Silica-supported tantalum clusters (on average, approximately tritantalum) were formed by the treatment, in either H(2) or ethane, of adsorbed Ta(CH(2)Ph)(5); the supported catalyst is active for ethane conversion to methane and propane at 523 K, with the used catalyst containing clusters of the same average nuclearity as the precursor.

The production of chemical energy carriers utilizing electrical from renewable sources is essential for the future system. A motored piston engine may be used as a reactor to convert mechanical by pyrolysis methane and ethane; this analyzed here. modeled compression–expansion cycle with detailed kinetics. main products are hydrogen high-energy hydrocarbons such acetylene, ethylene, benzene. To ...

In the title compound, {[Ag(C(30)H(20)N(6))][SbF(6)]}(n), the Ag(+) cation has a three-coordinate environment completed by three N atoms of the 1,2-bis-[(3-cyano-benzyl-idene)hydrazono]-1,2-diphenyl-ethane ligand. The Ag(+) cation coordination geometry is best described as distorted T-shaped. The crystal structure forms a three-dimensional structural polymer.

The understanding of the ethane rotation barrier is fundamental for structural theory and the conformational analysis of organic molecules and requires a consistent theoretical model to differentiate the steric and hyperconjugation effects. Due to recently renewed controversies over the barrier's origin, we developed a computational approach to probe the rotation barriers of ethane and its cong...

In the crystal structure of the title compound, (C(14)H(18)N(6)O(2))·[PtCl(4)], the cation and square-planar anion are located on special positions (on a twofold axis and an inversion centre, respectively). In the crystal structure, N-H⋯Cl hydrogen bonds lead to a staircase-like motif. The central ethane backbone of the cation is disordered over two positions of equal occupancy.

Abstract. We present a method for estimating fossil fuel methane emissions using observations of and ethane, accounting uncertainty in their emission ratio. The ethane:methane ratio is incorporated as spatially temporally variable parameter Bayesian model, with its own prior distribution uncertainty. find that an mitigates bias from fixed, potentially incorrect this propagated into posterior es...

Red pine (Pinus resinosa Ait.) and paper birch (Betulapapyrafera Marsh.) seedlings exposed to sulfur dioxide produced acetaldehyde and ethanol, and exhibited increased production of ethylene and ethane. Gas chromatographic measurement of head space gas from incubation tubes containing leaves or seedlings was a simple method of simultaneously measuring all four compounds. Increased ethylene prod...

Using three different approaches, racemic 1-(perfluoroalkyl)ethylamines were synthesized from perfluoroalkyl iodides or perfluoroalkanoic acids, and further transformed to the corresponding N,N'-disubstituted ethane-1,2-diimines and ethane-1,2-diamines as mixtures of diastereoisomers. Their cyclization afforded imidazolium or dihydroimidazolium salts, which led to silver or palladium complexes ...
