during the heavy CO freeze-out stage by adding C2H2 into the CO + H hydrogenation network via the formation of propanal (CH3CH2CHO) as an intermed

Condensation and esterification are important catalytic routes in the conversion of polyols and oxygenates derived from biomass to fuels and chemical intermediates. Previous experimental studies show that alkanal, alkanol and hydrogen mixtures equilibrate over Cu/SiO<sub>2</sub> and form surface alkoxides and alkanals that subsequently promote condensation and esterification reactions.

Carnosine is a naturally occurring dipeptide (β-alanine-L-histidine) which supports physiological homeostasis by buffering intracellular pH, chelating metals, and conjugating with and neutralizing toxic aldehydes such as acrolein.

To examine this, we measured urinary levels of nonconjugated carnosine and its acrolein conjugates (carnosine-propanal and carnosine-propanol) in participants of the Louisville Healthy Heart Study and examined associations with indices of CVD risk.

Abstract:

The continuous-wave (cw) CO2 laser induced decomposition of propylene oxide yields propanal, propanone and methyl vinyl ether as primary isomerization products. The absence of allylol and great amounts of ethene among products of ensuing fragmentation of primary products make the reaction different from conventional thermal decomposition of propylene oxide. CW CO2 laser induced decomposition of methyl vinyl ether affords propanal as isomerization product and shows thermal interconvertibility of propylene oxide and methyl vinyl ether.

Abstract:

Abstract. Volatile organic compound concentration ratios can be used as indicators of halogen chemistry that occurs during ozone depletion events in the Arctic during spring. Here we use a combination of modeling and measurements of [acetone]/[propanal] as an indicator of bromine chemistry, and [isobutane]/[n-butane] and [methyl ethyl ketone]/[n-butane] are used to study the extent of chlorine chemistry during four ozone depletion events during the Polar Sunrise Experiment of 1995. Using a 0-D photochemistry model in which the input of halogen atoms is controlled and varied, the approximate ra

Abstract:

ABSTRACT Chemical evolution in molecular clouds in the interstellar medium is well established, with the identification of over 200 molecules and molecular ions. Among the classes of interstellar organic compounds found are the aldehydes. However, laboratory work on the aldehydes has scarcely kept pace with astronomical discoveries as little quantitative solid-phase infrared (IR) data have been published on any of the aldehydes, and the same is true for important properties such as density, refractive indices, and vapour pressures. In this paper, we examine the IR spectra of solid propanal (HC

Abstract:

Why is LDA such a good base while MeLi is mainly a nucleophile? This communication presents a DFT theoretical study comparing side by side the mechanistic pathways followed during the deprotonation and nucleophilic addition of these two reagents, solvated by THF, onto propanal.

Abstract:

It has been found by gas chromatography that the equilibrium adsorption of propanal, propionic and acetic acids on molybdenum-vanadium oxide catalyst can be described by the Langmuir adsorption isotherm. The existence of carboxylates on the catalyst surface has been proved by IR spectroscopy.

Metakrolinin metakril turşusuna selektiv oksidləşməsini kataliz etmək üçün müxtəlif x qiymətləri olan bir sıra KxH1.1-xCu0.2Cs1(NH4)1.5PVMo11O40 (KxCuCsNH4PVA) katalizatorları sintez edilmişdir. Kalium (K) ionlarının həm struktura, həm də katalitik aktivliyə təsiri ətraflı öyrənilmişdir. Optimal K0.6CuCsNH4PVA Keggin strukturunun ikincil strukturunda geniş səth sahəsi, daha çox turşu sahələri və bol aktiv növlər (V4+/VO2+) nümayiş etdirdi və nəticədə yaxşı katalitik performans təklif etdi. Bundan əlavə, K ionları karbon monoksit və karbon dioksid (birlikdə COX kimi müəyyən edilir) hesabına MAA
