Gas-phase dissociative electron attachment (DEA) measurements to N-methylformamide (NMF, HC(O)NHCH3), a simple molecule containing the peptide linkage, were performed. The anion yields as a function of electron energy below 15 eV were obtained using a crossed molecular beam/Quadrupole Mass Spect...
This paper reports the thermodynamic properties of CsF in (Urea + H2O) or (N-methylformamide + H2O) mixed solvents by potentiometric method at 298.2 K. The experimental data are fitted using the Pitzer, modified Pitzer and extended Debye-Hückel equation. The mean activity coefficients, osmotic ...
In this work transport properties of ammonium nitrate in N-methylformamide (NMF) and N,N-dimethylformamide (DMF) were investigated in order to explain the nature of solute–solvent interactions in diluted and concentrated ammonium nitrate solutions. The electrical conductivity was measured in th...
Density, viscosity and speed of sound of three binary liquid systems: N-methylformamide (N-MFA) with carboxylic acids (ethanoic acid, propanoic acid and butanoic acid) have been determined at T = (303.15–318.15) K over the entire composition range. These experimental data have been used to calc...
Classical molecular dynamics simulations have been carried out to investigate dynamical properties of cis-trans mixture of liquid N-methylformamide at eight different temperatures (278–423 K) and four pressures ranging from 0.1 MPa to 300 MPa. At 298 K and 0.1 MPa, it is observed that cis-NMF i...
In this work two new perchlorate based inorganic salts with N-methylformamide (NMF) as a crystal solvate, Cu(ClO4)2·4NMF and Ni(ClO4)2·6NMF were synthesized and their structures confirmed by X-ray analysis. The influence of water content on absorption spectra M(ClO4)2·xNMF (where M = Co, Ni o...
The molecular interaction between the polar systems of propan-1-ol and propionaldehyde for various mole fractions at different temperatures were studied by determining the frequency dependent complex dielectric permittivity by using the open-ended coaxial probe technique method in the microwave ...
The equilibrium between propionaldehyde + propane-1,1-diol + 2,4,6-triethyl-1,3,5-trioxane has been characterized, for the first time, in aqueous solution using NMR techniques. The diffusion coefficients and the molar percentages at different temperatures have been also reported.
3-Hydroxypropionic acid (3-HP), an important C3 chemical for a bio-based industry, is natively produced by Lactobacillus reuteri from glycerol. Conversion of glycerol occurs via the intermediate 3-hydroxypropionaldehyde (3-HPA), followed by an ATP-producing pathway initiated by the CoA-acylating...
Oxidation of propanol by chromic acid produces propionaldehyde under kinetic condition [propanol]T ≫ [Cr(VI)]T. This oxidation reaction is performed also in presence of micellar catalysts (anionic, cationic and neutral) and hetero-aromatic nitrogen bases promoters (picolinic acid, 2,2′-bipyridi...
The reactions of Ni+ with propionaldehyde in the gas phase have been systematically investigated using density functional theory at the B3LYP/def2-TZVP level. The decomposition reaction mechanism has been identified. Our calculations indicated that Ni+ can assist decomposition of propionaldehyde...
Dehydration of 1,2-propanediol has been investigated over a range of zeolite catalysts with different pore structures and acidity. The reaction forms part of a two-step process for the conversion of glycerol to propionaldehyde. The effects of reaction temperature, concentration, space velocity, ...
In the USA, oxo chemicals specialist Oxea has begun construction work on a new world-scale propanol plant at its Bay City production site in Texas. Once commissioned, ‘Propanol 2’ will add a capacity of 100 000 tonnes/year of propanol and 40 000 tonnes/year of propionaldehyde, the company says...
The propionaldehyde infrared regional integrated area reported by Köroğlu et al. were re-examined. Even though the spectrum seems to be recorded correctly, the comparison between their values with the data obtained by the integration of the propionaldehyde spectrum available in the PNNL database...
Oxygen-derived free radicals (ROS) have been identified to contribute significantly to ischemia–reperfusion (I/R) injury by initiating chain reactions with polyunsaturated membrane lipids (lipid peroxidation, LPO) resulting in the generation of several aldehydes and ketones. Due to their volati...
The use of oxygenated biofuels reduces the greenhouse gas emissions; however, they also result in increased toxic aldehyde by-products, mainly formaldehyde, acetaldehyde, acrolein, and propionaldehyde. These aldehydes are carcinogenic and/or toxic and therefore it is important to understand thei...
The influence of the carbon support characteristics on Pd loading, dispersion and activity in Pd/C catalysts has been analyzed. Several carbon nanomaterials, including multi-walled CNTs, nitrogen-doped CNTs, sulfur-doped CNTs, large- and small-diameter nanofibers, few-layer graphene, and a fibro...
The aim of this study was to investigate anesthetic efficacy of myrcene and linalool on Cyprinus carpio in comparison with eugenol. The fish were exposed to 150, 200, 400, 600, 800, 1000 and 1200 ppm myrcene, 200, 400, 600, 800, 1000, 1200, 1400 and 1600 ppm linalool, and 25, 35, 50, 75, 100, 15...
This paper examines the use of two different sets of standards, n-alkanes and a more structurally diverse group of cyclic and polycyclic molecules to evaluate the vaporization enthalpies and vapor pressures of (+) longifolene(−)-isolongifolene and β-myrcene using correlation gas chromatography....
β-Myrcene (MYR) is 7-methyl-3-methylene-1,6-octadiene, a chemical compound classified as a monoterpene. It is essential for the manufacture of menthol, such as menthol. MYR is also a fragrance and flavoring agent. In June 2017, the International Agency for Research on Cancer (IARC) assessed thi...
