2,6-lutidine is formed from acetone, methanol and ammonia over ZSM-5 type zeolitic catalysts. Selectivity to 2,6-lutidine is found to be highest at relatively high Si/Al ratios. At higher Si/Al ratios a lower steady state adsorption of lutidine (0.6 lutidine/Al) is observed under reaction conditions. Possible mechanisms are discussed in the light of an experiment with 13C-labelled methanol.

A new aerobic copper-catalyzed three-component synthesis of azaaryl-substituted quinazolines has been developed, which featured inexpensive methylazaarenes as C1 sources, easily available copper salts as the catalysts and O2 as a sole oxidant. The transformation had very good substrate applicability towards methylazaarenes, and various azaaryl-substituted quinazolines were obtained in moderate to good yields.

A gas chromatograph or a direct-insertion probe interfaced to a medium-resolution mass spectrometer set at about 3000 resolution is used in the multiple ion detection (MID) mode to monitor the intensity of the CH2N+ ion at m/q 28.This configuration converts the system into a nitrogen compound specific detector.Practicability of this system in terms of levels of detection, quantitation, etc., is demonstrated by use of authentic nitrogen compound mixtures, gasolines, and coals.The sinificance of CO+ and C2H4+ ion monitoring, also found at m/q 28, is discussed.

The catalyzed pathway has a lower Ea, but the net change in energy that results from the reaction is not affected by the presence of a catalyst.

The extraction residue from Shengli lignite was sequentially dissolved with cyclohexane, benzene, methanol, ethanol, and isopropanol in an autoclave at 320 C to afford soluble portions (SPs) 1?5 (SP1-SP5) and the final residue (FR). The total yield of SP1-SP5 is ca. 55.1%. FR was subjected to ruthenium ion-catalyzed oxidation and the resulting products were isolated from the reaction mixture and esterified. Both the esterified products and SP1-SP5 were analyzed with a gas chromatograph/mass spectrometer. In total, 342 compounds were identified in SP1-SP5. They can be classified into normal alkanes, branched alkanes, alkenes, alkanedienes, arenes, alkanols, methylcycloalkanes, alkenols, alkylbenzenemethanols, arenols, anisol and substituted anisols, polymethyldihydrobenzofurans, arenofurans, dibenzofurans, ethoxymethylbenzenes, aldehydes, ketones, esters, nitrogen-containing organic compounds, sulfur-containing organic compounds, and other compounds. Among the compounds, arenols are predominant in SP1 and SP2 and the main compounds in SP3, while the main compounds in SP4 and SP5 are esters and arenes, respectively. According to the esterified products identified, the products from FR oxidation can be grouped into non-benzene ring carboxylic acids (NBCAs) and benzenepolycarboxylic acids (BPCAs). The total yield of BPCAs is much higher than that of NBCAs, suggesting that FR is rich in condensed aromatic moieties.

Chemical standards are used to calibrate ion mobility spectrometers (IMS) for accurate and precise identification of target compounds. Research over the past 30 years has identified several positive and negative mode compounds that have been used as IMS standards. However, the IMS research community has not come to a consensus on any chemical compound(s) for use as a reference standard. Also, the reported K0 values for the same compound analyzed on several IMS systems can be inconsistent. In many cases, mobility has not been correlated with a mass identification of an ion. The primary goal of this work was to provide mass-identified mobility (K0) values for standards. The results of this work were mass-identified K0 values for positive and negative mode IMS chemical standards. The negative mode results of this study showed that TNT is a viable negative mode reference standard. New temperature-dependent K0 values were found by characterizing drift gas temperature and water content; several examples were found of temperature-dependent changes for the ion species of several standards. The overall recommendation of this study is that proposed IMS standards should have temperature-dependent K0 values quoted in the literature instead of using a single K0 value for a compound.

Changes in the absorbance of nickel chelate of resacetophenone oxime are observed, on the addition of heterocyclic N-bases to a solution of the nickel chelate in cyclohexanone.This behaviour is attributed to the adduct formation of nickel chelate with pyridine or substituted pyridines.All the N-bases form monoadducts with the nickel chelate, except 1,10-phenanthroline which forms a diadduct.The stabilities of the nickel adduct increase in the following order of the bases: 3,5-lutidine < 2,4,6-collidine < 3-picoline < 4-picoline < pyridine < 2,2'-bipyridyl < 2,9-neocuproin < 1,10-phenanthroline. Because a catalyst decreases the height of the energy barrier, its presence increases the reaction rates of both the forward and the reverse reactions by the same amountFormula: C7H9N, you can also check out more blogs about108-47-4
