A library of 52 distyryl and 9 mono-styryl cationic dyes was synthesized and investigated with respect to their optical properties, propensity to aggregation in aqueous medium, and capacity to serve as fluorescence ?light-up? probes for G-quadruplex (G4) DNA and RNA structures. Among the 61 compounds, 57 dyes showed preferential enhancement of fluorescence intensity in the presence of one or another G4-DNA or RNA structure, while no dye displayed preferential response to double-stranded DNA or single-stranded RNA analytes employed at equivalent nucleotide concentration. Thus, preferential fluorimetric response towards G4 structures appears to be a common feature of mono- and distyryl dyes, including long-known mono-styryl dyes used as mitochondrial probes or protein stains. However, the magnitude of the G4-induced ?light-up? effect varies drastically, as a function of both the molecular structure of the dyes and the nature or topology of G4 analytes. Although our results do not allow to formulate comprehensive structure?properties relationships, we identified several structural motifs, such as indole- or pyrrole-substituted distyryl dyes, as well as simple mono-stryryl dyes such as DASPMI [2-(4-(dimethylamino)styryl)-1-methylpyridinium iodide] or its 4-isomer, as optimal fluorescent light-up probes characterized by high fluorimetric response (I/I0 of up to 550-fold), excellent selectivity with respect to double-stranded DNA or single-stranded RNA controls, high quantum yield in the presence of G4 analytes (up to 0.32), large Stokes shift (up to 150 nm) and, in certain cases, structural selectivity with respect to one or another G4 folding topology. These dyes can be considered as promising G4-responsive sensors for in vitro or imaging applications. As a possible application, we implemented a simple two-dye fluorimetric assay allowing rapid topological classification of G4-DNA structures.

A three-step degradation, including sequential ultrasonic extraction (UE), sequential thermal extraction (TE), and ruthenium ion-catalyzed oxidation (RICO), of Xianfeng lignite (XL) was performed to characterize the organonitrogen species (ONSs) in XL. More than 87.3% of organic matter in XL was converted into soluble portions through the degradation. The analysis with X-ray photoelectron spectrometer shows that pyrrolic, amino, and quaternary nitrogen species are the main nitrogen forms both in XL and its residue from UE, while nitroaromatics, chemisorbed N-oxides, and pyrrolic nitrogen are predominant in the residue from TE. A series of ONSs, including pyridines, quinolines, benzo[d]imidazoles, and arylamines, were identified in the extracts from TE of the UE residue according to GC/MS analysis. Among the ONSs, pyridines and quinolines are the most abundant. The ONSs could be released by thermally destroying noncovalent bonds, such as hydrogen bonds and aromatic pi – pi interactions, during TE of the UE residue. Most of ONSs released from RICO of the TE residue could be generated from the degradation of nitrogen-containing macromolecular aromatics in XL matrix (XLM). Nitrobenzenecarboxylic acids are the most abundant ONSs released from RICO of the TE residue and should be released by the degradation of macromolecular nitroaromatics in XLM.

Sewage sludge was pyrolysed in a quartz reactor at 350, 450, 550 and 950 C. The pyrolysis oils from the sewage sludge were characterized in detail by means of gas chromatography-mass spectrometry (GC-MS). Changes in the composition of the oils related to the process conditions were assessed by normalizing the areas of the peaks. It was demonstrated that, as the temperature of pyrolysis increased from 350 to 950 C, the concentration of mono-aromatic hydrocarbons in the oils also increased. Conversely, phenol and its alkyl derivatives showed a strong decrease in their concentration as temperature rose. Polycyclic aromatic hydrocarbons (PAHs) with two to three rings passed through a maximum at a pyrolysis temperature of 450 C. PAHs with 4-5 rings also presented a major increase as temperature increased up to 450 C, the concentration at 950 C being slightly higher than that at 450 C. Quantification of the main compounds showed that sewage sludge pyrolysis oils contain significant quantities of potentially high-value hydrocarbons such as mono-aromatic hydrocarbons and phenolic compounds. The oils also contain substantial concentrations of PAHs, even at the lowest temperature of 350 C. The pathway to PAH formation is believed to be via the Diels-Alder reaction and also via secondary reactions of oxygenated compounds such as phenols.

Catalysts allow a reaction to proceed via a pathway that has a lower activation energy than the uncatalyzed reaction. Product Details of 108-47-4, In heterogeneous catalysis, catalysts provide a surface to which reactants bind in a process of adsorption. 108-47-4, name is 2,4-Dimethylpyridine.

Stability constants and thermodynamic data are reported for coordination of piperidine, pyridine, and substituted pyridines to the cobalt(II) and zinc(II) complexes of octaethylporphyrin (OEP), t-octaethylchlorin (OEC) and the tct-and ttt-isomers of octaethylisobacteriochlorin (OEiBC) in toluene, cyclohexane, and chloroform solution at 25.0 C. Under the conditions of the study, only 1:1 complexes are formed. With the exception of the case of 2-substituted pyridines, the stability constants, log K, correlate roughly with the base strength of the nitrogenous ligand but correlate closely with the log K for coordination of the base to Zn(OEP). A cis-influence of the macrocycle saturation level on the stability constants is observed. Stability constants for coordination of a given ligand to OEiBC complexes are typically 4 times greater than those for coordination to OEP complexes and 1.8 times greater than those for coordination to OEC complexes. The stability constants of both Co- and Zn(OEiBC) complexes were unaffected by the stereochemistry (tct vs ttt) of the ethyl substituents, unlike the case for nickel. DeltaH and DeltaS vary between -8 and -12 kcal/mol and -12 and -24 cal K-1 mol-1, respectively, and correlate linearly with each other. They do not correlate directly with either log K or the saturation level of the macrocycle. For most bases, log K is greater for the zinc complexes than for the cobalt complexes. However, for 3,5-dichloropyridine, log K is greater for the cobalt complexes. The acid dissociation constants for the free-base compounds H2(OEP), H2(OEC), and H2(OEiBC) were measured in THF/n-butanol solution. All three compounds ionize to dianions by simultaneous loss of two protons. OEP and OEiBC have pKa = 15.9. OEC is a weaker acid with pKa = 16.6. The increase in log K with macrocycle saturation level does not correlate with the acidity of the respective free bases, but the latter is not necessarily representative of the sigma-donor strength of the macrocycle dianion. Solvation and pi-effects are not responsible for either the dependence of log K on macrocycle saturation level or the reversal for weak bases of the relative Lewis acid strengths of the cobalt and zinc complexes. The latter is attributed to a relief of strain due to core expansion that occurs upon ligand coordination to cobalt complexes. Cobalt complexes are more sensitive than zinc complexes to steric interactions with the ortho-substituents of a pyridine ligand owing to the much smaller out-of-plane displacement of the cobalt atom compared to the zinc atom in five-coordinate complexes.

The oxidative degradation of aqueous, concentrated 2-amino-2-methyl-1- propanol (AMP)/monoethanolamine (MEA) mixture has been investigated in batch reactors at temperatures in the range of 100-140C, and oxygen pressures in the range of 250-350 kPa. The oxidation pathway of individual AMP was proposed before attempting to investigate the oxidation of AMP/MEA blend. As compared with degradation of single MEA and AMP, no cross product was found in the degraded AMP/MEA blend under the experimental conditions. This result showed that AMP and MEA could be oxidized in parallel in the mixture. Both the overall degradation rates of MEA and AMP increased with raising temperature and oxygen partial pressure. MEA degraded faster than AMP in the blend under all the experimental conditions. The degradation rate of AMP decreased indicating MEA protects AMP from oxidation in the mixture when initial MEA concentration was increased.
